First supposes the correlation coefficient that droplet back and forth moves, and the fluid reversibility have the direct ratio, and additional structures affect fluid reversibility. In order to confirm the supposition, this research develops one set method, Particles position distribution, uses probability statistics, linear algebra to describes and quantitative analyze position distribution of particles in the droplet. Uses the Particle position distribution analytic method statistics particle position variation in addition the situation, makes the particle position probability distribution the transformation matrix, describes under the different initial condition by the system overhead construction the particle position distribution result, and analysis result and it’s the correlation coefficient. This research knew by the experimental result, the correlation coefficient that droplet back and forth moves, and the fluid reversibility have the direct ratio. And utilize statistical method to develop one set method to describes and quantitative analyze position distribution of particles in the droplet; learn from the experiment and analytical method, additional structure will reduce flow reversibly of droplet.
