前言本文原为第一次研制双光束自动记录红外分光光度计后所写的设计原理方面的总结,现应国内进一步开展工作的需要,略加整理发表。文中着重阐明仪器的总体性能参数与各组成部分性能参数的关系。至于各部分如光路、电路和机械等的具体结构设计,不属于本文讨论的范围。由于本文目的是解决工程计算问题,故像公式(8)和(13)的数学推导从略,又如伺服系统时间常数的取值是按噪声滤波性能相当为准则,数学证明也从略。
This article was originally developed for the first time to develop a dual-beam automatic recording of infrared spectrophotometer after the design principles written by the summary, should be the need for further work in the country, slightly finishing published. The paper focuses on the relationship between the overall performance parameters of the instrument and the performance parameters of each component. As for the various parts such as optical circuits, circuits and machinery, the specific structural design, does not fall within the scope of this article. Since the purpose of this paper is to solve engineering calculation problems, the mathematical derivation of equations (8) and (13) is omitted. The value of the time constant of the servo system is based on the noise filtering performance.
