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.
