近来很多重要工业产品的制备过程都是在高压下实现的,因此,也就加强了相应的研究工作。近年来发表了专门阐释应用高压的评论性的文章和专著,这就表示已引起了人们对这方面的重视。高压下的研究工作所观察到的某些现象,在寻常条件下往往是很难想象的。例如,压缩溶液的蒸发,气体混合物的分层现象等等。这使我们不得不回忆起恩格斯曾经说过的话“……人的常识在家庭四壁的生活范围中,虽然是极可尊敬的伴侣,但是一踏上广大的 Recently, the preparation of many important industrial products is achieved under high pressure, therefore, the corresponding research work is also strengthened. In recent years, he has published commentary and monographs specifically explaining the application of high pressure, which indicates that people have drawn great attention in this respect. Some of the phenomena observed in high-pressure research work are often hard to imagine under ordinary conditions. For example, evaporation of compressed solutions, delamination of gas mixtures, and the like. This made us have to recall Engels once said: "... human common sense in the four walls of the family, although it is a very respectable companion, but embarked on a vast
