引言 电磁粒子速度计方法最初应用在炸药内爆轰参数的粒子速度测量。以后又应用于惰性介质和岩石。最近,该方法发展为解决多种问题。这方法应用在炸药内的难点是要建立一个强磁场,费用不能太贵。有两种方法,一种为电磁铁,另一为Helmholtz线圈。前者炸药只能限制在φ50 Introduction The electromagnetic particle velocity meter method was originally used for the particle velocity measurement of detonation parameters in explosives. Later applied to inert media and rocks. Recently, the method has evolved to solve a variety of problems. The difficulty of applying this method to explosives is to create a strong magnetic field that can not be expensive. There are two ways, one for the electromagnet and the other for the Helmholtz coil. The former explosive can only be limited to φ50
