摘　　要：利用高次函数拟合处理热偶规传感器的非线性特性.所得函数直接写入热偶真空计单片机,用其处理热偶规采样数据.实验结果表明,其方法稳定性、精确性、速度均达到良好效果.This paper introduces a method of using high-order function fitting directly to deal with the thermocouple gauge sensor nonlinear.The gotten function is directly written into thermocouple vacuum gauge SCM,which is used to deal with sample data of thermocouple gauge.Experimental results show that the stability,accuracy and speed of this method are good,and the method is feasible.
