在二进制的冲突模型里，在试验和目标粒子之间的库仑相互作用被筛选，因为目标的极化作用。

In the binary collision model, the Coulomb interaction between the test and the target particles is screened because of the polarization of the target.

在本文中我们得到了极化和关联所贡献的单粒子位虚部的解析表达式，并通过色散关系计算了它们对单粒子位实部的贡献。

The imaginary parts of the polarization and correlation contributions are calculated analytically and the real parts of them are obtained by means of dispersion relation.

而细胞膜内钠的阳粒子则又使细胞膜表面的退极化现象进一步加重，从而使更多的钠阳离子得以进入细胞膜。

Within the cell membrane and sodium-particle and then retreat to the cell membrane surface to further increase the polarization, so that more sodium cation to enter the cell membrane.
