The calculation of dipole moment by MEEM The dipole moment is a physical quantity, which can indicate the charge distribution of the molecule.

中文摘要：偶极矩是表示分子中电荷分布情况的物理量，可以由分子的对称性推测分子有无偶极矩，也可由分子有无偶极矩及偶极矩的大小了解分子结构的信息。

In this thesis, two main parts are included, the first focuses on the characteristics of high-resolution spectra of free radicals in magnetic field, the second concentrates on the measurement of electric dipole moment of free radicals by Zeeman and Stark effects simultaneously.

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。

We have done some exploratory work from several aspects to generalize the Brownian motor to the more real situation: The model which molecular motor has internal degree of freedom; The track on which the Brownian particle moves cannot be completely ordered and contain certain amount of disorder, the model is rocking ratchets with stochastic potentials; A two-dimensional ratchet model with a non-conservative force to realize the coupling between the mechanical and chemical processes.

目前大多数的研究工作是把分子马达抽象为一维的点粒子，我们在推广布朗马达到更真实的方向上开展了以下几个侧面的研究分子马达动力学行为的探索性工作：分子马达具有内部结构的电偶极子模型；考虑分子马达的轨道不规则、不光滑的摇摆棘轮模型；提出一个具有非保守脉冲力场的二维棘轮模型。

Through the Raman experiment data obtained above, the order parameters were determined and the orientation distribution graphs of BY and MO in BSFs were given. BY molecules were mainly oriented towards the plane of BSFs, but there was some probability towards other directions. The phase transition of the BSF from gel-to-liquid crystal resulted in a decrease of orientation distribution along the plane of the BSF and a increase diverging from the plane.

BY分子主要沿90°方向取向，但其它方向亦有一定的取向几率；MO分子的取向分布对BSF相变的反映是其有序程度的变化，BSF从凝胶态到液晶态的相变导致MO分子沿90°方向取向几率减小，而沿其它方向的取向几率增加，这实际对应MO分子热运动程度的增加。

But at low pressure, the continuum theory is no longer suitable and only the molecular dynamics method is passably valid. However, there have been yet a few studies on the squeeze film of micro-resonators in the free-molecule regime, and no 3D model of MD has been presented for SFD.

当气压很低时，气体连续介质模型不再适用，只能采用分子动力学方法但是，当前关于自由分子区域中的微谐振器件挤压膜阻尼的分子动力学研究非常少，为了避免计算量过大，还未有三维的挤压膜阻尼分子动力学模型。
