【摘要】 本工作采用文献发表的临界参数实验值，对典型的十几种推算临界温度、临界压力和临界体积的方法进行了评价与考核，为工程技术人员快速准确的预测化合物的未知临界参数提供了参考依据。通过对临界温度推算模型的研究，给出了考核结果和推荐使用的方法。更多还原

【Abstract】 More than ten typoical estimation methods for critical temperature,pressure and volumes were tested and commented in this work using experimental critical data in literature.A reference hasis is provided for engheering technicians to select appropriate methods to accurately estimate the unknown critical properties of organic substances. The test result and methods recommended are presented by studying the estimation models for critical temperation.更多还原
