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.

对几种不程度的煤采用低温热改,使煤表的性发生化,从而影响煤油水浆的流性。

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

对浆流性的研究表明，成浆煤的低温热处理可以改煤浆的流性。
