摘要
本文提出悬沙输运时均通量可在频域上用共谱密度函数表达。据此分析了长周期和12h,6h等潮周期波动分量对河口、潮汐通道及浅滩区悬沙净输运的重要贡献。文章还讨论了它们的形成机制和从频域上分解扩散系数的可能。
It was deducted that S (concentration of suspended sediment) -V (water current velocity) cospectrum expresses the contributions to net flux from domain of frequency. Main contributions from long-term fluctuation and some tidal fluctuations (T = 12h or T = 6h) were gained by comparisioh among cospectrums of some stations in tidal inlets and estuaries. Discussed also was the causes and the desoluted form of dispersion (diffusion) coefficient.
