点火回路电感的计算机辅助测量

Estimation of the Circuit Inductance Distribution

点火回路中各部分的电感都为nH量级，并且其体积往往很小，要准确的测量其各部分电感的大小具有很大的难度。本文介绍了一种利用计算机辅助分析回路电感的方法，通过建立计算机仿真模型，利用放电时回路中各个参考点之间的电压波形的差异，通过改变测试参考点，比较实测电压波形与仿真电压波形来得到点火回路中电感的分布情况。

It＇s difficult to measure the circuit inductance exactly because it is ＂nil＂ level.This paper describes a method to measure the distribution of the circuit inductance with help of the computer, it obtains the distribution by comparing the measured wave with the simulated wave. It finds out that the circuit inductance mainly fasten on the detonator-plug.
