The results indicate that, in general, the critical temperature of the system becomes lower, compared with the 3D fluids, and is sensitive to the strength of the dipole moment, whereas the critical density shows an insignificant shift.

此外还考察了降低色散作用对系统汽液平衡性质的影响，发现降低色散作用会导致临界点下降，同时分子的偶极矩更加倾向处于分子所在的平面。

Meanwhile, the isomer with a larger change of dipole moment has larger value of the first hyperpolarizability during the charge-transfer process.

5， 6， 7顶点双取代碳硼烷桥连分子受推拉电子基的影响，5， 6， 7顶点碳硼烷的构型发生一定变化，碳硼烷中两个C原子间的距离变长；同时碳硼烷中两个C原子取代位置的不同，影响了分子的稳定性和极化率，取代基团与碳硼烷中成键数较低的C原子相连的异构体，稳定性较好且具有大的极化率； 5，6，7顶点双取代碳硼烷桥连分子形成一维结构有利于分子内电荷转移，在电荷转移过程中偶极矩变化较大的体系，其二阶NLO系数也较大。

Following the analysis, a new calculation model is developed, which takes the effect of the induced dipole moment of one atom on the polarizability into consideration, and the mathematical expressions are deduced in the cases of macro electric field parallel and perpendicular to the molecular axis, and at a random angle with the axis.
