| 摘 要： | 本文通过实验发现在气压传动中，气阀开启的瞬间通过气阀的气体流量与气阀开启时间的长短有关，而非通常认为的一个常数，通过气阀的最大气流量约为稳态流量的2倍。据此，本文认为在气阀开启瞬间计算气流量地应对稳定、绝热、可压缩气体的标准方程加以修正。

| Abstract: | In our pneumatic experiment,it was found that the flow rate of passing a pneumatic valve is not constant as usual and related with the valve opening du- ration during the transient of valve opening.The maximum flow rate of pas- sing the valve is about two times larger than the flow rate of steady state.The- refore,the standard formulas for steady state,adiabatic,compressible flow should be corrected while calculating the flow rate of the transient of valve opening. |
