“第二信使”的语义构建与科学修辞

The Semantic Construction of the “Second Messenger” and Rhetoric of Science

20世纪40年代,中间代谢和内分泌学作为两个不同的学科,拥有着各自不同的实验研究体系和学科语言系统。萨瑟兰作为中间代谢领域的一名研究者,使用内分泌学的学科语言首次提出了"第二信使"的概念。在"第二信使"知识构建的过程中,科学修辞起到了非常重要的作用。然而,这并不暗示修辞就是一切。只有对生化技术的娴熟运用,才使得萨瑟兰得到一个观察。而这个观察作为发现的硬核,通过科学修辞的手法在新的语境下被重新解释,从而最终形成一个新的知识构建。

As two different disciplines,in the 1940 s,the intermediary metabolism and endocrinology,had different systems of experiment and scientific language. Sutherland,a worker in the field of intermediary metabolism,first put forward the concept of＂second messenger＂by using the endocrinology language. In the process of the construction of the ＂second messenger＂,rhetoric of science plays a very important role. However,we do not imply that rhetoric is everything. Only through skilled use of biochemical technology,did Sutherland get an observation. And as the hardcore of the discovery,this observation is reinterpreted in the new context through using the rhetoric of science,thus forming a new construction of knowledge.
