查询词典 discrete group

Active components belong to a group called discrete components, which perform a single function, e.g. regulate current or switch signals.

有源元件属于一个被称为分立元件的组别，完成单一功能，例如整流或转换信号。

Group signature ; discrete logarithm ; private key

群签名；离散对数；密钥

group signature ; discrete logarithm ; proofs of zero-knowledge ; digital signature ; security

因此，设计群组间可共享的安全的群签名方案引起了人们广泛的兴趣。

This problem is defined as: Given points X, Y on the elliptic curve, find z such that: X = zY The discrete logarithm problem over this group in a finite field is a good one way function because there are currently no known polynomial time attacks forsolving the problem.

这个问题是指：鉴于点X和Y的椭圆曲线，找到这样： X =模糊离散对数问题，这个集团在有限的领域是一个很好的方法之一的功能，因为目前没有任何已知的攻击forsolving多项式时间的问题。

The steady-state response of discrete vibration equation group is obtained using Duhamel integral in setting excavation unloading path and zero initial condition.

在给定开挖卸荷路径和零初始条件下采用Duhamel积分，得到离散振动方程组的稳态响应。

If taken the firms as the organization of cooperative game and taken the group rationality and discrete conditions into consideration, the distribution, based on the Shapley value of cooperative game, can meet the individual rationality and completeness conditions, and can give a more reasonable interpretation on the sources of the real firms' economic profits and the great differences between aggregate social labor incomes.

如果将企业视为合作博弈的组织，并考虑到群体理性和离散条件，按照合作博弈的夏普莱值进行分配则能够满足个体理性和完备性条件，也可以对现实中企业经济利润的来源和社会中劳动收入之间的巨大差异给予更为合理的解释。

Some examples are given in this dissertation. First, the coordinate values of a group of discrete points on the cam profile are achieved by conventional design method which are then used as measured data of the cam profile. Then the kinematic analysis of the cam mechanism is performed by the method developed in this paper. The reverse results are compared to the theoretic values.

本文以已知从动件运动规律的凸轮机构为例，利用正设计方法求出凸轮实际廓线一组离散点坐标值，并以此作为凸轮检测数据，运用本文提出的分析方法进行运动反求，并将反求所得结果与理论结果加以分析比较。

In this dissertation, two new proxy signature schemes from bilinear pairing are proposed, which are all based on discrete logarithm problem on GDH group. In the first scheme, the proxy signing ability can be revoked during the period of validity. Then, the malicious signer can not sign messages any more. Moreover, in this scheme secure channels are not needed.

本文基于GDH群的离散对数问题结合短签名的特点设计了两个代理签名体制，第一个体制可以在证书的有效期内撤销代理签名权，从而防止不诚实的代理签名者继续签名，而且无需安全信道。

In 1998, Lee and Chang proposed a group signature scheme based on the discrete logarithm problem.

1998年，L ee和 Chang提出一种基于离散对数问题的群签名方案。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
