The full space calculation model, which suits for the asymmetric structure sometimes even including air below the surface of medium, can enable simulative result to approach real one. The FDTD algorithm based on the mixed ABCs is proper to calculate the transmission line where the electromagnetic wave is transmitted in order to send electromagnetic energy along central conductor. The calculation efficiency will be raised if the PML absorbing boundary condition is set on both planes of transmitting direction and so is the MUR two-order absorbing boundary condition in the other planes.

全空间计算模型是适合所有的不对称结构的待研究体的，而且包括了介质下面的空气部分，使仿真更加的接近实验真实情况；基于MUR-PML混合吸收边界条件的时域有限差分法非常适合计算传输线这种结构，因为传输线是传送电磁波的，电磁能量主要是沿着中心导带行进，因此在两个传输端面上设置PML完全匹配层吸收边界条件，在其他面上设置MUR二阶吸收边界条件，会大大提高计算效率，而且计算结果与XFDTD仿真软件计算结果相比较，基本趋于一致。

Its theory is: evaluate periodical by various methods, and then make the results standardization, select the extreme value of these results as the final score of periodical. The research indicates that it is must been used carefully to calculate weight by combined assessing method; assessing methods based on order can't been used to combine; combined assessing based on extreme value method is propitious to establish harmonious relationship between assessor and assessee.

其原理是，首先选用各种可行的评价方法进行评价，然后将评价结果标准化，将同一期刊不同评价结果的极大值作为该期刊的最终评价结果，取得了较好的效果，研究表明，采用组合评价进行权重计算必须慎重使用；基于秩序的评价方法不能用于组合；基于极值法的组合评价方法有利于建立和谐的评价者与被评价者关系，结果容易得到公认。

Secondly, two physical models were constructed, which could model rough surface and describe the features of the earth surface, such as chine, neck, valley and hill, etc. According to difference method, the ""true"" volume of the physical models were measured, which was 13260cm3 and regarded as the analysis foundation of the precision of the volume that was calculate by DEM. The discrete dada of the models on a regular spacing of 1cm were collected by 3SPACE FASTRAK and the DEM was obtained by interpolating the discrete dada through GIS software. Based on the volume of the models calculated by DEM, different interpolating methods (IDW, Spline, Natural Neighbor, and Kriging) and variation of grid spacing of data were compared and their effects on precision of volume calculation were analyzed.
