Research on Precision Assembly Robot''''s Joint Torque Control Based on Current Measurement

A set of new current sensing device is used to realize joint torque control based on current measurement in a precision assembly robot's third joint. The output torque's model of the joint's brushless DC motor is founded. Disturbance factors and the compensated effect of the torque's closed loop based on current measurement are analyzed. Related simulations and experiments show that the system has good current tracking and anti-disturbances performance, which improve the force control performance of the robot in assembly.     

Present-Day crustal deformation field in China continent inverted from GPS observations, earthquake moment tensor and quaternary fault slip rates

Based on the bi-cubic Bessel spline function method, we have inverted the present-day crustal horizontal velocity field and deformation field in China continent by combining with 410 GPS observations, 327 seismic moment tensors of earthquakes and fault slip rates in China and its neighboring areas, and considered the geological and geophysical parameters at the same time. The results reveal that the crustal movement mostly takes on compression in SN-NE direction and extension in EW-NW direction in China continent. The continent is rotating southeast and takes on a clockwise rotation image from the west to the east, particularly in the southeast of Tibet and Chuan-dian area. Different blocks have different deformation in China continent. The south China, Ordos and Northeast block have good integrity.The deformation in the western part of China is obviously stronger than that in the eastern part. The strong strains are focused on the Himalaya, east Tibet,west Tian Shan and Chuandian block etc. The deformation at the joint of blocks is stronger than that within the blocks. The China continent deformation not only has the strike-slip faulting and extrusion feature but also has the crustal shortening and thickening feature.

简化太极拳对下肢关节的生物力学影响

通过对30例健康成年人在简化太极拳练习过程中下肢关节角度的测量及分析，发现在整个练拳过程中，受试者下肢关节角度均值的减小具有非常显著性差异。左右下肢关节平均屈曲30～40度即处于功能位，可以有效地提高下肢不同关节周围肌群的各种工作能力，有利于加强人体的行走和跑跳功能。另外，下肢动作弧度基本不受大腿长和小腿长的影响，正说明简化太极拳是适合于不同身高、男女老少皆宜的一项健身运动项目．     

试论我国有限责任公司资本制度

由于立法目的不同，在实践中我国就同一种有限责任公司类型下存在两种不同的资本组织形态，只有在法律上分清了两种资本制度的差异，才能将两者的优势结合起来，在实践中做好衔接和协调，现代化企业制度的建立做好保障。     

节理边坡渗流离散元模拟及边坡可靠性分析

采用定性研究和定量分析相结合的方法，对地下水对节理边坡稳定性的影响进行了较为全面的研究。首先采用离散元方法进行了节理边坡地下水流动的数值模拟；其次用不确定性方法——模糊点估计方法对有水和无水作用两种情况下的边坡稳定性进行了模糊随机可靠性对比分析。研究表明，地下水的存在使边坡的破坏面积增大，破坏概率剧增，边坡可靠性指标极大地降低，因此地下水对节理边坡稳定性具有不可忽视的作用。

叠合梁框架柱与整浇框架柱的对比分析

根据两榀叠合梁框架、一榀整浇框架的实测资料，采用对比分析的方法，对叠合梁框架柱和整浇框架柱的受力性能及变形特征进行对比分析。结果表明，叠合梁框架柱的截面应变符合磁截面假定，柱的承载力并不因梁的叠合施工工艺和二阶段受力而降低；柱端钢筋和混凝土的应变在弹性阶段均滞后于整浇框架，底层柱的反弯点低于整浇框架柱。
