To enhance security in Ad-Hoc networks,it is important to evaluate the trustworthiness of other nodes without centralized authorities.In this work,authors focus on the evaluation of trust evidence in Ad Hoc networks.First,the authors introduce the metrics of the trust,the evaluation process is modeled as a path problem on a directed graph,where nodes represent entities,and edges represent trust relations.Using the theory of semirings,a trust evaluation model based on semiring（TD-SEMIRING） is developed,then two nodes can establish an indirect trust relation without previous direct interaction and introduce the application of this model in route election.At last,the feasibility of this model is analyzed.

讨论了对可信事件的评估：首先介绍了可信的相关概念和相关的特性；接着评估过程被建模成一个在有向图寻找最短路径的问题，在该有向图中结点表示实体或者用户，边表示可信关系，通过使用半环理论，建立了一个基于半环的可信性评估模型TD-SEMIRING，在两个以前没有进行相互操作的实体之间建立间接的可信关系，介绍了这个模型在路由选择当中的应用；最后，通过仿真实验，验证、分析了该模型的有效性。

The next year I did better still, for I spaded up all the land which I required, about a third of an acre, and I learned from the experience of both years, not being in the least awed by many celebrated works on husbandry, Arthur Young (10) among the rest, that if one would live simply and eat only the crop which he raised, and raise no more than he ate, and not exchange it for an insufficient quantity of more luxurious and expensive things, he would need to cultivate only a few rods of ground, and that it would be cheaper to spade up that than to use oxen to plow it, and to select a fresh spot from time to time than to manure the old, and he could do all his necessary farm work as it were with his left hand at odd hours in the summer; and thus he would not be tied to an ox, or horse, or cow, or pig, as at present.

第二年，我就干得更好了，因为我把总需要量的全部土地统统种上了，只不过一英亩的三分之一，从这两年的经验中，我发现了我没有给那些农业巨著吓倒，包括亚瑟·扬的著作在内。我发现一个人如果要简单地生活，只吃他自己收获的粮食，而且并不耕种得超过他的需要，也不无餍足地交换更奢侈、更昂贵的物品，那末他只要耕几平方杆的地就够了：用铲子比用牛耕又便宜得多；每次可更换一块新地，以免给旧地不断地施肥，而一切农场上的必要劳动，只要他夏天有空闲的时候略略做一做就够了；这样他就不会像日前的人们那样去和一头牛，或马，或母牛，或猪猡，捆绑在一起。

Today, i was waitering at the restaurant that i work at when i collected a credit card bill that was worth ＄120 and a big zero on the tip line.

今天，我在我的饭店工作，收到了一张120美刀的信用卡账单，可是&小费&那一栏里面啥都木有。

There are at least two reasons to say, the first reason, there is not enough and consummate policies to protect private enterprise"s benefit and private enterprise can"t get the same political treating as government enterprises. The another one, the system of most private enterprise is non-consummate, such as not consummate at the field of management structure, bestirring and inhibiting rules, stratagem and management, and result in the poor core competence. For examples, some leaders of private enterprise are arbitrary and dont believe in other people to manage work; only trust his connection and private friends to be in charge of management; some decision made according to feeling only, not according to scientific judgment; in defect of bestirring and inhibiting rules...so on.

究其原因，一方面是因为目前中国保护民营企业的制度机制还不完善，民营企业还无法取得和国营企业相同的政治待遇，另一方面是由于多数民营企业自身制度缺损，表现在企业治理结构、激励约束机制、战略管理等方面极不完善，从而造成的核心竞争力普遍低下，如：民营企业家决策中独断专行，对他人不能放心放权；民营企业经营管理中太相信亲戚和朋友；部分决策听任感觉，缺乏科学论断；缺少激励约束机制等。

The research work in this dissertation aim to apply the advanced technique in practice, that ramifies three parts: at first, the basic study of the computer vision, especially the stereo vision, include their technical mechanisms, methods and algorithms resolves the same technical problems of endoscopy and ferrograhpy based on stereo vision. Secondly, the endoscopy of engine fault inspection based on stereovision is researched and the system faced to this application is developed, thus the problems of stereovision applied to macroscopical images such as endoscopic images are resolved in method and computation. In addition, inside scenes are reconstructed and typical damages of engine inside are analyzed. Thirdly, the investigations of system formation, methods applied and algorithms study of debris analysis based on stereovision is carried out. Thus the problems of stereovision applied in debris analysis are resolved mainly. Furthermore, the integrated method combine with 3D symbolic parameters is studied and discussed for the recognition of debris configuration in pilot.

This one at times felt like an economics class with simple explanations of how credit markets work, and at others like a late-night cable TV commercial:"The average family who refinances today can save nearly $2,000 per year on their mortgage."

本次有时感觉像一场经济课，对信用市场的运行作解释，其他部份像是午夜的有线电视商业评论：&今天平均每个家庭能每年存2000美元为他们的抵押品再融资。&

SiC polytypes of 6H and 15R and a transition zone between the two were observed under HREM and TEM and discussed from the point view of the crystal structures; the clear evidence of Al〓C〓 nucleated in the SiC particle was provided, indicating the aluminum penetrating the SiC grains is already carbon-saturated and, consequently, Al〓C〓 crystals grow in the particles wherever a temporary local supersaturating is produced; The experimental observation indicated that the types of the interface between SiC and Al are variable and the distribution feature of reaction product, Al〓C〓, were also given in the present work: to be nucleated on SiC, to be aggregated at SiC/Al interface zone or to be aggregated at the crystal boundaries.

通过高分辨透射电镜，本文观察到SiC增强体中6H和15R同质多晶现象及6H-15R SiC转变区，以及另外一种无序的SiC同质多晶，并从其晶体结构的角度解释了6H和15R在晶体内共存的现象。通过高分辨透射电镜，本文给出了Al〓C〓在SiC颗粒内部形核的明证，表明Al〓C〓形核是Al渗透到SiC颗粒内部在C过饱和处在SiC的（0006）面上而形核，而且一种可能的位相关系为A1〓C〓[11〓0]∥SiC[11〓0]。研究结果同时给出了SiC/Al复合材料的界面反应产物A1〓C〓的分布特征：在SiC上形核并生长，聚集于SiC/Al界面去附近，或者聚集于晶界上。
