燃氣式無排氣孔的裝飾性房間加熱器用無孔火箱外殼Using detailed computer simulations, its designers have arranged its orientation and aerodynamic exterior to accelerate the gale - force winds that blow over the pole and channel them underneath the station
通過嚴密復雜的電腦模擬，設計師安排設計建築的方位和其空氣動力學外殼，讓強風加速吹過鋼筋柱使風力轉移到基地之下。The porous diffusion type silencer is widely used to reduce the air flow noise because of its small volume and high noise attenuating ability. the out case of the silencer plays a very important role in reducing noise. the effect of the hole ' s shape, diameter and the distance between neighboring holes as well as the matchup between the case and the sound absorbing material tube are investigated experimentally. the relation between the out - flow noise and the gas velocity distribution is carefully studied for two different kinds of matchup between the case and the sound absorbing material tube. some useful results are gotten, which may be valuable to the design of the silencer
多孔擴散型消聲器由於其體積小、消聲性能高而廣泛應用到排氣噪聲的降低上，其外殼對消聲器的消聲性能具有重要作用.本文對此類消聲器外殼的孔型、孔徑和孔距以及外殼同消聲材料的配合方面進行了細致的實驗研究，特別對外殼與消聲材料的配合與其排放噪聲以及外部流場之間的關系進行了探討，得到了一些有用的結論，對消聲器性能的提高具有一定指導意義。There is no air between the wire and hull to increase the dimension for quick heat transpiring and decrease the rising of wire temperature. the junction is combined from two directions thus to double the contact dimension and decrease the temperature of wire and junctions
