	3.	Prestack migration method , based on wave motion equation , is also developed for receiver function , and compared with ray method . both p - to - s conversion wave and direct p phase contained in receiver function are migrated and imaged by reverse - time migration for data gather including all receiver functions recorded in all seismological stations for one event , and imaging profile is finally obtained by stacking for all events 本文还在接收函数射线反投影叠加成像的基础上，提出了一种基于波动方程的接收函数叠前偏移成像方法，将同一事件接收函数中的转换波和直达p波震相以各自的速度向深度方向逆时延拓成像，并通过不同慢度接收函数的叠加，得到最终的偏移成像结果。
	4.	A new finite - difference method is developed for seismic modeling and reverse - time migration based upon the voronoi cell construction on irregular grids . curved velocity boundaries and irregular earth surface can be accurately represented using the irregular grid implementation . therefore the modeled and migrated results can be more accurate , and meanwhile , the efficiency is still preserved using an explicit finite - difference scheme 本文的方法可以实现任意非规则网格上的显式差分计算，因此该方法在保持了传统的矩形网格差分算法简单、高效特点的同时，又能精确地描述弯曲界面和起伏地表，提高了有限差分地震模拟和偏移结果的精度。
