| 摘 要： | 本文依据质点动力学和一维可压缩流体动力学原理，利用无限大容器的出流结果，在适当的简化假设基础上，建立了固体发动机切割分离泄压过程的数学模型，并对泄压过程和分离后的状态变化进行预测．通过比对分析试验容器的理论和试验结果，证明本文方法的误差在15％以内。

| Abstract: | In this paper, the mathematical model of pressure leak process for solid motor being cut off is estab- lished, according to particle dynamics and 1- D compressible flow hydrokinetics. Also, the outflow formula for infi- nite vessel and some suitable predigesting hypothesis are used to forecast the pressure leak process and flight state changes. It is proved that error of the paper's method is less than 15% comparing theory results with test ones. |
