DL－32／16型多路时间间隔测量仪及其应用

MODEL DL-32 MULTICHRONOMETER AND ITS APPLICATIONS

基于模拟内插原理，研制了一种精密多路时间间隔测量仪。该仪器有一个公共起始通道和３２或１６路停止通道，测时范围５０ｎｓ～８２０ｍｓ，分辨力１ｎｓ，精度优于±５ｎｓ。由于采用了内部微处理器，仪器具有内部自检、通道识别、差错指示和测量数据自动显示，打印、处理及掉电保护等功能，并能给出多次测量的平均值、最大值和最小值。实验测量了Ｔ／Γ炸药的爆速和钨合金中的冲击波速度，得到满意的结果。

Based on the principle of analogous interpolation,a precise multichronometer hasbeen developed.It has one common start channel and 32 or 16 individual stop channels,each with50ns～820ms range,1ns resolution and an accuracy better than ±5ns.Controlled by a built-inmicrocomputer,it features self test,trigger recognition, error indication and automatic data display/print.In multi-measurement mode,it can provide the maximum,minimum and average values.Experimental measurements of detonation velocity in T/Γexplosive and shock wave velocity in93W alloy have been succesfully carried out with satisfactory results.
