The static model of torsion joint is based on that of bending joint. The effects of structure parameters inside air pressure, initial angle, rube average radius, rube shell thickness on the turning angle are analyzed and the following conclusions are drawn: the relationship between the angle of torsion joint and the inside air pressure is basically linear, the angle of torsion joint increases with the initial angle and rube average radius, the angle of torsion joint decreases while the rube shell thickness increases. The kinetic equation is built for torsion joint. Simulating experiment implies that the time of inflating and deflating process is extremely shorter than that of kinetic process. So the pneumatic process can be ignored in actual system design and control. The factors that affect the dynamic features of torsion joint, such as shell thickness of rubber tube, average radius, initial angle, connector's outlet area, moment of inertia and viscous damping coefficient, are analyzed and the following conclusions are drawn: the change of rube shell thickness has no effects on the dynamic process of FPA inside air pressure while greatly affects the turning angle of torsion joint; when the rube shell thickness is small, the torsion joint has a bigger turning angle, no overshoot and long risetime, when the shell thickness is big, the turning angle of torsion joint is small, but has high response speed, overshoot and low shock; when the rube average radius increases, the turning angle of torsion joint increases and the overshoot increases too; when the initial angle of torsion joint is big, the turning joint is big, the overshoot is small and shock is low, but the risetime is big; the connector's outlet area affects the dynamic process of FPA inside air pressure greatly, but has no effects on the dynamic process of turning angle; moment of inertia and viscous damping coefficient have no effects on the dynamic process of FPA inside air pressure, but affect the dynamic process of turning angle greatly.
在弯曲关节模型推导的基础上，建立扭转关节的静态模型，并分析了扭转关节内腔压力，初始转角，橡胶管平均半径，橡胶管壁厚等参数对关节转角的影响，得出扭转关节的转动角度与充入FPA内腔的压缩气体压力之间基本呈线性关系，扭转关节的转角随初始角度和橡胶管平均半径的增大而增大，扭转关节的转角随橡胶管壁厚的增大而减小的结论；建立了扭转关节的动力学方程，仿真实验表明FPA的充放气过程与扭转关节的动力学过程相比时间极短，在实际系统设计和控制过程中可以忽略不计；分析讨论橡胶管壁厚，平均半径，初始角度，气体节流口面积，转动惯量，粘性阻尼系数等因素对扭转关节动态特性的影响，得出橡胶管初始壁厚的变化对扭转关节FPA内腔压力的动态响应几乎没有影响而对关节转角的响应曲线影响比较明显，壁厚较小时，关节可以得到较大的转角，并且转角的响应曲线没有超调，但上升时间长，壁厚较大时，关节转角变小，响应加快，但是有超调和轻微振荡现象，橡胶管平均半径越大，得到的关节转角越大，但是转角响应的超调量也随之增大，FPA的初始角度越大，关节的转角越大，并且超调量减小，振荡减弱，但是上升时间增大，管接头出口面积的大小对关节FPA内腔压力的建立过程影响较大，但对关节转角的动态响应几乎没有影响，转动惯量和粘性阻尼系数对FPA内腔压力的动态过程几乎没有影响而对扭转关节转角有较大影响等结论。

尤其在查处未知干扰信号源方面，为了确定该信号源的地理位置，常用两个或多个固定测向站联网进行测向定位，现有的算法虽然在扩大测向范围和提高定位精度方面起到了一定的作用，但是由于各种误差因素的存在，仍不可能使多元固定站交会定位的结果与被测目标位置完全重合或具有很小的偏差；而是存在一个不小的概率椭圆误差区域，因而无法精确确定被测目标的真实位置。

Results The respiratory motion influenced the actual dose of target. When the respiratory motion range increased, the area of dose was more extensive, the max dose of the target was lower. The respiratory motion was smaller than half height-width, the shape of higher dose was ellipse and the direction of short axis was the same as that of respiratory motion. The respiratory motion was bigger than half height-width, the area of higher dose became longer and the direction of ellipse long axis was same as the respiratory motion. When the respiratory motion range increased, the value of Fv was bigger.

