排气时间 meaning in English
evacuation time
exhaust time
exhaustion time
period of exhaust
Examples
- Two . the individual output rises up owing to the special structure of the exhaust punch which may effectively shorten the exhaust time and reduce the number of exhaust times
二、提高单机产量：由于排气模芯的特殊构造，可有效缩短压制砖坯时的排气时间和排气次数，从而提高单机产量。 - Results : the new cesarean section had advantag es of shorter operation time and fart time , quickly temperature recovering , low recurrent rate , and better wound healing com pared with the traditional method ( p 0 . 01 )
结果：新式剖宫产术较传统剖宫产术手术时间短、排气时间早、体温恢复快、术后病率低、伤口愈合好(均p 0 . 05 ) 。 - Principal conclusions were drawn as the following : the non compatibility of pressure or velocity of the gas on both sides of the contact surface is the cause of the formation of shock wave ; the heating effect of reflective shock wave to driving gas during charging or exhausting process is the internal mechanism of peak oscillating effect , and all the factors that influence the formation and the running of the shock wave will influence the peak oscillating frequency , cooling effect
主要结论如下：热分离机内激波形成的原因是射气瞬间接触面两侧压力和速度不相容；峰值振荡效应的内在机制为反射激波对充气阶段的驱动气或低温排气的加热，凡是影响激波形成及运动的因素都将对峰值振荡频率、冷效应及热效应产生影响；当充、排气时间比为0 . 1763时，最佳射流激励频率出现在高阶峰值振荡频率上。 - The relations between the parameters of gas charging and exhausting , heat quantity through the shell of tube ( q ) , the length of the tube ( l ) , the ratio of gas charging time to gas exhausting time ( ) , the frequency of the jet flow ( f ) , the ratio of the expansion ( ) , the nature of thermal separator and the unsteady flow in the tube were established
建立了进、排气参数、管壁散热量（ q ） 、管长（ l ） 、充、排气时间比（ ） 、射流频率（ f ） 、膨胀比（ ）等参数与热分离机性能及管内非定常流动的关系，并分析了有关因素对热分离机性能的影响。
