If two parties want to sign a contract C over a communication network, they must "simultaneously" exchange their commitments to C Since simultaneous exchange is usually impossible in practice, protocols are needed to approximate simultaneity by exchange partial commitments in a piece by piece manner The party of secondly sending commitments may have a slight advantage; a "fair" protocol must keep this advantage within acceptable limits The protocol for signing a contract is improved based on the research result of secure multiparty computation In this protocol, the parties obliviously transfer the signed bit and the committed bit; the other parties can prove the validity of this bit based on the confirming sub protocol, but he cant gain more information about the whole signature by accumulating the signed bit or the committed bit After the parties exchange the whole signed information, they declare the commitment about the signature respectively, and gain the whole signature of the other party At this moment, the party doesnt care about the advance quit of the other party, because he has gained the whole signed information Finally, it is proved that this protocol is quit fairness

在网络环境中解决合同签订问题需要保证信息交换的同时性，以前提出的协议都会给第 2个发送者部分计算特权，利用不经意传输协议则可以解决这个问题在协议执行过程中，参与者将合同的签名位以及他对签名位的承诺不经意传输给对方，对方可以利用验证子协议证明该位的有效性，但是他却不能通过位交换次数的增加获取更多的完整签名的信息；在完成签名位的交换之后，参与者分别宣布承诺，并得到对方对合同的完整签名；在宣布承诺时，协议参与者已经获得全部的签名内容，要么是签名位，要么是对方对该位的承诺，因此参与者并不需要担心对方提前终止协议在文章的最后利用多方安全计算的结论证明了该协议满足终止公平性1 引言两个参与者A和B想要通过网络协商签订合同C 为了保证公平性，参与者必须同时交换自己对合同的签名，然而在实际的网络环境中，想要完全同时地交换对合同的签名是不可能的，他们必须将签名分成若干块依次地执行，以保证大致的同时性但是这种方法依然存在着问题

At the end of the thesis,practically and realisticallysummarizing the studies concerning this topic,the author believes to put forward thenew viewpoints in following aspects,i.e.the"theory of three-phase"for thedevelopment of victimology;the trends of the worldwide development of the redress ofthe victims'rights;the new method to protect the victims,which balances theprotection between the victims and inflictors to resume the victims'rights by setting upthe protective measures such as the national relief and social supporting system for thevictims,which rarely connects with their rights and interests directly;the necessity ofthe redress of the victims'rights in 6 aspects;the deficiencies on the issue of theredress of the victims'rights in the aspects of academic research and legislation;theelementary reflects on the constitutional foundation for the protection of the victims;the two-side analysis on the regulations for the protection of victims in new penal law;the suggestion to establish the system for investigation,statistics and proclamation ofvictimization;the design to consummate the rights and redress of the victims inappealing procedures;the assumption to establish the social supporting system of thevictims in China,and soon.

在论文的最后，实事求是地总结了自己关于本课题的研究，认为在以下若干方面提出了个人的新见解。提出了我国被害人学发展的"三阶段说"；提出了世界范围内犯罪被害人权利救济的发展趋势；提出了通过建立对犯罪被害人的国家补偿制度和社会支援体系这样的与加害人权益不大发生直接联系的犯罪被害人保护措施，来实现犯罪被害人的被害恢复，以求得加害人与被害人权利保护平衡的犯罪被害人权利保护方式的新思路；从六个方面提出了我国犯罪被害人权利救济的必要性；从理论研究和立法两个方面指出了我国在犯罪被害人权利救济问题上的欠缺点，其中对我国犯罪被害人的理论研究作了反思，对犯罪被害人保护的宪法依据作了初步的探讨，对新刑事诉讼法关于犯罪被害人的保护的规定作了一分为二的分析；提出了建立我国的犯罪被害调查、统计和公告制度的建议；提出了为了防止被害人的第二次被害，而完善犯罪被害人在诉讼程序中的权利与救济的方案；提出了构建我国犯罪被害人社会支援体系的设想。等等。

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.
