证实

The scheme is the improvementof confirmer digital signature. Also it is simpler and doesnt require the participation of the confirmer.

该方案是可证实数字签名的改进，比证实签名简单且不需要第三方的参与。

Furthermore, if it is necessary, the confirmer could convert confirmer signatures into standard ones such that the validity of these converted signatures can be publicly validated.

进一步地，在必要的时候，证实者还可以将证实签名转化为普通的数字签名，从而使得任何人都可以验证这些签名的有效性。

Without the help and cooperation of a designated confirmer,a verifier can not determine the validity of a confirmer signature.

验证者要知道一个证实数字签名的有效性，必须得到一个称为证实者的第3方的帮助与合作。

Meanwhile, a confirmer is able to transfer a confirmer signature into a general signature that can be verified by anyone if he or she can obtain it.

同时证实者具有转化一个证实签名为一个普通数字签名（即：可被任何人公开验证）的能力。

Considering the insecurity [3~5] or inefficiency[6] of current confirmer signature schemes,born of the canmenisch-michels formal model and structure,a new confirmer signature scheme based on DSA and RSA is proposed.

考虑到现存的证实数字签名方案或者是不安全的[3~5]，或者是低效的[6]，基于Canmenisch-Michels形式化模型和结构，提出一种新颖的完全基于DSA及RSA的证实数字签名方案。

When David Hale's first story about me was disproved, Starr let him change it until Hale finally came up with a version that was not disprovable.

当戴维·黑尔第一次指证我的话被证实是无中生有时，斯塔尔就让他不断修改，直到指证最终被证实可用为止。

After that things start to deteriorate: you get into Macroeconomics (feel free to skip this if you want) with its interesting theories about things like the relationship of interest rates to unemployment which, er, seem to be disproven more often than they are proven, and after that it just gets worse and worse and a lot of econ majors switch out to Physics, which gets them better Wall Street jobs, anyway.

你接下来学的是宏观经济学，如果你愿意，尽管跳过去，也不会有什么损失。宏观经济学开头的部分是利息理论，内容比方说是利率与失业之间的关系，但是怎么说呢，看上去这部分里面还没有被证实的东西多于已经被证实的东西。学完这部分，后面的内容越来越糟糕，许多经济学专业的学生实际上都变成在搞物理学，因为这样才能在华尔街上找到更好的工作。

Scientists have discovered the first confirmed Earthlike planet outside our solar system, they announced Wednesday.

科学家们周三宣称，已经证实发现了太阳系外第一颗类地行星。&这是太阳系外被证实的第一颗岩石行星。&

Methods The manifestations showed by MRI in 28 cases of intraspinal embryonal tumors identified by histology were retrospectively analyzed,and so did the 10 cases identified by CT scan.

经手术证实的椎管内胚胎性肿瘤共31例，余10例经CT扫描证实，回顾性分析其MRI表现。

In our study, 3 genotypies have been respectively demonstrated in UL139 and UL149 for the first time, and the corelations between certain genotypical structure and certain diseases were also proposed; The existence of the 3 genotypes of UL144 was foremost verified in isolates from congenital infants; Furthermore, the UL140, UL141 and UL145 genes were observed to be greatly discrepant to those had been described previously: comparing with Toledo, 231 nt are inserted in UL140, 2 more ORFs are obtained in UL141, and the UL145 ORF moves upstream by 90 nt. Except UL144, the sequences of 18 else genes in clinical isolates were submitted for the first time, and 479 sequences were assigned by GeneBank in total. Relevantly, 9 papers were published.

我们在学术界首次证实了HCMV UL139、UL149两个基因在临床分离株中分别存在三种基因型，发现了其中某个基因型的基因结构与特定来源的分离株存在一定的对应关系；首次在先天感染分离株中验证了UL144三种基因型的存在；首次证实了UL140、UL141和UL145等基因与原先认识的基因结构不同，其中UL140基因较Toledo株增加了231个碱基、UL141产生2个新的基因编码区、UL145 ORF较Toledo株前移90个碱基；首次或最先提交了除UL144基因外其余18个基因的临床分离株序列，本项目组共有479个HCMV相关基因序列被GenBank收录；发表研究论文9篇。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
