This article is devoted to clarifying the mechanism of reactive wetting and summarizing the change of wetting force of Sn-based solder and the morphology of the interfacial structure by changing the type of alloying elements added to the solder,experimental temperature and metal coating on Cu substrate.

Progress in the research of wettability reversal mechanism;

To counter interfacial adsorption and wettability reversal of the reverse wetting agent, and the features of mixed wetting in the limestone oil reservoir of this block, laboratory research is done on effect evaluation of oil reservoir core by water drive and EOR method of reverse wetting agent.

Study on boundary light reflection from curved liquid surface by the wetting rod;

When a collimated laser beam illumines the sunk curved liquid surface by two parallel wetting plate,the special reflective patterns,which correspond to the boundary light reflection,can be produced.