Take gaining profit at Shanghai Future Goods Exchange Centre for example, investors gained profit from in-stock gold price at 22 Yuan/g on January 9th 2008 the first day of Shanghai 0806 contract future gold went on the market. Except financial dect 1.665 Yuan/g, 2% of open interest freeze consumption, different commissions 1.2 Yuan/g, investors could have opportunities of gaining profits only when material future goods price is less than the golden area illustrated in the above pictures on the first open day on the market. If investors could make sure future goods price expiration and the actual price shock is limited in a scale while the scale shock is limited in the golden area, the investment risks will greatly decrease. Syphonage theory deems that if investors could select a golden area whose shock scale is limited in the golden area and select a package whose profit aim shocks stay far from risk boundary. In most cases, to say that profit gaining exchange cannot get infinite profits as expected is not an exaggeration, due to different national gold exchange system. The result of profit gaining exchange is to limit the lever percentage of risk investors. In actual profit gaining process, investors should choose suitable type to operate.
实际运作时应主意国家黄金财政政策限制了某些类型套利获利空间，以在上海期货交易所套利为例，投资者在2008年1月9日上海黄金期货0806合约上市首日，利用和上海黄金交易所黄金现货价格22元/克的价差进行套利，除去财政扣减1.665元/克、开仓冻结资金利损2％、各项佣金手续费1.2元/克，如黄金期货上市首日套利为例，九五金和黄金期货0806品种在上海进行期现套利时，只有当实际期货价格小于上图期现套利示意图金色区域时，套利者才有机会获利，例如投资者确定未来期货价格到期时，实际价格波动范围在一定区间内，同时该区间波动幅度不会超出图中金色范围，则投资风险会大幅减小，虹吸理论认为投资者a尽量选取能创造较大范围金色区间，并且套利目标波动距离远离风险边界的套利组合进行套利，很多时候套利交易在有些国家黄金交易制度等因素影响下，并不能获得传说中无限的利润空间，这决非危然耸听，套利交易的结果等于是缩小了风险投机者的风险收益杠杆比例，在实际套利过程中，投资者应选择合适的品种进行操作。
Since the top of stone pillars is lowering at a rate of 10.4 mm/ka, and the bottom deepening 26.17 mm/ka, therefore, the actual height increase of stone pillars is 15.77 mm/ka; considering that the soil erosion rate in the area of Lunan Stone Forest is 650 mm/ka, the visible height of stone forest is increasing at a rate of 639.6 mm/ka, and soil, an extremely significant factor for the heightening of stone pillars, is rapidly becoming thinner and thinner at a rate of 623.83 mm/ka.
在现代自然条件下，路南石林顶部的剥蚀降低速度为10.4mm/ka，土下的溶蚀加深速度为26.17mm/ka，石林的实际高度仍以15.77mm/ka的速度在拔高；表土剥蚀速度为650mm/ka，石林的可见高度现正以639.6mm/ka的速度增加，土壤正以623.83mm/ka的速度快速变薄，表明虽然目前石林的可见高度仍在增加，但其发育的最佳时期已经过去。

The result shows that the fresh surfacing area was smaller than abrasion mark area, and it was bigger than actual contact area. The wear of Zr-4 alloy against Al2O3 in Na2SO4 solution was ten times higher than that in air and pure water, but its coefficient of friction was smaller. The wear of Zr-4 alloy against Al2O3 in pure water was equal to the numeric value of the Zr-4 alloy against Al2O3 in Na2 SO4 solution given the -2000 mv potential. When Zr-4 alloy was in corrosion environment, the wear increased in proportion to the increase of the potential, and the fretting wear and fretting corrosion resulted mainly from electrochemical action.

Then, based on thermal-structure coupled theory, the thermal-structure coupled of the clack box which suffered from mechanical and temperature load was analyzed using the powerful software ANSYS. The clack box`s temperature field and stress field as well as the stress spectrum of danger area in actual working condition were obtained. Finally, based on crack initiation and crack extension theory, the clack box`s fatigue life was predicted.
