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 analysis of some company"s hose failures indicates that 70% of the failures are caused by leakage between the hose and the fitting. In order to solve the hose fitting leakage problems of the hose assemblies, the experimentation has been carried out and the conclusion is that the fitting"s intension is not strong enough to prevent leakage. Plasticity theory is utilized to analyze the relationship of the working pressure of the hose, the connector material and the geometric dimensions. The calculation about crimp power of the hose assemblies is found, and the suggestions for assembly are given according to plasticity principle, also the program for analysis of fittings intension is developed with AutoLisp which runs in AutoCAD.

由某公司提供的胶管组合件故障资料分析，该公司的约70％胶管故障是由于接头处漏油造成的，为解决软管组合件接头处漏油的问题，本文通过试验得出了接头强度满足不了密封要求的结论，从塑性力学角度给出软管工作压力与软管接头的材料、几何尺寸之间的关系，对胶管组合件扣压力量给出计算方法，对扣压工序依据塑性力学原理提出指导意见，并在AutoCAD平台上以AutoLisp语言编写了接头零件的强度分析计算程序。

This method uses all noisy datapoints directly to implement triangulation and dispenses with smoothing and datareduction process, which may lead to loss of geometric character. Moreover, thismethod is of lower complexity than other triangulation and the amount of vertexes inmesh can also be calculated, so we can control the size of mesh in advance. At last, apractical example is given to prove its effectiveness.

这种方法利用全部数据点信息进行网格剖分，无需对数据进行平滑、精简等预处理，避免了因平滑或精简而丢失重要的几何信息的可能，这种方法不仅比现有三角网格剖分算法降低了算法复杂度，而且具有可以直接处理带有噪声的数据，网格规模可控，生成的三角网格形状较好等优点。

For the starry flounder this interpretation implies that a geometric difference (between fish that are mirror images of one another) is adaptive, that left-eyedness in the Japanese starry flounder has been selected for, which provokes a perplexing question: what is the selective advantage in having both eyes on one side rather than on the other?

对于星形比目鱼来说，这种说法暗示形状上的差异（同左右两侧对称的鱼相比）是适应性的，日本的星形比目鱼之所以眼在左侧，是选择的结果，但这又引起了一个令人困惑的问题：两只眼睛都在一侧比两只眼睛分在两侧具有什么选择性的优势呢？
