THE FUNDAMENTAL CAUSE OF EVOLUTION OF THE EARTH''S SURFACE FEATURES     

李四光 《地质学报》1926,5(3)

In the days when the uniformitarians triumphantly fought against the catastrophists, it was apparently thought by the leaders of the rising school that the ebb and flow of the oceanic water had been going on indefinitely all over the surface of our planet for an untold length of time. Beyond this, little was then  相似文献

波浪的非线性显式弥散关系     

王亮  李瑞杰  Dong-Young LEE 《海洋湖沼通报》2002,1(3):9-18

波浪的非线性弥散关系在应用于求解波浪的变形问题时很不方便，需要与含非线性效应的缓坡方程一起进行迭代运算，往往导致数值计算的计算量太大，计算过于复杂。采用显式形式表达非线性弥散关系，可以克服上述缺点，大为简化波浪变形数值计算的计算量。本文通过将现有的非线性弥散关系进行分析比较，给出了一个更为一般的非线性弥散关系及其显式表达式，经比较可知，该显式弥散关系与相对应非线性弥散关系吻合的很好。本文最后用该显式结合含弱非线性效应的缓坡方程，对复式浅滩地形上的波浪折射绕射进行了计算。结果表明，考虑弱非线性可以得出与实验数据更为相符的结果，而采用显式弥散关系可以有效提高计算效率,在波浪的非线性计算中不失为一种切实有效的方法。  相似文献
