采用高速照相机记录火焰传播过程，并运用ProAnalyst软件分别对微乳化柴油的主火焰高度和闪火焰传播速度进行了测量和追踪分析。结果表明：各时刻的微乳化柴油主火焰均不是连续的，呈现“跳跃式”传播，并且主火焰的最大高度显著小于-10PD 的主火焰最大高度；微乳化柴油火焰传播的平均速度以及最大瞬时速度均远小于-10PD ，而 HS -10火焰传播的平均速度以及最大瞬时速度在3种不同含水量的微乳化柴油中也均为最小。微乳化柴油的阻燃防火性能明显优于-10PD 的主要原因是其中的水分对火焰燃烧产生了较强的抑制作用。

High - speed camera is used to record the process of flame propagation .In addition ,height of main flame and spreading speed of flash flame are measured and analyzed respectively by ProAnalyst software .The results show that main flame is not continuous at every moment ,it spreads ”jump” and also the maximum height of main flame is lower markedly than that of - 10PD ;the average speed and the maximum instantaneous speed of flame propagation are also much less than that of -10PD and that of HS -10 is the minimal in several kinds of micro - emulsified diesel .Flame - retardant and fire resistant characteristic of micro - emulsified diesel is obviously better than that of - 10PD because water has a strong in-hibitory effect on flame .
