Afterwards, we propose a new constant coefficients measurement method in dynamic equation of robot manipulators, this measurement method includes three groups of experiments: group one, let each joint of robot manipulator keep static to measure the constant coefficients in gravity term of dynamic equation and Coulomb frictional torque, group two: let only one joint of robot manipulator move at a constant velocity to measure the viscous frictional coefficient and constant coefficients in effective inertia of dynamic equation, group three: let only one joint of robot manipulator move at constant acceleration at a time to measure constant coefficients in Coriolis and centrifugal term and coupling inertia of dynamic equation.

让操作器单个关节恒速运动，在对驱动系统中传动机构，减速装置和电感系数综合考虑的基础上，这组实验对粘滞摩擦系数及有效惯量中常数系数进行测量。这种测量方法只要求旋转关节的驱动电机施加恒定电压，回转关节驱动电机施加正弦波电压。3。让操作器单个关节恒加速运动，这组实验测量动力学方程中哥氏力、离心力项和耦合惯量项中的常数系数，这种测量方法只要求单个关节匀加速运动，而其它各关节保持静止，这种测量方法虽然要求关节匀加速运动，但不必进行关节角加速度检测，而只需进行关节角位移和角速度检测即可，输入量直接给定为输入电压。

The experimental conclusion determined that if the knee joint angle can be kept at 140-150 in the buffer jump at various liftoff heights, and the coax joint as well as the knee joint can be larger than 170 at the instant liftoff, an optimal jump can then be achieved.

Based on the selection rules on the rotational joint fit comer, spherical joint fit comer and parallel bar interference, which are application-based, the relationships between those restrictions and mechanism parameters are deduced in the mathematic functions, especially for the compound spherical joint.

文章摘要：以6-RSS型并联机构为研究对象，建立解析形式的反向运动学方程，给出考虑驱动副转角范围、球副转角范围、连杆干涉等约束条件时的反解选取准则，推导出每种约束表达与机构参数间关系，特别是复合球副独特的附加约束表达。

The present state of artificial joint material research and joint market demand were described.The development of the β titanium alloys with high strength,plasticity and low Young′s modulus has become the focus of artificial joint material.

讲述了目前人工关节的市场需求情况及人工关节材料的研究现状，提出开发强度高、塑性好、弹性模量低的β型钛合金成为各国研究的重点，同时开发出了具有自主知识产权的近β型钛合金TLM(Ti-Zr-Sn-Mo-Nb)。

In the third part of the article,it rethink the joint tenancy type of partnership porperty and inheritance from a new view.the inheritance belongs to the financial group but not the joint tenancy of inheriters.The porperty in the partnership also is not the joint tenancy of the partners,when some kinds of partnship are the civil body,the porperty should belongs to the partnership but not the partners.

文章第三部分，以一种全新的视角审视共同共有适用弱化在"遗产共同共有"和"合伙财产共同共有"的体现，认为遗产继承中的财产属于财团性质而非继承人之间的共同共有，合伙财产也不是全属于合伙人之间的共同共有财产，当部分合伙符合民事主体的要件时，应认定为合伙主体的财产而非各合伙之间的共同共有财产。

Artificial joint replacement basically meets the physical requirements of joint function, maintains majority of normal range of motion, and restores majority of joint function. Moreover, the prosthesis source is abundant with no rejection.

Joint friction and micromotion should inevitably form the biofilm and debris around the prosthesis, which will provide a breeding ground for the propagation of pathogenic microorganisms. On the contrary, the destruction of bone around the joint caused by infection is one of the reasons of joint sinking.

在一定条件下，术后关节感染与假体松动又是相互促进的，关节的摩擦和微动，必然会在假体周围形成界膜和微粒，这就为病原微生物的繁殖提供了条件；反之，关节周围的感染所造成的骨破坏，也是关节松动下沉的一个原因。
