导孔

To develop a backplane model, individual models for connectors, packages, PCB traces and vias are needed.

开发一种背板模型需要独立的连接器模型，封装，线路板上的线路以及导通孔。

By the use of the component sandstone electric conductivity model, the effect of the pore structure characteristic parameter to cementation exponent m and saturation exponent n in the Archie formula were studied. It can be found the cementation exponent m mainly reflects the pore space size and its sizes distribution. The m is bigger, the pore space is bigger, the throat is simpler, and the reservoir is better.

通过致密砂岩电导模型分析研究致密砂岩孔隙结构特征参数对Archie公式中的胶结指数m和饱和度指数n的影响，发现岩石胶结指数m主要是岩石孔隙空间大小及其大小分布的表征，m值越大的岩石其孔隙储集空间越大，孔喉越简单，储集性能越好；反之，m值越小，岩石储集性能越差。
