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 simultaneous depiction of everyday situations and hints of potential danger, which Hitchcock even spelled out by writing such lines as "Watch your back, there's someone there" on the posters for his movies, as well as the obliviousness of his protagonists to their immediate jeopardy, played masterfully on the fear that exists deep within our subconscious minds.

希区柯克还善于将日常生活的情境和潜在危险的端倪进行平行地叙述──他甚至在他的电影海报上写道："当心背后有人"，以及电影中的主角对于即将临近的危险的无知，都有力地刺激着在我们潜意识里深藏着的恐惧。

Nepetalactone, the primary component of catnip oil, were extracted by the using method of simultaneous distillation-extraction and separated by using silica gel chromatography column. To compare the repellency of nepetalactone and DEET on mosquitoes, topical bioassay method on the skin and a cage olfactometer were employed to assess the effective protection time and the spatial repellency.

采用同时蒸馏萃取及硅胶柱层析法从猫薄荷Nepeta cataria植物中提取、分离制得驱蚊有效成分假荆芥内酯，并采用个体涂肤有效保护时间测定法及风洞空间驱避效果测试法，对假荆芥内酯与避蚊胺的驱蚊效果进行了对比试验。

This paper considers simultaneous or Pareto optimization between the scheduling cost of all the jobs and the degree of this disruption.

为了保证先来顾客的需求和工件本身错位量的要求，着重研究这种使先来顾客的总目标函数值与工件错位量之间达到平衡的问题，即重新排序问题的Pareto最优解问题。

Simultaneous images are acquired on as many as 16 contiguous slices (21 slices with longer acquisition times) oriented along any suitable plane.

同步影像是后天就多达16项毗连片（ 21片较长的采集时间）为导向，沿任何合适的飞机。

The main works include five parts:(1) A modified K-means algorithm for optimizing the RBPNNs' structures was proposed;(2) The RBPNNs' structure optimization method based on the orthogonal least square algorithm was proposed that can greatly reduce the computation expense for the structure optimization;(3) Using the GA to perform the whole structure optimization of the RBPNNs was proposed in this thesis, which include simultaneous optimization of the hidden centers and the corresponding controlling parameters of the kernel functions.

主要工作体现在如下三个方面：(1)提出一种改进的 K-Means 算法；(2)提出了基于递推正交最小二乘算法的结构优化算法来训练径向基概率神经网络，从而大大减小了用于结构优化的计算开销；(3)提出使用遗传算法来实现径向基概率神经网络的全结构优化，即隐中心矢量和核函数控制参数同时优化，通过新设计的编码方式、新构造的适应度函数，充分发挥了 GA 的全局搜索性能，使得所优化的径向基概率神经网络的结构趋于最简。

In this case the Hilbert space can be decomposed into an orthogonal direct sum of partial wave subspaces, which are the simultaneous eigenspaces of the angular momentum operators J^2,J_3 and the operator K which describes the spin-orbit coupling.
