It is postulated that a high conductivebody exists in the lower crust or upper mantle.
据此推测在地壳下部或地幔上部存在一高导体。

On assumption that the surface of the conductivebody is uniformly charged, the method for evaluation of the electric field and potential distribution is insignificant in practice.
假设带电体表面均匀带电，运用积分求电势、电场分布的方法，实际意义不大。

As to the rapid piece of prototype, we adopted new technology to let it become an electric conductivebody firstly and then fabricate the mould with the method of pulse electroforming.
