Group of players of Hangzhou Public Security Bureau directly under the Prevention and Control Mobile Brigade squadron Caihe Tangguang Ren, Huang Chun, Chen Liang trio, as usual, driving a car to patrol the area.
Suddenly, Tang Guangren shoulder walkie-talkie came the sound of rapid instruction: “directly under the Prevention and Control Mobile Brigade squadron Caihe group Please note: a license for the knife-wielding masked robbery in Jinhua, Zhejiang G. 3L966 black Mazda traveling in the Hangzhou-Jinhua-Quzhou to elapsed Puyan toll, go to the airport high-speed dial set up the card. ”
The trio quickly dressed and bulletproof hat body armor Liang pedal to the metal, police car, like playing the adrenaline, jump out …
At the same time, the mobile patrol group consisting of four squadron commander, Dorothy Wang Wei, also driven from the Yan’an Road to find the past. PTU forces as Hangzhou, they are always ready for such emergencies. 1:40, Chen L, Tang Guangren, Huang Chun were rushed to the airport highway roundabout, and mobile teams have been rushed to the Qiutao the road, driving in the lane from east to west. Has been working with the Council ‘s command center to keep in touch Tang Guangren eyes suddenly jumped into a license plate Zhejiang G. 3L966 black! Mazda! ! Pass! ! !
Turn around, catch up! When the suspect vehicle tens of meters of the West Hing Bridge toll booths, to increase the horsepower of the patrol car in one fell swoop than a black Mazda sedan. Police check! Rely on street parking! “It’s like suddenly wake up, black Mazda after a brake suddenly accelerated to escape, what more to patrol the front. Hit stop it! “Tangguang Ren and Huang Chun almost the same time cried out.
Chen Liang hold the steering wheel, police cars left front side of the grazing Mazda body right side. Loud bang squeak “tire friction sound, the two cars also stopped at the roadside.
The PTU players quickly get off loaded revolver bullets.
At this time, Mazda cab slowly opened, a man suddenly rushed out, Huang Chun a press down on the ground. At this point, Tang Guangren thrown already prepared telescopic batons, black Mazda rear seat on both sides of the glass has been crushing. Car of the three suspects in shock, eyes only for Liang hands of the support 92 police pistol dark muzzle.
“Police, do not move! Shuangshoubaotou!
At this point, the mobile teams rushed to the scene to reinforce the four suspects were on handcuffed. From the vehicle, with PTU team found the four machetes, 2 roll of paper tape, masked with black plaid masks, hats, a narcotic beverage bottle, as well as Wu looting items.
At present, four suspects have been Jinhua police away trial.
February 7, scientists cultivate a genetically modified goat produced goat milk contains the same with the spider silk protein, using goat spider silk woven fabric sturdy degree of Kevlar fiber used in bulletproof vests 4 times. In the laboratory, scientists goat spider silk and bio-engineering methods to cultivate human skin mixed together to obtain the artificial skin with bullet-proof ability.
“New Scientist” magazine reported: “bioengineered skin withstood bullets fired by the half-speed bombardment, however, its impact resistance of the existence of limit, the bullet to reach 329 meters per second at full speed, the bullet will penetrate the skin.” Dutch researcher Jia Lila – Yi Sadi, said the spider silk research program known as “329 meters of 2.6 grams per second”, named for the .22 caliber rifle bullet weight and speed. The goal of this study is designed to replace the spider silk protein keratin in human skin.
Study of spider silk production in the United States, Utah, and then spun in Korea, followed by Germany woven into fabric. The last step is to make bulletproof skin around the growth of a layer of the skin, the whole process lasted about five weeks. Yi Sadi, says the study science fiction become reality. Spider silk is used to war has a long history, Genghis Khan, once for all cavalry with spider silk vest to resist the enemy arrows are sent forth.
She said: “Imagine the use of spider silk made of a bulletproof vest, able to withstand captured live bullet impact and bullets – bullets is equivalent to the modern version of Genghis Khan era arrow. Now, let us then move forward one step further, Why only the manufacture of bullet-proof vest? Imagine spider silk protein to replace the keratin in the skin. about the tenacity of this protein with the skin. ”
Yi Sadi said: “also exists the possibility of spiders secrete spider silk genes into the human genome, to create a bullet-proof people. Sounds sci-fi? Maybe, but we believe that to allow this to create the idea of ??Superman as reality, the way will have bullet-proof performance spider silk together with cultivated skin. “Ballistic VestĀ have been for decades, but can bulletproof skin has been found in science fiction, the most famous example is Superman invulnerable superhero.
