7.1 前言冲击运动的测量与振动测量不同,有几个特殊的要求。冲击测量应用于各种专题场合,包括大地振动,导弹的撞击,试验件下落的突然减速以及火工品爆炸所引起的瞬时振动等等。这些场合对测量都有一个必须满足的特殊要求,以便给出准确的测量结果。在2.3章所叙述的基本特性这里仍然适用,然而对所用的仪表的特性必须给予特别的注意,例如幅 7.1 Introduction Impact measurement and vibration measurements, there are several special requirements. Impact measurements should be applied to a variety of topics, including earth vibrations, missile impact, sudden deceleration of test pieces, and transient vibrations caused by explosive explosions. These occasions have a special requirement that must be met in the measurement, in order to give the accurate measurement result. The basic features described in chapter 2.3 still apply here, but special attention must be paid to the characteristics of the instrument used, for example
