in the study, the disease of airflow rate caused by frost layer is taken in account. thenumerical results are available.
在研究中考虑了霜层阻力引起风量下降这一因素,计算结果具有一定的实际意义。
the limitation of the budryk's method(static analysis method), which ignores the effect of the length and the initial airflow rate of a parallel airway on airflow reversal, is pointed out.
指出了布德雷克(静态分析)法的局限之处,即没有正确认识到巷道长度及初始风速对风流逆转的影响;
this study aimed to analyze the effects on aeration by the difference in temperature between grain and air, airflow rate and opportunity of operation.
本文就机械通风作业中的温差、单位通风量以及通风时机的把握对通风效果的影响进行了分析和讨论。
conclusion maximum phonation time, the mean airflow rate and ratio of phonation volume to vital capacity can be used as indicator in clinical application.
