当有机物在进行炭化作用的时侯,其本身物理及化学性质即发生变化。但有机物一般与某种矿物不同,不同的原始物质所具有不同物理及化学性质即随温度、压力、时间的变化而在不断变化着。因此在决定煤的炭化程度时就利用这类性质的变化。在这里面一般以镜质组反射率为测定炭化程度的标准参数。 As organic matter undergoes carbonization, its physical and chemical properties change. However, organic matter is generally different from a certain mineral, and the different physical and chemical properties of different original substances are constantly changing with temperature, pressure and time. Therefore, when determining the degree of carbonization of coal to take advantage of such changes in nature. In this general vitrinite reflectance for the determination of the degree of carbonization of the standard parameters.
