摘　　要：为进一步优化无为原理在潮汐分析和预测中的应用,结合传统调和分析,将标准时频变换难以区分的分潮进一步分离。基于标准时频变换的无为原理,能从验潮数据中将各个分潮信号从其标准时频谱中直接提取,但是由于分辨率上的限制,分潮S2与K2、P1与K1混叠而难以区分,而在传统调和分析成功将混合分潮分离后进行预测,能使精度提高了20%~30%。In this contribution, we combine inaction principle and conventional harmonic analysis to distinguish the mix tide which couldn’t be separated using normal time-frequency transform only for a better analysis in tide analysis and prediction based on inaction principle.Although tidal constituents can be directly recognized and extracted from its NTFT spectrum based on Inaction principle, S2,K2 and P1,K1 couldn’t be separated due to the limition of resolution.Prediction accuracy can be improved by 20 percent to 30 percent if using conventional harmonic analysis distinguish mixture tides first.
