On this foundation, application changes control of structural slippery model designed dimensional machine theoretically inertial space contrail coordinates brachial carrier attitude and extreme ungual hand of motion change; of program of control of structural slippery model to overcome afore-mentioned changing controller of structural slippery model trembles brace up defect, add designed an ambiguous controller, with coming to dynamic adjustment to change according to control output of the system the structure slips the coefficient that the fast approach such as modular controller leads, achieve thereby make sure the system is had already answer quickly can eliminate original controller to have again tremble brace up the purpose of defect.

在此基础上，应用变结构滑模控制理论设计了空间机械臂载体姿态和末端爪手惯性空间轨迹协调运动的变结构滑模控制方案；为了克服上述变结构滑模控制器抖振的缺点，附加设计了一个模糊控制器，以根据系统的控制输出来动态调节变结构滑模控制器等速趋近率的系数，从而达到既保证系统具有快速响应又能消除原有控制器具有抖振缺点的目的。

The frictional heat energy was concentrated on the thermal effect layer with the thickness of 4 mm, The temperature gradient of contact surface is the highest, and decreased rapidly with the radius direction of the lining's groove. The temperature gradient and TEL's thickness increased with the increasing of the sliding speed. The temperature decreased rapidly with the radius direction and also with the increasing of center angle of the lining's groove. The sliding speed and distance are obtained under two sliding conditions when the lining fails, which supply the theoretical basis with the antislip design of friction hoist.

摩擦热量集中在热影响表面层，其厚度仅为4mm，接触表面温度梯度最大，沿绳槽径向迅速减小；温度梯度和热影响表面层厚度随相对滑速的增大而增大；衬垫温度沿径向急剧降低且随圆心角增大而减小；并得到了2种滑动工况下衬垫失效时的相对滑速和滑动距离，为摩擦提升防滑设计提供理论依据。

These include inflammatory arthritides such as rheumatoid arthritis, ankylosing spondylitis and reactive arthritis,99 101 synovial impingement,meniscoid entrapment, chondromalacia facetae, pseudogout,synovial inflammation, villonodular synovitis, and acute and chronic infection.102 106 Intrafacetal synovial cysts can be a source of pain because of distension and pressure on adjacent pain-generating structures, calcification,and asymmetrical facet hypertrophy.107 110 In a retrospective review of MRI scans in 303 consecutive patients with LBP, Doyle and Merrilees111 found that9.5% had facet joint synovial cysts, the large majority of which were located posteriorly.

Methods 47 patient were treated with pedical screw fixation and spinal fusion for grades I and 2 isthmic spondylolisthesis. In 22 patients posterior lumbar fusion was performed, and in 25 patients posterior lumbar interbody fusion was performed. Two groups were compared for clinical outcome, radiographic date (include: correction of slippage, disc space height, segmental lordosis and fusion rate) and complication rate.

The results indicate that in the synchronizing condition the MRF is unyielded, every point of MRF in the flow field has the same angular velocity. Under the slipping condition, with the increase of magnetic field or the decrease of slip speed, MRF may transfer from whole yield to partial yield. When the MRF wholly yields, the angular velocity of MRF increases nonlinearly with its radius, the non-linear distribution becomes more obvious as the magnetic intensity in the working gap increases. When the MRF partially yields, the yield region expands with the decrease of magnetic intensity or the increase of slip speed and the unyield region always reaches the driven rotor. The transfer torque of MRTD increases with the increase of the external magnetic field, but the transfer torque maintains a constant value approximately with the variation of slip speed at the same magnetic intensity.

研究结果表明，在同步工况下，传动装置流场中磁流变液未屈服，各点角速度相同；在滑差工况下，随外加磁场的增大和滑差转速的减小，磁流变液逐渐从完全屈服向部分屈服转变；磁流变液完全屈服时，磁流变液角速度随半径呈非线性增加，工作间隙中磁场越强，流场的非线性分布越明显；磁流变液部分屈服时屈服区域随外加磁场的增大而减小，随滑差转速的增大而增大，未屈服区与主动转子相连；稳态下磁流变传动装置传递的转矩随外加磁场的增加而近似呈线性增大，但在相同外加磁场下，传递转矩基本不随滑差转速改变而改变，表现出良好的恒转矩特性。

They were divided into two groups:elderly group(with 3 or more centrums hyperosteogeny) and younger group(with less than 3 centrums hyperosteogeny). Then they were evaluated according to Meyerding method and analyzed by χ2 and Fisher accurate probability examination.Results Among the younger group,any degree of lumbar spondylo-listhesis had all prominent relationship with spondylolysis.
