【摘要】 本文利用广义线性反演技术,对马鞍山-启东之间的三个地震剖面的各种不同的折射波和反射波的到时进行了联合反演,较快地计算出该地区由五层介质组成的地壳结构,马鞍山以东的地壳厚度约32 km,而常熟以东约28 km,在中地壳内存在一个低速层.更多还原

【Abstract】 In the light of generalized linear inversion techniques,this paper carries out a synthetic inversion of the arrival times of refracted and reflected waves recorded on 3 seismic profiles which were situated between the Ma’anshan and Qidong areas.With less time required for the calculations, it is possible to obtain the result that the crust of that area is composed of 5 layers of media. The crustal thickness east of Ma’anshan is about 32 km,whereas that to the east of Changshu,about 28 km.It is also concluded that a low velocity layer exists within the crust of that area.更多还原
