摘　　要：在多重平均谐波分析的基础上，提出了一种新的谐波分析算法，可以准确方便地计算出各次谐波的幅值和相位。通过计算机仿真和实验验证证实了该方法的准确程度，并采用蒙特卡罗实验研究了噪声的影响，得出了工程实用的结论。Based on the fundamental principle of muhiple-average harmonic analysis, a novel algorithm for harmonic measurement is proposed, with which the amplitude and phase of the harmonics can be calculated accurately and conveniently. Its accuracy has been verified by computer simulation and physical experiment described. Further, the influence of noise at samples to the result has been discussed by Monte Carlo method and a qualitative result for practical engineering application is given.
