查询词典 threshold exposure

Our experimental results shown that threshold voltage related hot only with the number of hecical turns ,hut a boundary-induced contraction or dilatation of the pitch also has a strong influence on it, at each regin, belong to a fixed n,the threshold voltage increases as the contraction of the pitch and the thieshold volage decreases as the dilatation of the pitch.

实验结果表明：阀值电压不仅与螺距数有关，而且与边界条件引起的螺距收缩和伸展有关，在螺距数不变的情况下，螺距的收缩使阀值电压提高，而螺距的伸展使阀值电压减小。

Firstly, there are less secure and efficient threshold schemes; secondly, the research on multi-secret sharing is rather weak; thirdly, usual verifiable secret sharing don't consider the partners' anonymity, while it is just people's expectation. Last but not least, the problem of variety on shares is becoming a more obvious restrict of efficiency, especially in the facets of the lost and being districted of shares. On the application of verifiable secret sharing, there are also two inadequates : on the one hand , verifiable secret sharing has been used in much threshold cryptography but in less verifiable signatures.

然而，经过认真总结、分析该领域目前研究的发展状况（具体结果将在第一章给出），我们发现在可验证秘密分享的研究方面，仍有下列四个不足之处：一是现有的安全、高效的门限方案不多；二是对多秘密分享的研究非常薄弱，在已有的文献中还见不到安全、实用的可验证多秘密分享方案；三是通常的秘密分享方案没有考虑秘密分享者的匿名性，而这恰恰是人们所希望的；四是秘密分享者的动态管理问题已经越来越明显的制约现有方案的安全，尤其是密钥份额丢失或被破坏时如何恢复更是没有被深入探讨。
