According to these accomplishments, several techniques are expounded emphatically in this paper, including 3d refraction statics, coherent noise suppression by prestack wave field separating ( prestack fx noise attenuation ), 3d prestack multiple domain random noise attenuation, multiples attenuation, nmo of unsymmetrical hyperbola, dynamic replacement of wave equation, surface - inconsistent residual static, super bin stacking, poststack depth migration and prestack depth migration. all the techniques have been applied in seismic processing of 2d, 3d and wide - line profiling and obtained good results

During this evolution, seven second - order tectonic units were formed ; from north to south are the mingqianri cretaceous residual sea basin, the arsuo tectonic melange zone, the taricuo - wenbu yenshan magmatic arc belt, the cuoqin - bangduo late paleozoic composite back - arc basin, the jiangrang - geerdi faulted uplift, the gangdise - chazi himalayan magmatic arc belt, and the xigaze - anba fore - arc basin. these units comprise important parts of a poly - arc - basin system and exhibit evolutional features of mesozoic to cenozoic arc - basin systems. mosaic pattern of these tectonic units delineates the lithosphere coupling processes of the gangdise tectonic belt under mechanisms such as back - arc basin attenuation and arc - continent collision
自中新生代以來，岡底斯構造帶經歷了洋殼俯沖、弧陸碰撞、陸內俯沖-碰撞、走滑和塊段隆升的多階段構造演化歷程，形成了由北向南七個二級構造單元，即岷千日白堊紀殘余海盆、阿索構造混雜巖帶、它日錯?文部燕山期巖漿弧帶、措勤?幫多晚古生代復合弧后盆地、江讓?格爾耿斷隆、岡底斯?查孜喜馬拉雅期巖漿弧帶、日喀則?安巴弧前盆地。
