The results are verified from deep to extremely shallow water conditions. The shoaling waves, standing waves, 3D disturbance waves, tidal waves and solitude waves are simulated and verified,and waves over an underwater bar,the diffraction near single breakwater, breakwater gap, offshore breakwater, Breakhoff experiment are taken into account in this model. Furthermore, the wave harbor resonance under special topography, and "Bragg" resonance are simulated. The wave refraction problem under current fields,the nonlinear wave refraction-diffraction under "Arthur" current field, and the wave propagation under slowly varying current field are studied. The favorable calibrations show the model's feasibility in dealing with the wave nonlinearity and simulation in both deep and shallow water.

These are analytical solutions based on the propagation of singularities in the medium.

本学位论文是在国家自然科学基金项目支持下完成的。

As solitaries from before have grown many differences that contain different backgrounds, such as academic fashions, civil economics, political condition, social environment, religious belief, and cultural definition of that dynasty, as well as different personality and temperament. Solitaries have lived up diversified values within regions such as moral cultivation, aesthetic value, knowledge propagation, and academic research in their time.

而历代隐士亦随著当代的学术思潮、民生经济、政治局势、社会风气、宗教信仰、文化内涵等不同的背景，加上个人性格与素养的差异，而在另一种生命型态中，诠释著不同的隐逸特色，发展出更深刻、丰富的隐逸内涵，并在道德修持、艺术审美、知识传布、学术研究等方面，彰显著多样化的价值。

The influence of water sprays on gas flame propagation is experimentally studied in the present paper.

With different propagation background, the audience has different attitude and comments on different media and information, either accepting it or partly accepting it, or spurning it, or criticizing it.

所以，在传播的互动过程中，我们必须中充分认识到受众是传播学中的一个重要概念，它是传播活动中的听众、观众和读者的总称。

For strong disturbance case in which Δp is set to be 5, by examining the distributions of relevant physical quantities along radial direction and the normal of wave front, we can infer that the slow wave introduced by the strong pressure pulse steepens into slow shock during the propagation process.

与二维情形类似，沿由源区出发的径向，可以分辨出压力脉冲增长相所引起的前导快波与后随慢波的传播，同时还可观察到压力脉冲恢复相所导致的快模磁声波的传播，由于传播速度的差异，该波动在向外传播的过程中逐渐超过后随慢波。

Based on the fact that the different modes of Rayleigh wave have different propagation velocities, the signals of Rayleigh wave which superposes in time domain can be separated in frequency-wave-number domain, different modes of Rayleigh wave are separated and extracted by Fourier transform.

摘 要：应用Fourier变换法分离提取地震记录中不同模态的瑞雷面波，其原理是：利用瑞雷面波各模式传播速度的差异，将时间域中叠加在一起的瑞雷面波信号在频率波数域中分开，以此实现分离提取各阶模态瑞雷面波。

In the present study, tiller formation and growth characteristic for three kinds of Hemarthria compressa genet at different growth and development stage were analyzed. It was found that Hemarthria compressa tillered very regularly at the seedling stage, with tillers coming out in batches after 5~7d, 23~26d, 41~45d of propagation. When the plant was 15~20cm high, it started to grow horizontally and the regenerative tiller started to grow vertically.
