With effect of geopotential and radiation energy, when the interior of the earth continued to melt, the surface of the earth solidified to form the original lithosphere.
当地球内部在重力势能和放射能的作用下继续熔融时，地球表面固化为原始岩石圈。

By using the spline interpolation, objective analyses of geopotential, temperature and surface pressure fields are tested and good results obtained.
