针对径流时间序列固有的强非线性和非平稳性特征,提出了一种将集合经验模式分解(EEMD)、样本熵(se)和正则化极限学习机(RELM)相结合的非平稳日径流预测方法(ES-RELM)。为充分提取径流序列的局部信息以提高预测精度,利用EEMD-se将径流序列分解为一系列差异度明显的子序列,然后根据各子序列的迥异特征构建了不同的RELM模型对各子序列进行预测,最后将各个子序列的预测结果叠加从而得到最终预测结果。将该模型应用于金沙江下游控制站屏山站的日径流预报中,与九种模型对比结果表明,该方法能有效提高日径流预报精度,是一种高效稳定的径流预报模型,为实现高精度实时径流预报提供了可能。

瑟是中国最古老的弹弦乐器,在春秋时期已经发展到了很高的水平,其时琴和筝都还是比较原始的形制。琴、筝在汉代都吸收了瑟制的优点而完成了对自身的超越,得以成功转型,并由此在艺术上获得了极大的发展。其中筝在当代又增加了弦制并吸收了瑟双手弹弦的方法而实与瑟合流。古瑟实是琴、筝发展的权舆。
