一、引言长时期地处于封建社会及半殖民地社会的中国,科学与工程都不能发达,劳动人民关于这方面的智慧,也得不到发挥与鼓励。肯定的说,过去我们劳动人民关于化学工程方面的经验和成就,是相当好的,但由于过去轻视劳动、轻视“雕虫小技”的思想,没有被写历史的人所重视,以致极少记载,或竟致失传,实深可惜。近三十年来(1922—1952)中国化学工作者在化学工程虽然有些贡献,但一般的说是很有限的, I. INTRODUCTION China, which has been in a feudal society and a semi-colonial society for a long period of time, can not develop its science and engineering. The working people’s wisdom in this regard can not be played and encouraged. To be sure, the experience and achievements of our working people in chemical engineering in the past are rather good. However, due to neglect of labor in the past, the slightest neglect of the idea of ​​“carving up evil spirits” has not been taken seriously by those who write history, so that it is rarely recorded or Actually lost pass, real pity. In the past three decades (1922-1952), although Chinese chemical workers made some contributions in chemical engineering, they are generally limited in number.