Three nuclear power a water culvert at 30 meters, the geological information on the 1st axis of the shield tunnel about 35 meters along the hole are strongly weathered, the weathering and the breeze of andesitic basalt. To ensure the safe and smooth shield tunneling, the tunnel section with a new Austrian tunnel method with advance support method of construction workers. The so-called New Austrian Tunneling Method, that is hollowed ground, leaving room for further shield advance of the construction process, which take the drainage works in the nuclear power is an epoch-making for the first time, this holds a lot of people sweat. However, for “invincible, to make progress,” the construction of the Iron Army, there is no more important than the early completion of the nuclear power plant. The face of half soil, half stone geological conditions, the project department of the shield first bedrock encountered along the upper range of the tunnel on both sides of the mud and soft soil reinforcement for high pressure jet, then the use of the bassoon studio program for the tunnel wall advanced support and protection of soil and stone to be a solid body, the use of “blasting excavation, lining shield,” the construction method, the formation of ?8000 mm diameter tunnel. At the same time promptly after the initial excavation shoring (including bolt, steel arch, steel wire mesh, shotcrete) construction, the initial support and advance support to form an integrated steel – concrete shell structure, in order to put a shield pieces of armor. But sometime in the new Austrian tunnel space to complete nearly ten meters (the longest distance NATM to 47 meters), has re-exploration, found in front of the shield there are 40 meters on the axis of weathered rock must be processed by experts demonstration and Design Institute agreed, the project caught red treatment used by the Department, and the use of fly ash into the hole after the cement, sand, water, and the right amount of admixture preparation of fast rigid slurry pressure injection catheter underwater resolve the solid side shield week series of moderate hardness problems. After a year of careful and painstaking hard work to complete the construction, for the shield to create the conditions out of its hole.
After the success of the new Austrian tunneling method, the shield in the shortest time was pushed to the air inside the tunnel. As the air to push the construction, the front shield without resistance, non-binding segment four weeks to control the deformation segment, segment fastening and construction difficulties grouting has become a focus. Project department did not give up, no ready-made construction specifications, find their own way, not the teacher, ask to practice. They guide and support the shield as forward-oriented, no-load advance and assembled pipe films, combined with millimeter precision control, and sand-filling in the tunnel, the segment from the tail of the shield machine, the staff of warehouse to with auxiliary gaskets shield tail segment with rail gap, combined with sand fill in the blank, control segment deformation. After pushing air from the tube sheet construction hole into the cement slurry grouting for reinforcement, the segment with the new Austrian tunneling gap between the fully dense fill. Hard work pays off, quick response in the construction of the Iron Army before stumbling block has been sent packing, the construction of nuclear power industry for the first time the shield off to a good start.
In order to protect the Chinese citizens in the Mekong River Basin and the legitimate rights and interests of navigation safety of life and property, No. 10 last month, Myanmar and Thailand in the old four-nation joint patrol the Mekong River for the first time law enforcement aspect has to track news reported. A golden waterway, the four countries combined law enforcement. Today, the Mekong River shipping order is gradually restored. This morning, CCTV correspondent on board the Chinese enforcement vessels patrolling off tired from the port of Yunnan, in the next few days following the joint patrol of law enforcement experience, the whole process.
Today, half past seven with three rounds of green flares launched, the correspondent law enforcement patrol boat ride from Port Yunnan sail off tired. After half an hour of sailing, has been pulled into the Mekong River between Laos and Myanmar leg. Boat down the river, the reporter left, Laos, Myanmar, the right hand side is. Enforcement vessels will have the channel along the Mekong River, sailing into Laos, Myanmar, Thailand, the border between the waters, which is the frequent cases of water law and order, that is, we are all familiar with the famous Golden Triangle.
Now up and down the Mekong heavy rain, which both sides of the mountain valley and the middle of the mist-shrouded valleys, and to see a lot of rocks and rapids. A feature of the Mekong waterway particularly sharp bends, which made for great sailing challenges. Since the last joint enforcement, the Mekong River Basin is to reproduce its vitality. 7 half-day has not been large bright, the merchant is not a lot of the habit of night, a beginning to see which merchant sailing in the channel, with the enforcement of the ship’s progress, a steady stream of merchant ships in the channel to see some of them appear, they go through law enforcement ship when the ship’s crew to the law enforcement patrol boat waved.
Mekong waterway is very complex, very poor natural conditions, many rapids, and are particularly vulnerable to stranding. The other is the waters of the Golden Triangle is also armed drug trafficking activities of arms smuggling is rampant, the ship is the frequent occurrence of attacks, so the officers and soldiers and police to participate in tasks that may be encountered for a number of specific emergency situation drills and to develop a more comprehensive plan. Reporters interviewed on the deck is the task of observation, a police guard, he was armed and wearing bullet-proof helmets, bullet-proof jackets there wearing knee, carrying light weapons. Reporters also asked to put housing in accordance with body armor, wear a helmet.
