Based on the previous work, this paper analyses the reason for small self-excited vibration of the aerostatic x-y stage, which reduce the positioning accuracy. 摘要以前期研究工作為基礎，分析了氣浮式工作臺由于微小自激振動(dòng)的產(chǎn)生，而引起其定位精度劣化的內在原因。
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。
