中文摘要：

对液滴撞击水平固体表面的现象及特性进行了可视化实验研究，并对影响液滴撞击的参数进行了研究。实验工质是蒸馏水。重点是定性和定量测定这些参数对液滴撞击后铺展过程的影响。实验结果表明：固体表面的润湿性和表面粗糙度对液滴铺展过程的后面阶段有很大的影响，液滴的大小的影响比较小。

英文摘要：

Visual experiments were conducted for studying the phenomena and behaviors of the droplet impacted on the horizontal solid surface. The effects of the impact parameters on the droplet impacting were studied. The experimental medium was distilled water. This paper focused in the qualitative and quantitative determination of the influence of these parameters on the droplet spreading after impact. The results showed that the surface wettability and surface roughness had a strong influence on the spreading of droplet in the later stages of the process. The size of droplet had little influence on the process.
