For a monotone twist map the well-known Birkhoff fixed point theoremsays that the circles with rational rotation number will break up whence a finitenumber of pairs of periodic points arise,half of which are elliptic and the othershyperbolic.Moreover,around each elliptic periodic point a few of new invariantcurves will appear and make a picture of phase space with a self-similar structure.Again one may ask is there a similar picture for higher dimensional Hamiltoniansystems?

对于单调扭转映射，著名的Birkhoff不动点定理指出，在通有情况下旋转数为有理数的不变曲线一般会破裂，在原来的不变曲线附近会产生有限多对周期点，其中一半是双曲的，一半是椭圆的，而在椭圆型周期点的周围又会产生一圈圈的不变曲线，使得椭圆周期点附近的动力学行为和整个相空间的动力学行为十分相象，换句话说，整个相空间具有无限嵌套的自相似结构，自然又产生了一个问题：对于自由度数目大于2的高维哈密顿系统，其相空间是否有类似的图象？

The action of page headline is self-evident, the rank that searching engine gave caption very great weight in the mechanism, look in me a successful caption should have these a few kinds of features: A, true the clou that mirrorred page article, caption and content write a law abhorrently is wrong apparently, it can let you lose the faith that searchs engine, also can let more caller prediction of a person's luck in a given year drop likewise. On the B, foundation in A, beautiful idea designs a more absorbing caption, a headline that contains window often searchs the webpage before the result to have taller hit in you than the platoon, as this hit rise, your rank also can be alled alone by search engine place takes seriously slowly, this kind of phenomenon once was in the article of President SEO (the imitate of the soft costal region of Baidu and Baidu place ignore is searched) in had mentioned. C, reasonable keyword density, avoid by all means does not pile up again in caption keyword, this kind of method already too pediatric.

页面标题的作用不言而喻，在搜索引擎的排名机制中给予了标题很大的权重，在我看来一个成功的标题应该具有这几种特征：A、真实反映了页面文章的中心思想，标题和内容不一致的写法显然是错误的，它会让你失去搜索引擎的信任，同样也会让更多的访客流失掉。B、在A的基础上，花心思设计一个更加吸引人的标题，一个含有亮点的标题往往比排在你搜索结果前面的网页有更高的点击率，随着这个点击率的提高，你的排名也会慢慢被搜索引擎所重视，这种现象曾经在SEO校长的文章(百度的软肋与百度所漠视的模拟搜索)中提到过。C、合理的关键词密度，切忌在标题中不要再堆积关键词了，这种手段已经太小儿科了。

Alternate connective has a few kinds of cases, I say to basically leave two kinds of commonly used way here: Home page is specification of station of A B C falls: If A C station is two my different sites, b station is the station of the other side, I and the other side change home page connective moment, I use the connection that B of the other side of the put away on A station stands,(This join also is one changes, because a lot of person misunderstood across,join is not one changes,) it is B of the other side next the link that needs to put my C to stand only on the station went, need not go putting the join that my A stands, also be one changes a join, this is the resource station that we provide many bits just.

交叉连接的有几种情况，这里我说下主要下常用的两种方式：首页是 A B C 站说明下：如果 A C 站是我的两个不同的站点，B站是对方的站，首页我和对方换连接的时候，我用A站上放好对方B站的连接，(这个连接也是一个换一个的，因为好多人都误会了交叉连接不是一个换一个，)然后是对方B站上只需要放我C站的连接就行了，不用去放我A站的连接了，也是一个换一个连接，这个是我们提供的资源站多点而已。

经1.5×10~2g/L地塞米松处理后，细胞表面微绒毛和丝状伪足显著减少或消失，出现皱褶状和小泡状结构；细胞核形规则，核质比值减小，异染色质团块减少，核仁数目减少、结构致密；细胞质中粗糙型内质网、高尔基体、线粒体数量增多，形态结构典型，游离核糖体减少，这些变化说明地塞米松改变了MGc80-3细胞的超微结构特征，具有明显的诱导分化作用。

After amplying a 2.2kb fragment form the PPV-SC1 RF-DNA,we clone the fragment into pMD 18-T,named pTNSl.The whole sequence which is 1989 bp long was determined by sequencing, including the complete ORF of PPV-SC1 NS1 which encoding 662 amino acids.Alignment of pairs of sequence indicates that there are 98% and 99% similary with other porcine parvovirus strains Kresse and NADL-2, respectively. Multiple sequence alignment discloses that there are a few difference between ppv-scl nsl gene and other ppv nsl gene: A-G at 39nt,T-C at 153nt,A-G at 175nt, A-C at 1117nt, A-C at 1535nt .Alternative codon in ppv-scl nsl have distinctly different frequentfy by codonbias analysis at EMBOSS(http://genopole.toulouse.inra.fr/bioinfo/emboss). Thereis not distinct hydrophobicity and transmenbrane helices in ppv-scl nsl protein. Struction domain anslysis of PPV-SC1 NS1 protein indicate that there are a ATP/GTP-binding site motif A at 398-405,16 Protein kinase C phosphorylation site,21 Casein kinase II phosphorylation site,and 3 cAMP/cGMP-dependent protein kinase phosphorylation site.At the same time ,there is a same motif between ppv-scl nsl and Poxvirus D5 protein-like which may share in the same fuction which is necessary during virion duplication.

将PPV-SC1 NS1序列与其他PPV NS1基因进行多序列比对，结果显示，PPV-SC1 NS1与其他的PPV NS1的同源性较高，仅存在个别的差异，分别是第39位A→G，第153位T→C，第175位A→G，第1117位A→C，第1535位A→C；同源搜索比较表明，PPV-SC1与PPV NS1同源性可达98％、99％，与其他的细小病毒NS1基因也存在很大的保守性；密码子偏向性分析结果表明PPV-SC1 NS1基因在同一氨基酸的不同密码子的选择上存在一定的偏向性；PPV-SC1 NS1蛋白总体上说具有亲水性不存在明显的疏水性区段，用swiss TMPRED软件预测PPV-SC1 NS1的跨膜区，返回的结果并没有得到有显著意义的跨膜区的存在；根据基于motif数据库的结构域预测，PPV-SC1 NS1的第393-415位氨基酸残基存在潜在的ATP／GTP结合位点，该蛋白还存在16个蛋白激酶C磷酸化位点，21个酪蛋白激酶2磷酸化位点，3个cAMP-／cGMP依赖蛋白激酶磷酸化位点，PPV-SC1 NS1蛋白与POX_D5(痘病毒D5蛋白)具有一致的保守结构域，推测NS1可能与POX_D5有类似的功能。
