The inverse solution was obtained through minimizing the object function using CGM based on the directproblem.
反问题的解在正问题的基础上通过共轭梯度法最小化目标函数得到。

A more directproblem is that when people reflexively use data types, they often end up reducing flexibility in unanticipated ways.
更直接的问题是，当人们反射性地使用数据类型时，常常以无法预料的方式降低灵活性。

In this paper it is suggested to solve the directproblem of magnetic prospecting under complicated conditions by coupling finite element method and boundary element method.
