英文摘要	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. trend and plunge of the symmetry axis, and depth distribution of anisotropy, on the variation pattern. We applied the method of receiver function with anisotropy to one station-JJJX, which is located in the Taihangshan Mountain Range (TMR) of North China. Our results show that the upper crust (0 similar to 2. 4 km) has about 10% anisotropy with a slow symmetry axis, which might be caused by aligned microcracks. The trend direction of the symmetry axis has a good correlation with the faults distributed in this area. With a fast symmetry axis, the middle crust (2.4 similar to 22 km) has about 8% anisotropy associated with aligned crystals, which might be a result of the uplifting of the TMR occurred in Cenozoic.
