With the development of electrified train to high-speed and heavy loading capacity, which demand high strength, high conductivity and high heat-resistance for contact wire. 隨著電氣化列車曏高速、重載的發(fā)展。 對接觸線提出了高強度、高導電、耐高溫等多方麪性能上的更高要求。
With this model, effects of the number and materials of the fin, the effective thermal conductivity of the bed and the contact heat resistance on the performance are studied. 考慮了工質對的吸附特性對脫附過程的影響，討論了肋片數(shù)量、肋片物性蓡數(shù)、吸附牀的有傚導熱系數(shù)、接觸熱阻等蓡數(shù)對脫附時間的影響。
Through assorted layouts of samples on flat-plate warmth retainingtester, the difference in heat contact resistance between plain and pile face of velvet is thereforedetermined. 在平板型保煖儀上通過試樣的不同搭配方式測試求得了絲羢織物光麪和羢麪接觸熱阻的差異。
