| 摘 要： | 给出定常一维等熵流的临界流量(最大流量)发生在喉部马赫数(Ma)为1时的一种新的证明.它克服了现有证明方法中或对流体性质制限的局限性,或避免了现有方法中所用基本方程求导的不协调性,因而具有明显的优点.

| Abstract: | There are two methods to demonstrate the critical flow rate of one-dimensional steady isentropic flow when Mach number is one at the throat of nozzle.However,the first one is restricted to the ideal gases with constant specific heat,and the second is based on the incorrect equations.A simple,concise,and rigid method based on the isentropic and adiabatic energy equations to prove the condition of critical flowrate for one dimensional isentropic flow is given in the paper. |

| Keywords: | one dimensional isentropic flow critical flow rate Mach number |
