The results show that the realizing flux-wall to guid transfer form of metal droplet is a prerequisite to the fine usability of double coating electrode.
结果表明：双层药皮焊条熔滴实现渣壁过渡形态，是焊条良好工艺性的前提条件；

However, a silica cage around each droplet prevents them from binding together and turning back into water, making the substance into a fine powder instead.
但是，包围每滴水的硅笼阻止它们结合在一起回复为水，而使这种物质成为细粉。

Researches indicate that the increase of the work pressure of fine water mist system can decrease particle size of water droplet of fine water mist and enhance the efficiency of fire-extinguishing.
