论文部分内容阅读
读了许仕国同志在本刊1984年第4期发表的文章后,再翻阅叶芄生同志的《黑白元件热特性的研究》一文(见本刊1983年第11期),很有收益。我想就黑白元件的工作电源提出以下两个问题进行讨论。1、关于黑白元件的工作电流问题许仕国同志在文中说:“众所周知,任何热敏电气元件在周围环境温度变化的情况下工作是不能保证其电流不变的,恰恰相反,在实际应用热敏元件时,就是要利用它随周围环境温度变化而其通过的电流也发生
After reading the article published by Xu Shiguo in the 4th issue of this issue in 1984, he read the article entitled “Research on the Thermal Characteristics of Black-and-White Components” by Comrade Ye Tiesheng (see Journal No. 11, 1983), which is very profitable. I would like to discuss the following two questions about the working power of black and white components. 1, on the black and white components of the working current problems Comrade Xu Shiguo said in the text: "As we all know, any thermal electrical components in the ambient temperature changes in the work is not guaranteed its current unchanged, on the contrary, the practical application of thermal components When it is to take advantage of it with the ambient temperature changes through the current it also occurs
