例句與用法

1. Based on a two - dimension model for the flow field in catalytic converter , the flow field and pressure loss in catalytic converter with different inlet headers are simulated
   摘要利用催化轉(zhuǎn)化器流場(chǎng)的二維模型對(duì)多種入口管結(jié)構(gòu)的催化轉(zhuǎn)化器流動(dòng)分布和壓力損失進(jìn)行了數(shù)值計(jì)算，并提出一種組合型入口管。
2. Hot air cnters into stirring and crushing and drying chamber from the bottom of drier with suitable atomizing speed . it exerts strong shearing , blowing , floating and rotating effect to raw material . therefore raw material is granulated through centrifuge , shearing , impacting and friction effect
   熱空氣由入口管以適宜的進(jìn)風(fēng)速度從干燥機(jī)底部旋轉(zhuǎn)進(jìn)入攪拌粉碎干燥室，對(duì)物料產(chǎn)生強(qiáng)烈的剪切、吹浮、旋轉(zhuǎn)作用。
3. The experimental and simulation results show that using the improved structure of inlet header can greatly improve flow uniformity , decrease pressure loss , enhance the efficiency of twc , attribute to prolonging the service life of the machine , and lessen the power decrease caused by twc , but the light - off time of twc is retarded
   通過模擬與試驗(yàn)表明，與常規(guī)結(jié)構(gòu)催化轉(zhuǎn)化器相比，組合型入口管可明顯改善流動(dòng)均勻性，降低壓力損失約1 / 4 ，提高催化轉(zhuǎn)化器效率，延長(zhǎng)使用壽命，減小對(duì)發(fā)動(dòng)機(jī)動(dòng)力性的影響，但起燃變慢。