In this harsh environment, a bridge of boats in Los peacekeeping force of 45 officers and soldiers, remember exhortations fail in their mission, unite as one, accomplished peacekeeping missions, has been praised by foreign soldiers.
“Our main mission area is responsible for roads, bridges, airports construction, maintenance, board room to build other military and humanitarian missions.” Tang Xiangjun said foreign soldiers take the board room, you need to find a teacher, hands-on, little by little to teach, but they, people read the manual, it will install, and experience design unreasonable, but also directly in the construction of improvements.
A pontoon troops stationed in Los commander, military construction and installation squadron engineers Fan introduced the board room with the foreign country is not the same, steel, screw with than more. “In the beginning, 15 people take a three-room suites to use seven days, after trial and error, sum up, when the degree was stationed in Hyderabad, three room suites, four individuals will be able to take a day and a half finished.” Fan Jun said they had 30 people five days to create the nine sets of activities of the board to build a “multi-function engineering with Chinese speed.”
According to reports, the peacekeeping mission during the construction and installation squadron of officers and soldiers have fought in Hyderabad degrees, Muha Jie Rhea, Nyala international airport, the completion of the camp facilities, container ceiling, airport expansion, expansion of logistics bases and hospitals, construction of pollution treatment facilities more than 60 missions, built 36 sets of activities of the board, puts up a protective wall of nearly 2000 meters, pulling barbed wire set up on the ten thousand meters.
Peacekeeping mission in Darfur, Sudan, more than 200 days, a bridge of boats in Los completed peacekeeping troops well, and its high efficiency, unity and other fine work style has been widely praised by foreign soldiers. October 26, 2011, the United Nations and the African Union mission in Darfur will be personally awarded the Commander Patrick Rick Rockwell in a pontoon where the Chinese troops to the Sudan peacekeeping in Darfur and the engineering team, “United Nations Special Contribution Award “thanked China for the local engineering company made ??an outstanding contribution, a bridge of boats in Los 45 officers and men of all forces was awarded the United Nations Peace Medal.
Last week, several tribes in Jonglei Muller Noor and Dinka tribes armed invasion settlements, predatory animals, burning of villages, rob people, causing tremendous property damage and personal injury. Yesterday we received the latest information: ten thousand armed Nuer tribe had assembled, to be launched at the recent retaliatory action. Diametrically opposed forces of several parties, the conflict intensified.
Today morning, the Boer commander Serena Senior Operations mission area assigned inter-Chuan Guo, my colleagues and I conducted an immediate investigation into the Makuwajia. He said: “This task is very important that you be sure to investigate local government participation in the real intention of preventing conflict and the deployment of troops of the specific programs to facilitate United Nations action plan.”
Rena look so serious we deeply feel the pressure of sudden, we quickly prepared food and water, wear a helmet put on body armor, car starting.
Makuwajia from our camp, there are dozens of kilometers. Although not too far away, but the potholes along the uneven roads, on both sides of all the dense African jungle, but also through several tribes inhabited by Mueller, can be perilous. Road bumps and high-temperature heat quickly so we were sweating, constantly drink water to quench their thirst. To go through four checkpoints along the way, keep the military post of some government troops, some tribal army. After a checkpoint, the guards see that we are the United Nations personnel, both documents will look smooth rough release. But as the moment with them, I feel their eyes cautious and cold.
After nearly two hours of bumpy, and finally safe. We were split up, and soon gathered to participate in the local police to stop tribal conflict first-hand information on the successful completion of tasks.
Hindsight: Yes, ah, this experience was tough, but it is a rare experience in life. Thousands of miles away from the motherland, the land of Africa, mutual trust and support of his comrades to overcome all difficulties protection.
“Sniper training is very strict, one of our kits, including bullet-proof vests, helmets and other have 30 kg to 40 kg, and this is also the sniper rifle, 4.4 kilograms.” Sniper said, wearing camouflage nets today, but also peacetime training wear, because they have to learn to adapt to a variety of complex environments, in order to better fulfill its mandate.
“As a commando, everyone’s marksmanship is good, but to become a sniper, watch, or psychological.” Scene two snipers, one of whom had one eye exposed, while the other side of the police officer surnamed, is completely cover the face, even an interview, he also just opened a little bit the face of network. Side police officer said, in the “Black Panther Commandos”, the players according to their strengths play different roles, in which the advantage of not only the sniper marksmanship, also psychological.
As usual snipers are firing against training dummies, and sometimes psychological training in order that they would even be a “metamorphosis of the shooting,” that apple on his head for a sniper, and then another sniper to shoot, “that little training was indeed the psychological pressure, but at that time to believe in yourself, trust your marksmanship.”
