<正>经各种条件下的全息照片的定性分析和采用计算机数字图像处理的定量分析，得出了喷雾场的粒子分布情况不同于传统观点所认为的分布情况，并基于液体破碎理论进行了雾化机理的分析；讨论了喷射时间、气缸背压、喷射压力、喷油嘴结构对喷雾特性的影响。

By way of the qualitative analysis of holograms and the quantitative analysis of computer digital image processed holograms under all kinds of conditions, the author has gained a droplet distribution of spray field which is different from traditional points and has analysed atomisation mechanism based on the liquid breaking theory. Injection time, pressure in the container, injection pressure and injector construction affect the spray characteristics.
