The research of the rheidity of material indicates that low temperature thermal treatment of slurried coal can alter the rheidity of slurry.

料流变性的研究表，煤的低温热处理可改变煤的流变性。

Some different metamorphic grade coals surface character was changed through the hypothermia thermal transnature in order to influnce the rheidity of coal-oil-water ternary material.

不同变质程度的煤采用低温热改质,使煤表面的性质发生变化,从而影响煤油水三元料的流变性。
