From the experiment and analysis, it can be seen that friction limits realization of high accuracy electro-hydraulic position servo system, movement of any gimbal brings disturbance moment to servo system of other gimbals and the disturbance moment causes error, and, resolution ratio error and setting error of feedback measurement element are directly added to servo system output.

通过实验和仿真可以看出，摩擦阻碍了转台电液位置伺服系统商精度控制的实现，任何一个框架的运动都会对其余框架的伺服驱动系统产生干扰力矩并引起伺服系统误差，反馈测量元件的分辨率误差和安装误差直接反映在伺服系统输出上，对伺服系统的精度有直接影响。

The purpose of this study was to examine the maximum value of pulling-force, momentum, ground reaction force, net muscle joint moment, the changes of muscle power on raising movement after sitting by different sitting distance patterns, which was measured from feet to a supposed vertical point on hip joint (25cm.35cm.45cm) during Tug-of-War.

中文摘要本研究针对拔河坐地起身动作，以足跟至髋关节点垂直地面位置的不同坐地距离（25公分、35公分、45公分）探讨起身动作之最大拉力值、冲量值、地面反作用力、净肌肉力矩、肌肉功率的变化，藉以了解坐地距离之变化对起身动作之生物力学影响。

The parameters were processed with SPSS for Windows12.0, and analyzed with repeated-measures ANOVA(α=.05).Results and Discussion:When the backpack load percentage during stair-down walking reaches 10%, knee landing angle, hip angle displacement, and vertical displacement of the center of gravity all have significant difference（pConclusion: Backpack load percentage has influence on human biomechanical performance during stair-down walking.

结果与讨论：下阶梯背重率达10％时，膝关节著地瞬间角度、髋关节角位移、重心垂直位移均达到显著差异(p＜。05)；当背重率达20％时，垂直分力与其产生时间、最大负荷率、踝关节肌肉力矩与角劲度亦达到显著差异(p＜。05)，此时人体必须透过增加踝关节角位移机制来降低垂直地面反作用力和最大负荷率及延后垂直峰值产生时间，藉以减少地面反作用力对人体所造成的冲击；而重心垂直位移也受到背重的影响而增加，以上均显示背重对人体下阶梯时下肢的负荷与影响。

And then, the effects of the hydrofoil type and the ratio of lift to buoyancy on the static stability of HYSWAS with fixed hydrofoils while foil borne is investigated. On the other hand, the static stability of HYSWAS on different operation states is also analyzed.

在此基础上，计算分析了基于非自控水翼的不同水翼型式及升力浮力比对HYSWAS翼航状态横向恢复力矩的影响规律，同时，研究了不同航行状态下HYSWAS的稳性特征。
