Firstly , fkdv equation for the nonlinear surface wave was obtained by perturbation technique from potential flow theory 首先,从势流理论出发,利用摄动法,导出了非线性表面波遵循的fkdv方程。
< uk > is the plane - wave propagation factor in the uppermost medium and w is the propagation factor of the surface wave . < / uk > < uk >是最上部介质中的平面波传播常数,而w是表面波传因子。 < / uk >
Moreover , we analyze the frequency dispersion of rayleigh wave firstly , then we introduce the two methods of surface wave exploration 本文首先分析了瑞雷波的频散特性,并介绍了瑞雷面波勘探的两种方法。
Thickness measurement of coatings and characterization of surfaces with surface waves - guide to the thickness measurement of coatings by photothermic method 覆层厚度测量和表面波纹表征.光热法测量覆层厚度

Thickness measurement of coatings and characterization of surfaces with surface waves - part 2 : guide to the thickness measurement of coatings by photothermic method 覆层厚度测量和表面波纹表征.第2部分:光热法测量覆层厚度
Rayleigh surface wave exploration technique is used to get transverse wave speed of impermeable wall , which build on the theory of half space 在此基础上,我们把瞬态面波技术应用于防渗墙无损检测中以获得防渗墙的剪切波速。
We shall also consider the two types of surface waves , rayleigh waves and love waves , most widely observed in seismic prospecting and earthquake seismology 我们也要研究在地震勘探和天然地震中最经常观测到的两类面波- -瑞利波和乐甫波。
We research the appropriate way in non - destructive detecting by high - density seismic image and raleigh surface wave exploration technique 针对防渗墙的特点,本文对高密度震动映像和瞬态面波技术的在信号采集中的参数选择进行了深入的分析。
It shows that after being improved the vof method can be selected to further study the interaction between surface waves and sandbars on the seabed 表明vof方法经过进一步的改进与完善,可成为深入研究波浪与不同海底沙坝地形之间相互作用的有效方法。
