It is a difficult problem for a big prime integer, if we select a primitive root according to its definition the performance of the secret communication could be affected seriously since the operation cost is very high. So this paper presents and proves an algorithm for searching a primitive root with high efficiency and gives the design of flow and corresponded JAVA program.

第一步：随机选取大素数P和在GF上的本原根g，并将P和g作为公开信息；第二步：用户A想和用户B建立保密通信时，就要交换共享的密钥KAB，A随机选取整数XA(1≤XA≤P-1)，并且计算出YA=gXAmodP经共用信道传给B，将XA保密；第三步：用户B随机选取一整数XB(1≤XB≤P-1)，计算出YB=gXBmodp，也经共用

Results Same conservative sites and key catalytic sites existed among SjLDH and LDHs from other species. Similarity of SjLDH compared to CsLDH, TvLDH and HsLDH was 75%, 17%, 58%-60% respectively. Phylogenetic analysis demonstrated that the evolution relation between SjLDH and DmLDH was closer than the relation between SjLDH and CeLDH, the relationship between SjLDH and HsLDH-B,-C was closer than HsLDH-A. Three trans-membrane regions were found, the region of 98aa-106aa in three hydrophilia regions located outside of membrane was inferred as the major antigen epitope. This antigen epitope had significant difference with LDHs from protozoon （ Pf ., Tg ., Tv .） and had 1-3 amino acid residue difference with MmLDH, HsLDH-A,-B,-C, and was the same with CsLDH. One of the key catalytic residues and substrate binding loop were located in this region. Tertiary structure demonstrated that 98aa-106aa was on the surface of the protein and formed a substrate binding loop, other two key catalytic sites were at the position near the loop.

结果 SjLDH与其他物种的同源序列含相同的保守位点及催化活性位点，与华支睾吸虫LDH同源性最高为75％，与阴道毛滴虫LDH同源性最低为17%，与人LDH（HsLDH-A，-B，-C）的同源性为58%~60％； SjLDH与果蝇的进化距离较秀丽隐杆线虫为近，3种人LDH中与HsLDH-B、-C的进化距离较HsLDH-A为近；该蛋白具有3个跨膜区域，3个高亲水性区域，主要的线性表位98aa~106aa位于膜外，与原虫LDH相同区域差异显著，而与其他LDH有1~3个氨基酸的差异，关键催化位点之一及底物丙酮酸结合区域位于该区域，蛋白质同源模建分析表明该区域位于蛋白表面形成环状结构，3个关键催化位点位于该区域或在其附近。

In his excellent book The No A****** Rule (I'm omitting the title not from prudery but from fear of spam-blockers), and also on his blog, Work Matters, Bob Sutton has a quiz to help people recognize if they are a*******-- I was inspired to adapt that material for this quiz.

在Bob Sutton所著绝好的一本书"The No A****** Rule"（我省略了标题不是因为假正经，而是担心垃圾邮件拦截）中，以及在作者的博客Work Matter上，作者有一个小测验帮助人们发现自己是不是一个a*******。

Plaques of these virus strains were obviously different in size and shape. The plaques of A/Vietnam/1194/2004 (H5N1) were mainly large in size and round in shape, except for a few smaller plaques appearing punctiform in shape. While A/Beijing/01/03(H5N1) were dominated by plaques of moderate size, also mixed with a few punctiform plaques.

结果 野生的人源H5N1禽流感病毒株在空斑形成上都存在不同程度的不均一性，空斑大小、形状差异明显：A/Vietnam/1194/2004(H5N1)以大圆形斑为主，夹杂少量小点状斑。A/Beijing/01/03(H5N1)大多数为中等大小空斑，并有少数针尖状斑。

With the reduction of SOM content and the elevation of contamination concentration, the difference between PHE and PYE decreases gradually, while B［a］PYE exhibits a significant difference from them. This could be attributed to the high lipophilicity and large molecular size of B［a］PYE, which make the molecule of B［a］PYE to be more easier to be held in the nanopores of clay and the dense region of SOM.

不同多环芳烃SPMD辅助解吸率差别很大，随着土壤有机质含量的降低，以及污染物浓度的提高，菲和芘的解吸差异逐渐缩小，而苯并［a］芘与上述2种多环芳烃的差异很大，主要是由于苯并［a］芘具有高度亲脂性，并且分子较大，造成其容易滞留在粘土的微孔及有机质的致密结构中。

Somewhere up in the attic is a brown, medium-size Samsonite suitcase that was a Christmas present in 1981. It served me ably all during my years as a traveling college textbook salesman, spending more nights in La Quinta Motor Inns than I care to remember.The reason I bring up that hard-cased suitcase is that the same item appears in "The Pursuit of Happyness," which opened this past Friday. I'm sure the prop department found one on eBay or at a garage sale.

刚刚看完了《the pursuit of happiness 》心理真的是感慨万千，里面有的话特别好，小男孩在打篮球的时候，他爸爸说他小的时候，篮球打得很烂，然后说小男孩的水平也不可能很好，然后小男孩很气馁，他爸爸说：hey ，you have a dream ，and you should protect it.never let people tell you ，you cannot do anything，because they can not do it ，so they tell you cannot do it。

Cen A, also known as NGC 5128, is also unusual compared to an average elliptical galaxy because it contains a higher proportion of young blue stars and is a very strong source of radio emission. Evidence indicates that Cen A is likely the result of the collision of two normal galaxies.

又名为NGC 5128的半人马座A和寻常椭圆星系的其他差异有：较高比例的年轻蓝色恒星和会发出很强的电波辐射，这些证据指向半人马座A是二个正常星系互撞后的产物。

This invention is to provide a telephone exchange capable of operating any one of the juxtaposed and registered extension radiotelephones and wire telephones by only specifying one extension dial number. For this purpose, a wire port physical number is registered in association with a radio port physical number so that two normally separate extension wire telephone (006a, 006b, etc.) and radiotelephone (008a, 008b, etc.) can be handled as if they were a single-channel extension phone with a branch switch.

本发明是为了提供这样一种电话交换机：只需指定一个分机拨号号码，便可使用并置的和被注册的分机无线电话和分机有线电话中的任何一个，因此，有线端口的物理号码和无线端口的物理号码被联合注册，这样，两个在常规上是分离的分机有线电话（006a，006b……）和分机无线电话（008a，008b……）可以象具有一个分支切换a branch switch）的单通道分机电话一样来被处理。

On the other hand, rat primary mixed glia culture was employed to verify the effects of LPS, IFN-γ and Aβ42 oligomers on activating microglia. LPS, IFN-γ, Aβ42 oligomers plus IFN-γ, and Aβ42 oligomers alone effectively activated microglia by changing cell morphology from ramified to amoeboid.

另一方面，利用大鼠的初级胶细胞混合培养来证明LPS、IFN-γ和Aβ42 oligomers对於活化微小胶细胞的影响，我们发现LPS、IFN-γ、Aβ42 oligomers加上IFN-γ和Aβ42 oligomers单独处理皆可以将微小胶细胞的形态由分枝状变成阿米巴状。

Lee Chung-kwong, explained at the time of the original:"A-share market in the hope that the re-erection of a financing platform, but also for the future to pave the way for the development of Shanghai Electric; there is another factor to consider is that in the A shares To raise the yuan can be used directly in the domestic market."

李重光解释说，在原始时间："在希望重新建立一个融资平台，而且为今后的发展铺平了道路A股市场上海电气，还有另外一个需要考虑的因素是，在A股，筹集人民币可用于直接在国内市场。"

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
