Ceramic material had better performance than steel and copper and the shorter the stack, the lower the initial temperature for oscillation. 而從熱聲振動(dòng)的方式來(lái)看，強制振動(dòng)比自激振動(dòng)具有更低的起振溫度。
In the regenerative liquid propellant gun,the coupling oscillation of the fluid sys-tem in the reservoir including free vibration and forced vibration may be formed. 在再生式液體發(fā)射藥火炮中，貯液室流體系統可能發(fā)生由自激振動(dòng)與強迫振動(dòng)構成的耦合振蕩，在噴射結束期很可能形成共振。
