This method undertakes comparative getting the area between the spare parts to equation of geometry of the face in model of CAD of different spare parts above all - surface contact relation and type, use amount coming back theory general face - the face expresses to be helix; relative to instantaneous motion next, the helix that goes up to many surface contact undertakes making operation,; of helix of the motion when making the opposite very short time between the spare parts is final, according to the spare parts abut concern plan and abut spare parts move relatively helix, undertook an analysis to assembling instantaneous of whole of the spare parts in the model to concern with drive movably, give out not between the method of calculation of helix of opposite instantaneous motion between photograph adjacent spare parts and them but the judgement method of drive sex.

该方法首先对不同零件CAD模型中面几何方程进行比较得到零件之间的面-面接触关系和类型，并应用旋量理论将面-面相对瞬时运动表示为螺旋；然后，对多个面接触上的螺旋进行交运算，生成零件之间的相对瞬时运动螺旋；最后，根据零件邻接关系图和邻接零件相对运动螺旋，对装配模型中零件整体瞬时可动性和驱动关系进行了分析，给出不相邻零件之间的相对瞬时运动螺旋计算方法和它们之间可驱动性的判定方法。

To prove one edge union of k-shell graph is cordial, firstly fix the labeling of vertex of common edge(label u with 0 and v with 1), then according to the value of the graph order n module 4 to class the k shell gaphs to four cases, and to divide to small cases in every shell graph.

本文研究k-贝壳图的亲切标号时，在固定了公共边上的点的标号(对u标号0且v标号为1)之后，我们采用如下方法：首先，以每个贝壳图的顶点数对4取模的余数来分类，这样就得到了四种(来源：d1ABC论文网www.abclunwen.com)不同情况的贝壳图；然后在每个贝壳图中再分情形进行标号；最后，通过证明得到这种标号方法是满足亲切标号的定义的，从而证明了k-贝壳图的亲切性，成功的解决了Sethuramam和Selvaraju猜想，证明了其正确性。

Those who do these actually very common, myself also does not look to go out it seems that have what tricks of the trade, but I still feel finally, all these is the effort that stem from a hobby and gives self-consciously, an article has read on stationmaster net before, probably means makes a station is do for the user, is not to please Baidu, in the whole process that is sealed so, I am right Baidu already not care a nut, because it does not have it to be indifferent to, the independent music that I just think an amount to is not much is confused gather just, so very active go adding content, change position according to need just.

做的这些其实都很平常，我自己也似乎看不出有什么诀窍，但最后我还是觉得，这一切都是出于爱好而自觉付出的努力，以前在站长网上看过一篇文章，大概意思是做站是为用户而做，而不是为了讨好百度，所以被封的整个过程中，我对百度已经毫不在意了，因为有它没它都无所谓，我只是想把为数不多的独立音乐迷聚在一起而已，所以很积极的去添加内容，根据需要改变布局而已。

On the net collect summed up the following respects, offer text to receive the main page on the site repeatedly, according to website size, more or less can webpage numerary receive all pages repeatedly even; For every join provides a brief introduction, in order to hints this one's duty allows the person that visit is about which on one hand; Exceed in website map and text the mainest crucial term alludes inside join, the help searchs theme of page of join of engine identifying place is about which on one hand; Help engine indexes a few dynamic pages, because a few pages will be of dynamic generation, if not be user behavior is called,will not show come, can put this join on website map, in order to help the dynamic page with engine main index; To make website map attracts the visit of network spider, the descriptive sex statement with go up certain must be written to use this connective keyword to have simple description at the back of join, but the use keyword that cannot transfer, can be just the opposite to what one wished otherwise; Because general spider catchs page of before 3 class only, so website map makes the same score better more, what point to here is logical way, is not physical method.

在网上搜集总结了以下几个方面，提供文本连接到站点上主要的页面，根据网站大小，网页数目的多少甚至可以连接到所有的页面；为每个连接提供一个简短的介绍，用以提示访问者这部分内容是关于哪一方面的；在网站地图和文本超连接里面提及最主要的要害词语，帮助搜索引擎识别所连接页面主题是关于哪一方面的；帮助引擎索引一些动态页面，由于一些页面将是动态产生的，假如不是用户行为调用将不会显示出来，可以将此连接放在网站地图上，以帮助引擎索引重要的动态页面；为了使网站地图吸引网络蜘蛛的访问，一定要在连接后面写上一定的描述性语句并使用此连接的要害词进行简单描述，但不能过渡的使用要害词，否则会适得其反；因为一般蜘蛛只抓前三级页面，所以网站地图越平越好，这里指的是逻辑路径，而不是物理路径。

Methods to rotor of centrifugal compressor"s condition monitoring and fault diagnosis are summed up. Peak-to-peak value is an essential reference value of centrifugal compressor"s condition monitoring, which is easy to implementation in practice. On the other hand, according to fault diagnosis, power spectrum and axis obit also works. The direction of eddyis gained from full spectrum, which is vital in fault diagnosis.
