I have carried out a research on mesoscopic thermo-fluid dynamics in the vicinity of the macroscopic contact line of the spreading droplet with deformation. Major achievements during the present study are listed as follows;(1) precise detection of the precursor film ahead the macroscopic contact line(2) three-dimensional reconstruction of particles suspended in the droplet spreading on the substrate(3) effect of surface roughness/texture upon the movement of macroscopic contact line and upon the particle behaviors, and(4) control of particle behaviors in the vicinity of the macroscopic contact line.

我已经对散布液滴的宏观接触线附近的介观热动力学进行了研究。本研究中的主要成就如下：（1）对前方膜的精确检测（2）悬挂在液滴散布中的颗粒（3）表面粗糙度/纹理对粒子范围内的粒子运动和（4）对粒子的行为的影响的颗粒的三维重建（3） 线。
