超声分散研究表明，使用聚乙二醇作为分散介质，可得到分散五天左右的悬浮液，但分散后粒度较大，使用十二烷基硫酸钠和顺丁烯二酸酐混合作为分散介质在水中分散效果较好，可稳定两天左右。

We investigated the receiver functions in a horizontally-layered medium with arbitrary oriented hexagonally symmetric anisotropy, and discussed the phenomenon of shear-wave splitting and energy deviation in an anisotropic medium. The anisotropic structure yields patterns of receiver function amplitudes and arrival times on both the radial and transverse components that are a systematic function of source-receiver back azimuth. We also investigated the influence of varying anisotropy parameters, e.g.

There was the jellylike medium in which the transverse wave spread. A deformation of the jelly, caused by the rotation of the sphere, moved through the medium.

又有一种胶状的介质，横波就是在这种介质中传播的，由于圆球的转动而引起球面上的胶状物的形变，这种形变在介质中向外传播。

Based on Born approximationmethod and the local principles of wave function in inhomogeneous medium and theray theory and the integral equation theory,this dissertation researches the theory andsimulation of the inversion method of large perturbational medium parameters andbreaks through the approximation condition of the small perturbational parametersand the weak scattering in traditional inversion method.

本文在Born近似方法的基础之上，基于非均匀介质中波函数局部理论和射线理论及积分方程等理论方法，对大扰动参数反演方法的理论和数值模拟进行了研究，突破了传统反演方法要求的参数小扰动和弱散射条件。

This thesis is to study the wave pattern selection in the heterogeneous reaction-diffusion systems, including propagation direction of target waves induced by a localized inhomogeneity, large heterogeneity maintained sinklike spiral waves in oscillatory media, and the competition of coherent wave patterns sustained by a localized inhomogeneity with turbulent waves in an excitable medium.

本论文主要研究非均匀反应扩散系统中波斑图的选择，如振荡系统中缺陷对其所诱导靶波传播方向的选择、缺陷所维持的一种新螺旋波－汇螺旋波的形成以及可激发系统中，缺陷诱导的有序波斑图和时空无序态的竞争和选择。

In the electric wave medium, under the term that audio-visual is combinative, the document is abundant, whole the role for of stereoscopically feeling strongly, its role also pile up one after another; but in the printing medium, under purely the sense of vision of the term, the form than the one of the document, straight-sight is weak, but it doesn't affect it in advertisement and the position in the activity with the role-play.

平面广告由版面大小、位置、色彩、文案和创意内容等要素构成，每一个要素都承担着一定责任，都拥有不同的地位，不同的组合、形式，不同的广告作品与广告活动都会产生不同的结论，有时也需要考虑环境的因素。

The former' wave width is medium. It feeds mainly on aquatic small insects of order Diptera and Trichoptera, foraging in 5-20cm above water surface and midium- complicated forest by trawling and aerial feeding. The latter's wave width is shortest, which have disadvantage to discriminate targets from enviroment. It feeds mainly on even smaller insects of order Lepidoptera and Diptera, foraging in wide space or sparse-foliage forest by aerial feeding.

为小型蝙蝠，前者声波带宽中等，主要以水生小型的双翅目、毛翅目为食，在水面5—20cm和中等复杂的林中进行拖网和空中捕食，后者声波带宽最窄，主要以小型的鳞翅目、双翅目昆虫为食，在开阔空间内或稀疏林中进行空中捕食，视觉可能在捕食中具有重要的辅助作用。
