针对称重仪表检测电路中输入与输出值之间存在非线性关系的特性，在比较了几种非线性校正方法的基础上，给出了一种易于微处理器实现的正交多项式的非线性校正方法，求取称重仪表检测电路的非线性特征，实现了称重仪表的非线性校正。同时讨论了该算法的原理、校正参数的空间复杂度和算法的时间复杂度，从而论证了此算法在简单微处理器上的可用性，并以3阶多项式为例介绍了该算法的实验效果。实践表明，该算法简单实用，效果较好。

For the characteristics that non-linear relationship exists the weighing instrument detection circuit between input and output, comparing the basis of several non-linear calibration methods, this paper gives an easy microprocessor nonlinear orthogonal polynomials correction method. It obtains nonlinear characteristics of the detection circuit to strike weighing instruments to achieve a non-linea r correction weighing instruments. Also it discusses the principle of the algorithm, the correction parameter space complexity and time complexity of the algorithm, which demonstrates the availability of this algorithm on a simple microprocessor, and takes third-order polynomial example to introduce the experimental results of the algorithm. Practice shows that the algorithm is simple and practical.
