用激波速度法比较不同电嘴的放电性能

COMPARISON BETWEEN THE DISCHARGE PERFORMANCES OF VARIOUS SEMICONDUCTOR SPARK PLUGS ACCORDING TO SHOCK PROPAGATION VELOCITY

本文介绍了用高速照相机结合纹影仪录取高能电嘴放电时产生的激波传播过程的试验方法,并根据录取的激波半径和时间的关系,比较了不同电嘴的放电性能。

In present paper an experimental method recording the propagation process of a shock which formed at the discharge of a semiconductor spark plug is described, and according to the curves of shock radius versus time the discharge performances of the various spark plugs are compared.
