查询词典 seismic

The pseudo delta function in seismic method is used to simulate the electric dipole source in finite element simulation, In this paper, the author extend it into three-dimensional case from which singularity from source is eliminated, and also the the stability of the equation is remarkably.

把应用于地震模拟中的伪delta函数引入到可控源电磁法中的有限元模拟中，并把其扩展到三维情况下，用源周围的小块区域代替偶极子源，从而消除了源点的奇异性，提高了方程组的稳定性。

In the western region of Sanhe-Pinggu earthquake area, the stacked deep seismic reflection section shows 2～3 groups of strong reflective layers and a series of basement faults. In the eastern region of Sanhe-Pinggu earthquake area, there is a set of dense, westward-dipping, reflective strata with relatively strong energy, which have the typical characteristics of sedimentary basin. The largest depth of the sedimentary basin is about 8～9 km.
