折射

It compensated masterly both linear birefringence and Verdet constant, which affected the stability of OCT mainly, by combing optical measurement and comparing measurement.

它将光学测量法与比较测量法相结合，巧妙地实现了对线性双折射和Verdet常数这两个稳定性影响因子的同时补偿。

As the spectral width (Full width half maximum: FWHM) range from 6nm to 60nm, the simulation results show that the effect of the variation of the FWHM upon the output is small. When only the Verdet constant is considered, the output increased slowly with the increase of the FWHM. The simulation results are verified by the experiment.

当光源光谱宽度在6nm到60nm之间变化时，不同谱线宽度光源对系统输出影响的仿真结果表明：光源谱宽变化对系统输出的影响相对于其单色模型来说，相对变化小于10~(-3)，因此光源谱宽变化对系统输出的影响较小；如果完全消除了线性双折射和反射相移，则系统输出随光源谱宽的增加有微弱的增加：由于Verdet常量的影响最大，所以系统输出随光源谱宽的增加有微弱的增加；实验结果验证了该结论。

However, various methods are used to suppress surface waves from shooting to receiving in the process of seismic survey, thus research should be carried out in the following aspects:① joint inversion with surface wave, refraction first break and microlog data;② offset range and the relation between group interval and surface resolution suitable for use in surface wave analysis;③ the influences of lateral relief of array on propagation of surface waves;④ method for Hi-Fi purification of surface wave signals;⑤ method for extracting dispersive curve through time-frequency analysis;⑥ forward modeling and in-version methods of surface wave in view of three-layer structure.

The three novels catch hold of the kernel of contradictory political forces, and reveal the conflicting relationship between the factors of the desires for power in English cultural tradition, and refract the paradoxes formed from the unsolvable problems in the political modernization: the modernization in England upgraded prolificacy with an unprecedented speed, offering opportunities of emancipation of personal desires, the appealing to personal power in politics pressed for a breakthrough in the traditional political setups, leading reform to modernization, which emancipated political forces, aggrandized political rights, and satisfied some people\'s desire for power in a certain extent.

这三部小说抓住了现代化进程中各种政治力量的相互矛盾这个核心，揭示了英国传统文化中欲望力量诸因素相互冲突的关系，折射了政治现代化难以解决的矛盾所形成的悖论：一方面，英国现代化进程前所未有地提升了生产力，使人的个性解放成为可能，个人权利的诉求迫切要求冲破传统的政治格局，使政治通过改革走向现代化。
