摘　　要：论述了计算机求解补偿压力传感器的热零点漂移、热零点温度系数和满量程热漂移误差的串并联电阻问题．列出压力传感器电桥电路的基尔霍夫方程（组），再把电桥电路测试数据用最小二乘法拟合成直线，进而形成计算补偿电阻的条件，在满足补偿条件和使用要求的基础上，迭代方程（组），求得串并联各电阻的值．The paper discuss how to calculate series-parallel connection resistance which compensates the offset thermal drift, offset thermal drift coefficient and full measurement of pressure sensors. Jerhuofu equation comes from pressure sensors bridge circuit. The testing data from the bridge circuit is made to be a line by least square method. Then the slope of line is a condition to calculate resistance. Meeting the demands of compensation and applying, the series-parallel connection resistance through equations.
