一、前言近三十年,在工程方面利用热敏电阻测温日益增多。它与金属热电阻相比其灵敏度高、体积小、反应快、功耗小,故在快速温度测量、点温测量及表面温度测量中有着广阔的应用前景。而由于热敏电阻R_T-T特性的严重非线性,使其应用受到一定的限制,因此线性化是热敏电阻测温的重要课题。目前国外对此研究甚多,国内有些单位也进行了这方面的工作。我们从1981年起对热敏电阻线性化问题的研究进行了
First, the preface Nearly three decades, the use of thermistor temperature measurement in engineering is increasing. Compared with the metal thermal resistance, its high sensitivity, small size, fast response, low power consumption, it has broad application prospects in rapid temperature measurement, spot temperature measurement and surface temperature measurement. However, due to the serious non-linearity of the thermistor R_T-T, its application is subject to certain restrictions, so linearization is an important issue for thermistor temperature measurement. At present, there are many studies abroad on this topic, and some units in China also carried out this work. We have been studying the problem of thermistor linearization since 1981
