Combining historical methods with insights from linguistics and film studies, this study discusses the historical resonance of films such as Lawrence of Arabia (1962), Gangs of New York (2002) and United 93 (2006), and investigates the parameters and limitations of fiction film as a way to access history.

这项研究结合了历史方法和语言学家及电影研究领域的观点，探讨了一些电影引起的历史共鸣，如《阿拉伯的劳伦斯》（1962），《纽约黑帮》（2002），《联航93》（2006），分析了将科幻电影作为通向历史之门的变化因素和局限性。

Background Recently , most of the authors consider that muscle injection is the cause of the gluteal muscle contracture , and release and excise the fibrous contracture tract of gluteal muscle (gluteus maximus , gluteus midius , gluteus minimus) can improve the adduction and internal rotation of hip joint.

背景：目前大部分作者认为臀肌挛缩症是臀部肌肉注射引起并与患者遗传因素有关的一种疾病，治疗方法多采用臀部切口，对臀大肌、臀中肌、臀小肌中的挛缩组织进行松解，以改善患侧髋关节的内收与内旋。

In integration, explicit formulation has been used with the lumped mass matrix so that it facilitates the calculation of the displacement and ayoids the convergence problem caused by the nonlinearities in material, geom.

数学模型采用物质坐标系中的修正的拉格朗日描述，采取集中质量矩阵，用动力显式积分的方法，使位移计算显式化，避免了由材料、几何、边界条件等高度非线性因素引起的计算收敛问题。

The changes of soil structure caused by seasonal factor would affect the safety of grounding system.

季节因素引起的土壤结构的改变必然影响地网的安全性能。

The main factors determined IMS resolutions are the initial ion gate pulse width and diffusion in the drift tube. We conclude the homogeneity of the electric field in the drift tube through analyzing the relation between resolution and ion gate pulse width and drift tube temperature. It is still concluded that inhomogeneity of the electric field has much influence on IMS resolution, which is generally ignored previously.

IMS分辨率最主要的决定因素是离子门脉冲的开门时间和离子在迁移管内的扩散效应，根据在不同离子门开门时间和不同温度下所作的分辨率关系曲线，我们推断出了迁移管内电场的均匀情况，并且得出在一般的IMS工作条件下，迁移管内电场的不均匀对分辨率也有很大的影响，这在以前人们讨论IMS的分辨率时通常被忽略，并没有引起足够的重视。

Cervical factor infertility is suggested when welltimed PCTs are consistently abnormal in the presence of a normal semen analysis.

如果时间选择合适的性交后试验持续异常而精液分析正常时就要考虑宫颈因素引起的不孕。

The factors that may hamper the recycling, the split of atomic levels due to Zeeman effect and the increase of Doppler shift in a slow-wave field, are analyzed and the possible ways to solve them are suggested.

并就当前阻碍实验顺利进行的磁场中基态能级塞曼分裂和慢波引起的多普勒频移的增大等因素进行了分析，提出了解决问题的可能途径。

Through analysing the conditions, it can be known that there were different viewpoints on Gide in the two periods, and it's the result of being effected by double elements, the author's personality and the accepting environment.

通过分析这两个时期纪德在中国的接受情况可以看出，不同历史时期的不同情境下，纪德在中国所引起的关注点是不同的，这是作家的个性和客观接受环境双重因素影响下形成的结果。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。
