众所周知,温度、压力和时间是影响煤变质的重要因素。为了探索这些因素对煤变质的作用,我们利用X射线衍射仪等手段对煤的芳香核进行了结构测定(其原理和方法见本刊1980年第2期“煤的X射线分析”一文—编者)。首先单独研究温度或压力分别对煤结构的影响,然后再同时进行温度和压力复合因素的实验。为了结合实际,还研究 As we all know, temperature, pressure and time are important factors that affect coal metamorphism. In order to explore the effect of these factors on coal metamorphism, we used X-ray diffraction and other means to measure the structure of the aromatic nucleus of coal (for the principle and method, see the article “X-ray Analysis of Coal” ). First of all, the effect of temperature or pressure on the coal structure should be researched separately, and then experiments of temperature and pressure compounding factors should be carried out at the same time. In order to combine reality, but also research
