spark formation

Radius is inversely proportional to spark resistance, so smaller spark resistance is propitious to the formation of discharging current.

火花电阻与火花半径成反比，说明较小的火花电阻有利于主放电的进行。

With increasing concentration of NaOH in the solution of the anodizing, the time and voltage of spark formation decrease and particle, porosity, thickness of anodic oxide film become smaller.

阳极氧化过程中，随着NaOH浓度的升高，出现电火花的时间缩短，出现电火花的电压值降低，阳极化膜表面的颗粒变小、孔隙率减小，膜层厚度减小；

In this paper, in a spark ignition injection hydrogen-fueled engine, the combustion process of hydrogen-air mixture and the mechanism of NOx formation are expounded on basis of the theory of combustion and chemical dynamics. At last, the combustion of low NOx formation is emphatically described.

本文从燃烧理论和化学动力学角度分析了氢喷射火花点火氢发动机中氢空气混合气的燃烧及其NOx的形成，并着重描述了低NOx燃烧。
