【摘要】 在讨论了压力传感器非线性输出误差分布规律的基础上，提出了非线性拟合方法，介绍了误差修正即拟合因子中三个基本参量（Ａ，ω，φ）的取值方法。通过对两个压力传感器实际输出数据的修正，使其线性度分别由拟合前的ｌ．８９％、２０６％降低为拟合后的０．６９％、０．３３％。更多还原

【Abstract】 On the basis of discussion of error distribution of non-linearity of pressure sensors, a new fitting method is presented. It introduces the taking-value method for three basic parameters (A, ω, φ)in error modification, i.e. fitting factors. Through the fitting of realistic output data of two pressure sensors, the non-linearity degrees are reduced from １ .89% and 2.06% before fitting to 0.69% and 0.33% after fitting respectively.更多还原
