In this paper, the moving law of inside and outside interface of the liquid in the early phase droved by shock wave, the interaction between shock wave and fluid film and the interaction between shock wave and droplet were studied experimentally. The research stresses on the change of the detonation product actuation liquid medium interface and the outer boundary.Generalized analysis the experimental data of various parts, we can discover three rules as follows: firstly, the detonation product drives liquid movement in air and the outer boundary of liquid sheet turns to be stripped and thinning layer-by-layer and changes into water films. Secondly, The water film has the distortion under the shock wave function. And the combined action of the transmission shock wave and reflected wave's causes the water film to break and have the atomization. When water film thickness is certain, the water film distortion time increases along with the shock wave strength reduces, But when the shock wave strength is certain, the water film break time increases along with the water film thickness. Thirdly, the different bubble displays the different deformation, fragmentation and the atomization under the same condition's shock wave. The aviation kerosene's deformation, fragmentation and the atomization is easier than the 0# diesel oil.Moreover, we may also obtain the following conclusions: the configuration of the liquid link staveing and mixing process's surface change have certain similar rules: the similar rules of the anomalous shape's fractal and the mixing zone's variation along with time. The results indicated that under the same intensity waves, the temperature of ethyl alcohol rose quickly than the water's, and the ethyl alcohol is easier to vaporize.
