In this paper, the modeling theory of multi-rigid-body dynamics was thoroughly investigated in order to make up the shortcoming in the above modeling method. The major research achievements are as follows:①Based on the matrix of direction cosine between the body-fixed base and the reference base, and Poisson equation of a rigid body rotating, the coordinate transformation method for the modeling of treelike multi-rigid-body dynamics is derived. The method is very routinization and easy to use the computer to carry on the symbol derivation.

It change the normal method for "beginning control" and "goal control". With the development of living level, upholster is dispensability for indoor, the using of decorative material produce plenty of poisonous、baleful chemical substance. These substance make the air indoor into bad, and threaten the healthy in the door if these cumulate .What"s more it will reduce work efficiency. The past method of IAQA is subjective assessment or giving priority subjective assessment. But people will adapt to indoor environment due to settle in the door long-term, which it lead to incorrectness. So, we can"t only use subjective assessment for IAQ. In this article, the author bring forward the best and the reasonable assessing method ,which it is combining the subjective assessment to objective assessment.

随着生活水平的提高，室内装潢成为家居装饰不可缺少的部分，装饰材料的应用，会产生大量的有毒、有害化学物质，使得室内的空气质量变差，且长期累积会威胁室内人员的身体健康，导致工作效率低下，过去对室内空气品质的研究仅用主观评价方法或以主观评价为主对室内人员的主观感受做调查，但是由于室内人员对室内的环境具有适应性，从而造成评价的不准确，且过去对化学微污染物的影响没有定性的研究，因此，用该方法进行评价显然是不准确的，所以，本文提出用主观评价和客观评价想结合的评价方法对室内空气品质进行综合评价。

On the way, By giving the example as the names of the thing (such as silk silks etc.) with color and the basic colorific phrase associated with it, this text demonstrated a fact that the basic colorific phrases were evolved from the names of the thing that include the color, under the function of the come from the method that is borrowing the thing assumes the color, and expatiated the condition of the basic colorific phrase in Chinese language. Take the synthesize colorific phrase implied compliment or dispraiser as an example, explained the imagism of Chinese thought method how to influence the synthesize the colorific phrase, and do it by taking the food, metals and nature scenery makes the ratio at other Chinese thought method that is take shape to analogy as too. It expatiated the influence that the Han ethnologic culture result in the acceptation of the colorific phrase, pass on analyze the diverse the diverse metaphor meanings of colorific phrase and the opposite phenomenon of acceptation among them of, and the colorific etyma metaphor of "yellow","vermilion","purple","blue","green" and "white", under the premise that distinct the different between themetaphor meanings of colorific phrase and colorific etyma metaphor.

由此本文通过例举有色彩含义的事物专有名称及相应的基本色彩词，分析了基本色彩词是在"借物呈色"思维方式的影响下，由有色彩含义的事物专有名称演变而来的事实，并阐述了汉语基本色彩词的状况；以含有褒扬、贬抑语义的合成色彩词为例说明了汉民族"意向性"思维方式对合成色彩词的影响，以取食物、金属、自然界景物作比的合成色彩词为例说明了汉民族"取象类比"思维方式对合成色彩词的影响；在区分色彩词隐喻意义与色彩语素隐喻意义的基础上，通过分析色彩词的多元隐喻意义及其中的语义对立现象，并分析"黄"、"朱"、"紫"、"青"、"绿"、"白"等色彩语素的隐喻意义，阐述了汉民族文化对色彩词语义的影响。

Typical accident-causing" theories includes Heinrich" s Domino" s theory, its development by Bird, Adams and other people, progress of which is that it is deficiencies of management system that are the root cause in accident causation sequence. This is author" s idea resource and main method to produce the water traffic accident-causing theory . in addition, uncontrolled transferring of energy theory, applies widely in safety management scheme for water traffic; human error accident model can be used to analyze causes of collision accident and to take preventive measures; perturbation theory and multilinear event sequencing method is a very useful investigation method to water traffic accidents. All of these theories have contributed to the development of water traffic accident-causing theory. As to orbit intersecting theory, the paper thinks it extension of Domino s theory, although it exists independently.

有代表性的事故致因理论有海因里希因果连锁理论以及博德、亚当斯等人对该理论的发展，这些发展的主要进步是突出了管理缺陷是事故因果连锁中的基本原因，是本文分析和发展水上交通事故致因理论的主要思想来源和方法论；能量意外转移理论，广泛的应用在水上交通安全的各项具体管理制度中；人失误事故模型能用于指导对碰撞事故的原因分析和预防；动态变化理论及多线性事件连锁论对指导事故调查是较好的分析方法；轨迹交叉理论虽然以独立的理论形式存在，但本文认为其实质仍然是因果连锁理论的发展。
