A parameter sensitive to thermal evolution, e. g. vitrinite reflectance, is measured on a certain number of samples from a well.
对热演化敏感的参数，例如，镜质体反射率，可从一口井的一定数量岩样进行测定。
This method has a practical significance if it is used to determine palaeogeotherm in the marine and pre-Devonian strata which are lacking in vitrinite.
在缺乏镜质体的海相地层和前泥盆纪地层中，应用该方法分析古地温更具有实际意义。
There is a definite relation between fuel ratio and vitrinite reflectance. The observation to pyrolysed char particles by SEM has shown that the char morphology is greatly influenced…
