近年来，随着仪表和控制技术的进展，出现了一些新的自控名词，同时某些原定义的名词术语也赋予了延伸的内涵；但由于自控领域科技发展很快，对这些名词目前又难于有一个国际统一的标准可以查考，因此在应用中出现了一些困难和不同的理解。该文谨对在使用化工设计标准《自控设计常用名词术语》（CD50A4－84）中提出的某些商榷意见进行讨论，以便求得一致的认识。 In recent years, with the progress of instrumentation and control technology, some new self-control terminology has emerged, and some of the original definitions of terminology have also given an extension of the connotation; but because of the rapid development of science and technology in the field of automatic control, these terms are currently difficult There is an internationally agreed standard that can be examined, so there are some difficulties and different understandings in the application. This article discusses some of the debates that have been made using the Chemical Design Standard, “Self-Controlled Design Terminology” (CD50A4-84) in order to arrive at a common understanding.
