摘　　要：针对数字型传感器-石英晶体温度传感器的非线性校正设计了几种方法,通过实验分析了这几种方法的优缺点和可行性。结果证明,综合传感器的特性、精度要求、软件实现的复杂程度等几方面因素,同时采用两种或两种以上方法,能够达到理想校正效果。The author designed several test methods according to non - linear correction in digital sensor, analyzed advantage and disadvantages of them. The results showed that ideal non- linear correction could be attained by using two and more methods at the same time, basing on many factors of sensor, characteristic, precision requirement and difficulty of software realization.
