而砂土的毛细水上升高度不受冻融作用的影响。
Mining industry: metal melting (transportation and circulation of electrolyte); washing of liquid waste.

If its melting point were lowered by further degradation, its molecular weight would also be so lowered that it would not remain in the circulation long enough to have any effect at all.
如果因为进一步的退化它的熔点降低了，它的分子量也会降低，以至于它完全不会再流通中仍然有足够长的效果。
