查询词典 even permutation

The odd L yrast states can be either symmetric or antisymmetric, while the even L ones are only symmetric under the permutation of the two components.

我们证明了，对于奇角动量和偶角动量，yrast态有不同的行为，即在两分量间的置换下，奇角动量态可以是对称的，也可以是反对称的，而偶角动量态仅存在对此解。

Recently, baidu is more unpredicatable to the permutation of Serp, whether is the acquiescent home page that does not say a website discharged in the first position, the website that still can let you sometimes becomes home page to stand to depilate even.

最近，百度对serp的排列更是变幻莫测，不要说网站的默认首页是否排在第一个位置，有时还能让你的网站成为首页站甚至拔毛。

The permutation is even if the number of inversions it contains is even.

如果一个排列中含有的反序的个数是偶数，则称它为偶排列。

An almost perfect nonlinear exponential permutation with high algebric degree is proposed, with some discussion on how to select the parameters of such permutation. The experimental result shows us a conjecture that there exists no such permutation over even dimensional space.

作者所取得的主要研究结果如下：(1)讨论了分组密码的条件攻击和技术攻击方法；全面总结了分组密码算法设计应当遵循的七项准则；概括了分组密码的四种强化技术；设计了一种新的三重加密方案NTE。

We provide a substitution box, exponential permutation which has much measurable security, and give a enumerating result and a fast algorithm of calculating such permutation. An almost perfect nonlinear exponential permutation with high algebric degree is proposed. with some discussion on how to select the parameters of such permutation. The experimental result shows us a conjecture that there exists no such permutation over even dimensional space. As a way of generating substitution boxes, we briefly point out the cryptographic weakness of the exponential functions derived from such permutation. We also present two new cryptographic indexes, fixed point and cyclic structure, on which we investigate the performance of such permutation. Finally, we give a viewpoint about the application of correlation immune functions in designing substitution boxes.

提供了一种可度量安全强度的代换盒－幂置换；详细阐述了幂置换的实现和计数问题；给出了一种计算幂置换的快速算法；从几乎完善非线性幂置换角度讨论了幂置换参数的选取，并提出了一种高次几乎完善非线性置换；通过试验给出了关于偶数维空间上几乎完善非线性幂置换的一个猜想；简要给出了由幂置换派生出的幂函数的密码局限性；针对幂置换，提出了两个密码安全指标：不动点和循环结构；证明了幂置换在这两个指标下的密码性能；简要讨论了相关免疫函数与代换盒设计的关系。

Positive association were still remained for two locus that MNAT1-rs973063 and PCNA-rs25406 and lung cancer risk even after 1000 times permutation test.During the stratified analysis,we revealed that that several genes in the NER pathway could interact with age,gender,family cancer history and smoking status.

在进行了多重校正后，有两个位点仍显示出关联显著性：MNAT1-rs973063(p=0.02)，PCNA-rs25406(p=0.03)；在随后进行的分层分析中，我们发现NER通路多个基因分别和年龄、性别、肿瘤家族史以及吸烟状况之间存在互作，提示该通路基因位点可能主要是通过和环境交互作用产生效应；我们还进行了单倍型的分析，结果发现PCNA和RPA1两个基因上的单倍型和肺癌易感性相关。

If we allow these 10105 molecules to randomly permutate, the rate of permutation is ten thousand (104) times per second. If the age of the universe was thirty billion years (1018 seconds), then from the beginning of the universe until now, the total permutations were 10127 times (10105x1018x104), which is not even enough time to develop one correct nucleotide sequence for one molecule of DNA.

如果让这10105个分子随机组合，令组合的速率为每秒一万次（104），假设宇宙的年龄为三百亿年（1018秒），那么，从宇宙形成到现在，一共可以产生的组合方式是10127次（10105x1018x104），还不足以产生一个有正确核亘酸排列组合序列的DNA分子2！
