The mechanical leveling system can realize accurate leveling of the platform by servo-motors and drive system, braking by motor brake (worm and worm wheel system features self-locking) to permanently lock the support system after leveling. Bellows outside outriggers functions sealing and dust-proof of the screw rod; guiding slide blocks are used to prevent screw rod from rotating; displacement sensors installed inside drive system deliver real-time information to determine platform height; load cells deliver data of loading conditions of every outriggers in balancing.

平台机械调平系统通过伺服电机、传动系统可实现对平台的精确调平，并通过电机制动器制动（蜗轮蜗杆系统也具有自锁特性），对调平后的支撑系统进行长期锁定；支腿外部的波纹管可实现丝杠的密封防尘；支腿上部的导向滑块可防止丝杠自转；支撑驱动系统内部安装的位移传感器随时传递信息确定台面的高度；荷重传感器为平衡各支腿的受力状态传输数据。

With the vertical time sequence results computed by the monitoring data (until Aug, 2008) from 28 GPS stations of continuous observation in Tianjin and Beijing Area, the paper analyzes the variation characteristics of vertical component of each GPS continuous stations, calculates the vertical movement velocity of GPS stations in Tianjin and Beijing Area of 2007~2008, compares with the vertical deformation velocity calculated by leveling of 2007-2008 in Capital Circle Area; Furthermore, searches GPS stations nearby the leveling route, corresponding to the first and second leveling time period, calculates the section plane of GPS route, analyzes and compares the section results of GPS and leveling of 2 time periods.

利用北京和天津地区的28个GPS连续观测站资料（资料截至2008年8月）计算得到的垂直向时序结果，分析各个GPS连续观测站垂向分量的变化特征，计算得到2007~2008年北京天津地区GPS站垂直运动速率，并与水准测量计算得到的2007~2008首都圈地区垂直形变速率进行比较；通过寻找水准测量路线附近的GPS站点，相应于水准的初测和复测时段，计算得到GPS路线剖面图，将GPS与水准2个时段的剖面结果进行对比分析。

According to the plane cross section assumption, configuration of a rod is expressed as a history of the cross section with arc coordinate. A special solution which stands for equilibrium in straight line state is obtained from differential equilibrium equation. Linear perturbation equation is derived and its general solution is obtained in which the integral constants are determined by constrained conditions at two ends of the rod. The condition of existence of non zero solution of the integral constants gives to the Greenhill formula of exact elastic rod model, which shows that the boundary of stable area is a closed curve and of symmetry, and inference of shearable and extensible to stability of the rod is depend on three factors: difference between flexibility of shear and extension of a section of the rod, bending stiffness and the length of the rod.

基于平面截面假定，弹性杆的位形表达为截面的弧坐标历程，根据平衡微分方程得到了两端受力螺旋作用时的直线平衡特解，导出了线性化扰动方程及其通解，积分常数根据两端铰支时的边界条件确定，并根据其存在非零解的条件得到弹性直杆精确模型的Greenhill公式，表明稳定域为一对称的封闭区域，拉/压和剪切对稳定性的影响取决于：拉/压柔度与剪切柔度之差，抗弯刚度和杆长这三个因素
