摘要
在科学研究和工业生产中,需要精确测量各种物理参量.如重量、长度、速度、角度、体积、压力等,对于测量正常物体的运动速度,一般情况下比较容易求得.但是,如果是求取运动物体的瞬间速度,如抛出物体或自由落体的瞬间速度、汽车座椅受冲击时的瞬时速度等相对较难,目前国内尚无此测量仪器问世.本文主要叙述运动物体的瞬间速度测量原理和设计制作技术.
In scientific research and industrial production,accurate measurement of various physical parameters is often required. Such as weight,length,speed,angle,volume,pressure,and so on. For measuring the normal speed of the normal object,the general situation is relatively easy to obtain. But if it is to calculate the instantaneous speed of moving objects,such as throwing out the instantaneous speed of an object,or a free fall,car seat by the impact of the instantaneous velocity and so on,it is more difficult. At present, there is no such measuring instruments available in china. This paper mainly describes the principle of measuring the instantaneous velocity of moving objects and the design and manufacture technology.
