Recoilenergy measuring system of a underwater launcher is formed by means of horizontal recoil device, electromagnetic velocity sensor, measuring amplifier, transient waveform recorder and computer.
Because of the light mass, the recoil effect is strong after the particle is emitted, so the recoil effect is must taken into account to maintain the energy balance.
由于轻核质量轻,发射粒子后反冲效应很强,理论计算中还严格考虑了反冲效应的影响,从而保证了能量守恒。

A theorem on kinetic energy for variable mass-point and formula of work of recoil internal forces are given and the reason of soft-rope query is discussed.
