摘　　要：提出一种用最小二乘支持向量机构成补偿模型的热偶规真空传感器非线性补偿方法,用现场采集的测量数据组成实验样本,实验结果表明所提出的方法可有效降低热偶规的测量误差,补偿精度优于普通支持向量机。An approach to compensate the nonlinear characteristics of thermocouple vacuum gauge is developed,least squares support vector machine（LSSVM） is adopt as compensation model in this paper.The results of experiment based on the samples obtained on site show that the measurement errors are decreased significantly,and compared to the SVM model,the proposed approach exhibits higher accuracy.
