Potentiodynamic polarization and electrochemical impedance spectroscopy techniques were applied to investigate the corrosion behavior of LY12CZ in 3% NaCl aqueous solution. The effects of stress to anodic polarization behavior, free corrosion potential, breakdown potential, polarization resistance and double-layer capacitance of LY12CZ were summarized.

Since the eigenvalues of JM may be real, or pure imaginary, or some are real and others are imaginary, the presived tori may be hyperbol

我们考虑如下的依赖于参数的Hamilton系统：在以上假设下，我们证明了系统(3)的双曲不变环面大多数在摄动之下可以保持下来，并且频率可以是预先给定且可以保持不变的。

The self-centering mechanism design of bipolar endoprosthesis has advocated the use of offset centers of rotation between the inner and outer joint bearing surfaces to generate a self-centering moment on loading to prevent impingement of polyethylene rim and stem neck or cup fixed at wrong place. The design was used popularly, but the function of self-centering mechanism was discussed in very few papers. Three bipolar endoprosthesis were evaluated: UNIQHIP system, UHR system, and AML system.

双极式半人工髋关节的离心复位机构，是利用髋臼外帽的球心与股小球的球心两者在不同点，来防止发生髋臼外帽固定於髋臼中某角度卡住不动，而使股骨柄颈部固定磨损超高分子聚乙烯内衬之一边缘，进而加速超高分子聚乙烯内衬之磨耗，造成骨溶蚀与人工髋关节的松脱。

The motor molecule forms bipolar thick filaments that interdigitate with thinner actin filaments in the saromere, forming the basic contractile unit of muscle.

在所有的分子马达中，关于肌球蛋白的研究最多。肌球蛋白是肌肉收缩的关键成份，由它们形成的双极粗丝在肌节内同肌动蛋白细丝交叉对插，构成一个收缩单元。

This one-way wave equation fits eikonal equation and transport equation corresponding to full acoustic wave equation in travel-time and first order amplitude. According to the perturbation theory often used in inverse solution, we split the velocity field into intraformational constant velocity background and variable velocity disturbance. Then we calculate time-shift quantity of migration and amplitude correction coefficients for wavefield depth continuation in total uniform formation and each formation.

基于反问题求解中常用的摄动理论，把速度场分裂为层内常速背景和变速扰动，求得整个均匀层波场深度延拓的偏移时移量及振幅校正系数、各层的偏移时移量及振幅校正系数，从而得到一个基于傅里叶有限差分法的双域保幅叠前深度偏移算子方程。

Independent translational and rotational kinematic models of a Delta and 3-RRR mechanism based double parallel haptic device were established and the corresponding Jacobean matrix es were derived respectively.

建立了基于Delta和3-RRR复合结构的双并联式主手平动与转动独立的运动学模型，并推导出各自的雅可比矩阵，给出了局部灵巧度和全局灵巧度的计算方法。

This paper aims at the research of line words, which are composed of action morpheme and the noun morpheme .All these line words comes from "Modern Chinese Dictionary".

本文研究的对象是动、名语素组合成的离合词，研究的范围是《现代汉语词典》中所收录的能插入其他成份的双音节词语。

The tower plate utilizes stainless steel double bottom plates welded main beam ,by which welding deformation can be reduced,straight linear degree can be guaranteed, main beam rigidity as well as entire beam stability can be strengthened to resist horizontal orientation live load,and tower height can be lowered as well.
