• 中文摘要： 國產基本電子元件品質差距較大。本文係介紹一項低成本而「熱穩定度」良好之電路設計技術。在拷貝或複製已有的印刷電路時，尤須應用文中介紹之溫度補償技術。 原理上，依據波德 (Bode, H. W.) 所提出的靈敏度 (Sensitivity) 定義式，可以導出一則「溫度補償」方程式。文中以一個實驗，證明此方程式的正確性。 實驗結果與理論契合。實用時，可以筆算方法作電路粗略補償。精密補償，則需應用電子計算機輔助計算。一般設計，應用粗略補償的機會甚多，而精密補償很少需要。前述兩種補償法，文中均有介紹。在各元件溫度係數都已知時，亦可以計算機輔助，估計電路的熱穩定度。這些資料和方法，可供電子成品、半成品製造業和基本元件製造業者參考使用。
• 英文摘要： The fundamental electronic componentsproduced in Taiwan have different quality.Under such condition, this paper introduce alow cost design technique to improve the thermalstability of electrical and electronic equipmentsproduced here. This method can be used duringinitial scratch design. Or it can be used, withdigital computer, to perform circuit stabilityanalysis. While copying well-developed printedcircuit boards, it is important to find out thetemperature compensation relationships in be-tween parts of the original boards. According to the definition of "Sensitivity"exposed by H.W. Bode, a "Temperature Compen-sation Equation" is derived. Which can be used totell the proper polarity of temperature coefficientof each circuit component. It can also be usedto obtain fine temperature compensation. Anexperiment is done to check the validity of thecompensation equation. And the result agreeswith the theory. For gross temperature compensation, com-portents with linear temperature-dependencecharacteristic are prefered. As for "Fine" com-pensation, the closed form solution of the tem-perature compensation equation must be ob-tained．There are very few occasions that needfine compensation. However, anti-compensationmust be avoided, i．e. gross compensation shouldbe done whenever it is possible. The tempera-ture dependence characteristics of many popularused R, L, C compnents are graphically shownfor quick reference and gross temperature com-pensation. This technology should be helpfulto the manufactures and designers of electronicequipments and components.
