１绪言在煤的软化熔融状态下所观察到的各种性质（粘结性、流动性和膨胀性），来自于煤的化学结构、骨架结构的热变化，为进行软化熔融过程的动力学解析，应将分子结构参数与上述诸性质建立关系。所谓软化熔融，是固体的煤处于液态化的一种现象，而且该液体、固体的量与性... INTRODUCTION The various properties (cohesiveness, fluidity and expansibility) observed in the softened and melted state of coal come from the chemical structure of the coal, the thermal changes in the framework structure, and the kinetic analysis for the softening and melting process , Molecular structure parameters should be related to the above properties. The so-called softening and melting, solid coal is liquefied in a phenomenon, and the liquid, the amount of solids and ...
