查询词典 threshold

The concentration-response curves for ATP with and without preapplication of hypotonicity showed that preapplication of hypotonicity shifted the curve downward; maximal amplitude of IATP with hypotonicity decreased by 25.26±2.41%, while the threshold value remained unchanged; the EC50 value of the two curves were very close(1.19×10-4M vs 1.33×10-4M).

3在低渗透压(260mOsm)环境下，ATP-激活电流的浓度反应曲线明显下移；阈值和最大反应浓度不变，EC50为1.19×10-4M，与单独加ATP时的1.33×10-4M基本一致；而最大反应浓度时的ATP电流幅值减小了25.26±2.41%(n=6)。

We propose a dynamic identity authentication scheme through a theorem about relative prime numbers, which can prevent replay attacks from taking place. In addition, we present a threshold signature scheme without a trusted party by use of joint secret sharing technique. Finally, the security flaw in an enhanced password authentication scheme is pointed out and the security of an enhanced key agreement protocol is analyzed.

首先基于一个关于互素数的定理设计了一个动态身份认证协议，该协议使攻击者不可能通过回放攻击来假冒用户；利用联合秘密共享技术设计了一个无可信中心门限签名方案；最后，分析了一个改进的身份认证协议存在的安全漏洞，以及一个改进的密钥协商协议的安全性。

First of all, in recent years, an abundant supply of high-grade property is already a lot of projects to tend to a reasonable profit; Secondly, the credit enhance the threshold, the state's strict control of land makes the supply of high-end properties relative reduction, supply reduction and demand constant, high-end property prices will be the phenomenon; Third, the investment property is currently mainly concentrated in the commercial, high-end luxury apartments and other property, will make bank loans to enterprises in strict review of the project, thereby affecting the project normal operation, reflected in the market, a considerable number of projects the market will be delayed because of funding problems.
