-d wave spectrum

In this paper, the probability distribution and spectrum characteristic of obliquity and multi-directionality wave forces are studied systemically by a 3-D hydraulic model test.

本文在物理模型试验的基础上，系统研究了斜向和多向不规则波波浪力的概率分布和频域特性。

There are a lot of mode wave patterns near P-wave velocity line in 2-D spectrum, which have dense special distribution and large amplitude when the radial thickness of model well is thicker ;

当模型井的径向厚度较大时，二维谱中纵波速度线附近的模式波类型较多，空间分布较密集，幅度也较大；

With the method of plane wave spectrum(PWS) , a 2-D electromagnetic scattering problem, the influence of a cylinder on a continuous antenna, is solved. The formulae given in this paper are accurate.
