一、前言近来,由于热敏电阻具有尺寸小,热惰性低,改善了的灵敏度和可靠性及总体上改进了的特性,因而它们在快速和精确地测量温度时得到广泛的应用。然而,由于热敏电阻其阻值随温度的变化是高度非线性的,从而在感兴趣的温度范围内不能导致线性的输入/输出关系,因此热敏电阻难于单独使用。为克服这一缺陷,可以使用一个与热敏 I. INTRODUCTION Recently, thermistors have found wide application in fast and accurate temperature measurement because of their small size, low thermal inertia, improved sensitivity and reliability, and generally improved characteristics. However, the thermistor is difficult to use alone because its resistance is highly non-linear with temperature and therefore does not result in a linear input / output relationship over the temperature range of interest. To overcome this flaw, you can use one with thermal
