交换

While 30μmol·〓 FRCRSFa and 10μmol·〓 E-4031 were dialysed intracellularly via the patch-pipette, FRCRSFa significantly decreased 〓 exchange current and there was no the further decrease after adding FRCRSFa in the perfused solution with the same concentration, whereas E-4031 dialysed had no effect on 〓 exchange current, but a obvious increase of it occurred when adding E-4031 to the perfused solusion with the same concentration.

分别将30μmol·〓的FRCRSFa和10μmol·〓的E-4031加入微电极内液中，FRCRSFa显著抑制了〓交换电流，当在细胞外灌流液中加入同样浓度的FRCRSFa时无进一步抑制；而胞浆内的E-4031对〓交换电流无显著作用，而在灌流液中加入同样浓度的E-4031后，却显著增强了〓交换电流。

本文提出一种新型的具有交换功能的点对多点通信系统，给出了交换网络结构与控制系统设计方案，结合SCPB-TDM/TDMA多址方式和特定的系统传输帧结构设计，讨论分析了实现中心站和用户站两级交换控制所需解决的问题，包括信令系统、按需分配系统及话务容量分析等。

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。

The paper holds the idea that, parallel bus can;t adapt to high-speed transfers due to self-limitations, and high-speed serial point-to-point bus will substitute for traditional parallel bus; data transfer will not be carried out simply by drive circuit and parallel bus, but by special high-speed serial bus; the traditional mode of single bus loading multi-device is disappearing, and a centralized switch module is replacing the bus function in a mode of one switch module connecting all devices via high-speed point to point serial bus.

文章认为并行总线由于自身缺陷，已经不适合进行高速传输，高速串行点对点连接将代替传统的并行接口；数据交换也不再是简单地通过驱动电路和并行数据线进行，而是通过特殊的串行高速总线连接；传统的在一条总线上同时挂载多个设备的模式正逐渐消亡，总线功能已被一个集中式的交换模块取代，而交换模块和各个设备都是通过高速串行点对点的方式进行连接。

A performance or return promise is bargained for if it is sought by the promisor in exchange for his promise and is given by the promisee in exchange for that promise.

受诺人的履行或诺言是磋商交换的对象，指诺言人为了得到它而以自己的诺言作交换，受诺人付出它是为了与诺言人的诺言作交换。

Direct exchange being impossible, and indirect exchange being purposeless from the individual point of view, no exchange would take place at all.

因为直接交换是不可能的，而间接交换从个人观点中看，是漫无目的的，交换就根本不会发生。