Multimedia speaker classification according to different types have different results, let’s look at some common classification:
1 in accordance with Cabinet Material, a common plastic containers and wooden boxes;
(2) the number of points according to the speaker unit, a single speaker unit (full-band unit) and double (or triple) speaker unit (two or three-way);
3 divided by number of channels, two-channel stereo (2.0 type), dual-channel plus a subwoofer channel (two-point surround), four channels plus one subwoofer channel (four-point surround) and five channels plus a separate subwoofer channel (5.1 type) speakers, etc.;
4 horn structure of sub-units, ordinary speaker, flat speaker, aluminum speaker and so on.
Note: The unit has normal speaker diaphragm according to the points of different materials, such as the bass unit are: cone, wool pots, ballistic fabric pots, polypropylene pots, metal pots and other materials, metal dome tweeter, soft film dome, etc.;
5 points according to the computer output, a common interface (sound card output) speaker and USB speakers;
6 According to the PA within the external points to a powered speaker (amplifier built-in) and passive speakers (an external amplifier, high-end models, or only used with special requirements);
7 Price, is generally believed that the price per pair (excluding bass, after the same) to 200 yuan for ordinary speakers, the price of each of between 200 to 700 yuan for mid-range products, the price more than $ 700 the generally high-end products. However, the actual situation may be slightly different with this, which have the brand based on the product and actual performance may be;
8 by use of points, there are general purpose speaker, entertaining speaker uses (such as games, VCD, DVD, and music appreciation) and the professional use of the speaker (eg, MIDI production, music enthusiast to enjoy).
U.S. soldiers have made the ultimate next-generation helmet (known as enhanced combat helmet ECH), officially opened this year. Which contains within the carbon fiber helmet, this helmet outside the hard-soft, lightweight, made ??of ultra-high molecular weight polyethylene fibers. Which ballistic helmet manufacturer to reduce the weight by 20% than in the past. This material is made from composite materials developed by Honeywell, contains a phenolic resin material.
Nevertheless, a number of U.S. high-tech fiber business is continually developing, suppliers, designers hope to see more performance fiber products. One notable feature is the high performance and low cost. In the climax of this development, the United States is also eager for DuPont, the company began its protective material to provide a number of manufacturers of materials, from design to test samples to accurately assess the economic and practical value, the most important thing is to comply with U.S. military standard and non-military applications. As early as last year, the U.S. military held a spectacular new design and multi-purpose military equipment exhibition helmet.
U.S. media that such commercialization, low weight, low-cost, composite fiber materials, protective security products is unmatched. Apart from that, the U.S. Department of Defense requirements for munitions and a variety of multi-functional structure of body functions.
Although the world is changing, product innovation, but security is always the most important people, whether individuals, organizations, or aircraft, ships, cars or buildings, these security in the future will become a priority. U.S. war in Iraq and Afghanistan has been described, bullet-proof protective materials have become an important future goal of fiber development.
Police launched a police camps zhouxiang Center Open Day activities. In the afternoon, Zhouxiang Central Primary School 50 students lined up in the ten security team escorted by police into the center of great interest zhouxiang visited the “mystery” of the police camps.
First stop: the police, under the guidance of his uncle, the students visited the anti-drug exhibition. Students are the exhibition hall a door to attract all kinds of billboards. “Hey, really terrible drug!” Billboards on the body after taking drugs and a variety of symptoms appear one painful lesson for students to horror. “Before, I heard only in the textbooks is a crime of drug use, know today, drug use is no small harm!” The students watched and discussed with.
Second stop: the police led the students to police law enforcement equipment display area for the visit. Many students before on television, movies to see batons, body armor, shields, bullet-proof helmets, flashlights and other police equipment and interest to light. “The police uncle, hit people with batons future will hurt? ‘” Police aunt, body armor is what the material? “A problem for students who overwhelmed police. Police have to tell you and demonstrate the role of various types of equipment use, and allow interested students to wear body armor and equipment, experience “when the police” feeling.
Third stop: the students on the ground watching the “Global Net Project.” In the control center, the students eyes wide open staring at the screen, pleasantly surprised to see their school gates to monitor and dozens of major roads real. Police have also simulated the spot, “the police catch the thief,” the scene representation, and allow students to participate, so that students experience a sense of the police catch the thief.
Fourth Station: Students gathered in the playground, watch the special police uncle martial, shields and other simulation confrontational training exercise performance. SWAT valiant uncle, neat and effective action, the students won applause from time to time. Students say, can personally watch this show is really an eye-opener, especially for special police uncle’s ability to praise, for their pride.
