气枪在水下产生地震初始脉冲的形状主要取决于气枪排气口的大小和极限截面积,取决于进入水中的排气速度,气体压力,气室容积和排入水中的空气体积,如果一支特殊设计的气枪在相同气压和气室容积下工作,预期产生的初始脉冲形状是可重复的,改变气室的充气压力,除改变初始脉冲的振幅外,对初始脉冲的持续时间没有明显的影响。
The shape of the initial pulse of an airborne gun that produces an earthquake depends primarily on the size and ultimate cross-sectional area of the air-gun vent, depending on the velocity of the exhaust entering the water, the pressure of the gas, the volume of the chamber, and the volume of air discharged into the water. Specially designed air guns operate at the same air pressure and chamber volume. The initial pulse shape expected to occur is repeatable. Changing the air pocket inflation pressure has no significant effect on the duration of the initial pulse, except for changing the initial pulse amplitude.
