摘要
一、問題 在現代生产技术中,人和机器可以看作是一个統一的系統。这一系統的中心环节是人。人凭借自己的感官从仪表和信号得到有关机器的运轉状态和生产过程的变化的信息,經过一系列的思惟活动,然后作出判断,并通过操作活动对机器和生产过程进行控制和調节。关于人和机器的这一方面的关系,以及关于机器、仪表、信号和操纵装置的設計如何适应人的感知、思惟和运动的特点,以便使“人机系統”达到最高效率的研究,已經形成一个新的学科分支,即“工程心理学”。本研究所涉及的閃光信号的頻率选择問題,就是属于工程心理学的范围。
The purpose of this study was to determine the optimum frequencies and light-dark ratio for two flash light signals which are supposed to he incorporated with a steady light signal. Experiments were performed both under low illumination and under sunshine. An equal discriminability scale for flash light frequencies has also been constructed. The results indicated that the optimum frequencies for the signal with high flash rate fall around 160 cycle per minute with light-dark ratio 2:1, and that for the signal with low flash rate fall within the range of 55—60 cycle per minute with light-dark ratio 1:1.
