| 摘 要： | 通过１４件高温高压实验样品及其原样的电子顺磁共振研究，论述了温度、压力、应力、应变速率和应变强度等是影响变形煤化学结构演化的重要因素，但在不同的煤级中和不同的实验条件下，各因素所起的作用是不同的。变形煤ＥＰＲ参数的演化与镜质组反射率的变化密切相关，并且具有较好的规律性。说明镜质组反射率是煤化学结构演化的外在反映，是煤田构造研究中极为重要的标志物之一。

| Abstract: | It is expounded that temperature, confining pressure, stress, strain rate and strain strength are important controlling factors to evolution of chemical structures of deformed coals through the study of electron paramagnetic resonance of 14 deformed coals under high temperature and confining pressure and their intial samples. The action of each of the factors is not the same in different rank coals and under different experimental conditions. Evolution of EPR parameters of deformed coals has a direct bearing on varying of vitrinite reflectance and, there are good regularity between them.This illustrates that vitrinite reflectance is a apparent appearance of evolution of coal chemical structures. Therefore, vitrinite reflectance of coal is one of the most important indicators to research coalfield structure. |
