| 摘 要： | 通过对垂直发射燃气排导位置中压力室与排气道的声场分析，非声不稳定性被认定为是声振的零阶振模，从而使非声问题可以利用现在成熟的声理论去分析。展示了声与非声同时存在的实验现象并对实验结果进行了定性分析。

| Abstract: | The present paper describes the acoustic field in the pressure room and uptake of the VLS. It enables one to apply the available information on acoustic analysis in attempting to understand the nonacoustic problem.The acoustic and nonacoustic experiment data in VLS are presented and simply compared. |
