In the second chapter, the stabilities of periodic regular gaits for six-legged robots walking longitudinally and laterally were systematically studied respectively, employing a hexpod's geometric model with outward extension of middle legs. Major progress and achievements reached are: a Both the necessary and the sufficient conditions for static walking of hexapods were established theoretically. b A generalized optimization method of gait stability was investigated. c For all feasible duty factor, stability-optimal gaits were obtained, with the expressions being of wide adaptation.

第二章系统分析研究了轴对称六足步行机器人在&中腿行程外置模型&下沿两个运动主方向运动时周期规则步态的稳定性及步态规划问题，主要取得以下三方面新的进展：（1）从理论上建立了六足步行机静态稳定的必要性定理和充分性定理；（2）探索了步态稳定性计算机择优的一般方法；（3）对于所有可能的有荷因数取值，从理论上证明静态稳定性最优步态的存在，并得到具有相当普遍意义的统一表达式。

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。

The experimental group received 10 weeks of walking exercise training, at 50 minuets per session, 5 days per week and at a exercise intensity limit between 60% and 70% maximum heart rate. The control group received ordinary special education curriculums. All participants completed three times of the PACER（Progressive Aerobic Cardiovascular Endurance Run）20-Meter Shuttle Run test and test for the average walking speed during 1600 meters:before the experiment started , after the experiment and the follow-up test at the fourteenth week of the experiment started. All results from these tests were recorded and analyzed by descriptive statistics; repeated measure t-test; the one way analysis of covariance .

VO2 was measured by Vmax 29 Series. The steps and energy expenditure was measured by pedometers. Results: When walking speed is 4.0kph, the relation between total steps and VO2 was significant (p＜.05). The Correlation coefficient was significant (p＜.05) between the steps and actual energy expenditure in all three walking speed.
