随着数字技术的发展，测量仪表的数字显示势在必行，而显示精度的高低完全取决于所获信号的线性程度，然而由传感器输送给测量仪表的电信号Ｖｉ往往都是非线性的，即Ｖｉ＝ＫＴｎ（１）式中，Ｋ是比例系数，在我们的工作中是通过实验来确定的，Ｔ是被测物体温度，ｎ＝２～... With the development of digital technology, digital display of measuring instruments is imperative, and the accuracy of display depends entirely on the linearity of the obtained signals. However, the electrical signals Vi transmitted by the sensors to the measuring instruments are often nonlinear, that is, Vi = KTn (1) Where, K is a proportional coefficient, in our work is determined by experiments, T is the measured object temperature, n = 2 ~ ...
