因为64种可能的位排列仍不能满足十进制数（10个）、小写字母（26个）、大写字母（26个）和大量的其它字符（26个以上）编码的需要，所以设计者将6位BCD码扩充到7位和8位。7位二进制数可以提供128种不I司的排列(2 ')；8位二进制数可以有256种排列（2）。

To the same kind of rocks, the penetration rate increases with the increases of electric bit thermal power. When electric bit thermal power keeps fixedness, the penetration rate increases in various degrees with the increases of bit load in difference rocks. Increasing the bit load is beneficial to improve the quality of glass hole wall, but the bit load should not be too big.

We improve the protocol for signing contract 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 can't gain more information about the whole signature by accumulating the more 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 doesn't care about the advance quit of the other party, because he has gained the whole signed information.

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，参与者分别公开承诺，并得到对方对合同的完整签名；在公开承诺时，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，同时本文也利用多方安全计算的结论证明了该协议满足终止公平性。

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 can't 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 doesn't 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

作者中文名：曲亚东；侯紫峰；韦卫摘要：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。

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

The 4 nucleotides of DNA sequences can be further encoded with two - bit digits in which t he first bit is the base bit to encode purines and pyrimidines and the second bit is the functional group bit to encode the keto group and amino group. According to the degree of degeneracy of genetic codes and the two dimension distribution of molecular weights and isoelectricpoints of amino acids , a set of classification graph(Venn' s diagram) of amino acids can be obtained. It is suggested that the amino acids of high degenerate group are mostly small and simple, and constitute the transmembranic structure or the structural domains of protein molecules. So amino acids of high degenerate group might appear in the early evolution stage.

根据氨基酸遗传密码子的简并程度并以分子量及等电点作为氨基酸的化学特性坐标，作出其二维集合MP分类图，根据氨基酸的分类分析，可以认为：高简并度氨基酸多数是脂烃类和羟脂烃类的氨基酸，分子量比较小，分子结构比较简单，大部分为疏水性，主要组成跨膜结构或蛋白质的结构域，可能是出现较早的氨基酸；而低简并度的氨基酸，分子结构比较复杂，分子量比较大，多数是和蛋白质功能有密切联系的基团，可能是进化出现较晚的结构。
