Staff reporter Li TianShu On August 17, reporters came into the bird nest and watched a match. The evening before that day, " fleet-footed runner's competition " that is performed here In men's 100 meters final, Jamaican player Bolt is with the achievement of inconceivable 9 seconds 69, have brought one hectometre of limit of 70 into for 9 seconds the mankind for the first time. In this huge nest woven with steel construction, 100,000 audiences gather and appreciate the tournament, have not felt crowded and felt a pain. This is because designers of the bird nest have used the hydromechanical principle, has carried on the simulation of heat comfortableness, wind comfortableness and analyzed the experiment to the auditorium, have paid optimizing too in ventilating facilities. Where no matter the audience sits, can enjoy the mere wind naturally. A lot of international top application of building technology, make venue become light spot that High-Tech result concentrate, also become the focus that people pay close attention to. Why does water cube become Promised Land " freestyle player " Swimmers such as Philps,etc. break world record in bluish waves intermediate frequency, has turned water cube into the assembly line of the world record. People look for the secret on water cube too while affirming player's achievement. OK becomes water cube " The magic cube " (used after an attribute)? It is a water temperature at first. Cubic China chief designer Zhao XiaoJun says, unites the regulation water according to international swimming, the temperature of the swimming pool, at ��25 - 27 ��, and cubic water temperature of water has been controlled at ��26.5 - 26.9 �� accurately all the time. Temperature high in low viscosity of water, athlete maximum to swim speed than can improve 2.26% at 25 �� at 27 ��. Water cube controls the water temperature to unite the upper limit allowed in international swimming, can help athletes to create the good result. Secondly, water cubic water wants the craft of regulating through filtering, ozone sterilizing, active charcoal absorbing, sour alkalinity etc. in front of injecting the swimming pool into, and remove all residual ozone. This not only can remove the peculiar smell effectively, make water of the pool clean and transparent and can also make athletes feel comfortable in water. Some indexes of cubic water quality of water have even exceeded the drinking water standard. In addition, water is cubic to reach 3 meters deeply. Unite stipulating, the depth of swimming pool of the competition is qualified in 2 meter to 3 meter according to international swimming. The deeper water is, the smaller resistance the ones that were produced at the time of the perturbation above water are, the faster athletes' speed is. There is cubic lane of water too " The arcane truth " . The expert introduces, the outlet of both sides of swimming pool can arrange and go on a tour water overflowing in the swimming match quietly fast, isolating the rope in the lane adopts the material that can absorb repercussions most to be made, this makes the ripples produced at the time of the match are seldom returned to back to the pool wall of swimming. Zhao XiaoJun says, there are some humanized designs, such as water cube is widened very much, the auditorium is far away from the competition area, oppressing the sense to lighten greatly of the players. Influence the achievement in order to prevent athlete's body from being cold, all there is geothermal heating on the ground of the area of competition, the foot can not be cold either that athletes only burn. "It is the result that athletes strive hard that the world record is frequent and is broken, there is not inevitable relation with venues. The designer makes every effort to accomplish in each detail best, create the best match environment for athlete. " Make " calm place " The badminton match is most afraid of " The wind " Project. In the gymnasium of Beijing University of Technology, the badminton player is lifting and snatching a gold medal in the World War. This venue has solved the problem of the air conditioner wind well. At the end of 2005, when the badminton team of our country participates in the 14th World Badminton Championship, team members complain, do not know from which direction the wind is blown This is because this venue is iced the alley and reconstructed temporarily, open the air conditioner big in the hall at the time of the competition, the irregular change of wind direction, the course of action becomes difficult to master. The weight of the badminton is 5.5 grams, especially easy to influenced by wind-force to change direction. The wind speed of match of badminton can't be greater than 0.2 meters per second. Someone joke no accord with the intersection of badminton and professional venue of match nearly in the world at present. Should make a competition area not relatively windy, it is really too difficult. The intersection of Beijing University of Technology and gymnasium to transform venue too, it must turn on the air conditioner when being hot. How could make " The calm place " ? Beijing University of Technology the intersection of gymnasium and temporary ZongLin Qi, Deputy Manager of facility, say according to regular to design, blow wind next time adopt, it is certain to produce some vortex air current in the air of upper strata, compare with comparable to exerting a tremendous influencing. Venue of us change blow way, have, blow last time wind. Air current from the following to move forward up bit by bit cold air up, push to, answer the intersection of draught and position, then the wind circulates the hot wind out, comes inside cooling, blowing to venues through going back. For solve, down, blow the technological difficult point, air conditioner installation until audience hold the chair scientific research personnel. At the time of the competition, the air conditioning of the air conditioner blows from this duck eye of 13 centimetres in diameter out. Every air conditioner produce the intersection of wind and hole, install different blade of angle, during blowing out to disperse all around wind also. Such design is not only free of wind one while guaranteeing the intersection of athlete and match, give play to the best sports level, still can improve the comfortableness of the auditorium. It is reported, while taking the chair, have held more than 9100 air outlets in more than 7500. Originally, gymnasium air volume of giving per hour 748,000, every individual 99 cubic meters in air volume of handing over for one hour on average. Such big air volume of giving, blow, come out from several draught that concentrate on, wind speed sure greatly. In order to solve this problem, the designer expands the area of the draught, reduce the wind speed. Block the diving board and the air wall as the saying goes, the cartridge does not have the eyes. Though Olympic players are all sharpshooters, the sharpshooter is heavy while losing the level. In 2004 Athens Olympics men's 50 meters rifle final, the last shot of American player Emmons, miss the target in shooting practice and make in others' target location. People while saying with feeling the result is changeable, see safety factor in the shooting competition too. It causes rebounding or pierces on the building to hit after in order to prevent the bullet from missing the target in shooting practice, cause unexpected injury to athlete and other personnel, shooting hall in the area of open-air shooting installation polylith straggly to arrange to block the diving board. Can these guards block the impact of the bullet? Building a chief of the office, Beijing Shooting range hall chief designer Qi Bin of research institute says in architectural design of Tsing-Hua University, each it blocks diving boards to be to insert whom 6 millimetres of steel plates commit in the middle of the 2.5 centimetre thick plank by two piece. The wooden material can prevent ricochets, the middle stencil plate is very hard, can prevent being hit through. In order to verify this kind " Sandwich " Actual effect to block diving board, project side ask national shooter's combat exercise specially still. In the experiment, block the test that the diving board stands various competitions such as air rifle. In shooting venues, athletes wear the thick match clothes, the audience wears the frivolous summer clothes, is it the two and room of place one how? Qi Bin says, the venue designer is in the athlete location Have made a set of air conditioner devices with two draughts on top of the front of the land. When it runs, will form the air wall that can not see, feel together. This air?
