It is a necessary input for designing matrix stimulation treatments of multiple layers, if only to account for and potentially take measures to control crossflow between zones.
如果只是说明并且可能采取措施来控制地层间的交叉流动，那么它必须输入，以便设计基质增产措施。

The LS coupling representation of electron -ion system is used, the exchange effect is taken into account and the angular factors of collision matrix elements are treated in detail.
其中采用了电子与离子系统的LS耦合表象，考虑了交换效应，仔细处理了碰撞矩阵元的角部分因子。

Stiffness matrix and equivalent nodal force formula, which take into account of the influence of shear lag, are derived subsequently on the basis of the definition of stiffness coefficient.
