Therefore, a methodofinversion for calculating certain parameters of the vertical earthquake force is here suggested.
所以，按反算办法，对计算竖向地震力的某些参数提出初步建议。

However inversion will bring the problems of multiple solutions. Therefore, we established CBM fracturing parameter database. In this way, we solved the multirole-solution ofmethodofinversion.
为此，研制了煤层压裂参数数据库，用以确定分析参数的上下界，从而较好地解决了反演算法的多解性问题。

In these examples, one can not only solve the inversion problems by the methodof explicit function, but also make the calculation simple and the result accurate.
