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

According to the observation experiment at the Jiufeng station where there is smaller environment noise, the conclusions are drawn as follows.In the normal atmosphere, the observed value is about 500×10-5ms-2, which is greater than theoretical value about 30×10-5ms-2, and if in the low vacuum, the observational error about 2.3×10-5ms-2 is generated. The vacuum maintaining system in falling room can not work normally, which will yield 0.1~4.1×10-5ms-2 error to the gravimetric observation. In the case of that the measurement is in the stable geological conditions and the smaller environment noise, the action of vibration isolating spring is not obvious, but it yields greater effects on measurement accuracy.

通过在环境干扰较小的九峰站观测实验，得到如下结论：在正常大气压状态下所观测到的空气阻力影响约500×10-5ms-2，比理论估算值大近30×10-5ms-2，若在低真空状态测量空气阻力也将产生2.3×10-5ms-2观测误差；落体室真空度维持系统工作不正常，空气阻力也将对重力观测造成0.1~4.1×10-5ms-2的观测误差；在地质条件比较稳定，环境震动干扰较小的基墩上测量，隔震弹簧的作用对观测结果影响不明显，但对测量精度影响较大。

In 4 cases, the cavities were full of perilymph. We could find that the cavity was irregularly round-shaped, about 6.5 mm in diameter, with thin mucosa adhere to the cavity wall. In the center area, around the internal acoustic meatus fundus, there was a horseshoe- shaped cystic structure about 3 mm3, which was a combined structure of the saccule, utricle and scala media. In 1 case, there was little perilymph in the cavity, with about 1.5 mm thick soft tissue and granulation adhere to the wall. The saccule, utricle and scala media were not recognizable.
