ESTs of chickpea (Cicer arietinum L.) were downloaded from the database of NCBI and some redundant or low quality sequences were removed. Finally, 11224 non-redundant ESTs with total length of 6198092bp were obtained. SSRIT (Simple sequence repeat identification tool), a web tool for SSR hunting, was used to analyze the sequences.

And, we selected some representative species of Collembola and representative groups of Protura, Diplura, Insecta and Arustacean to sequence and analyze their 18S rRNA completely gene sequences, 28S rRNA D6-D7 domain and nearly completely gene sequences to make the studies about the phylogeny relationships of the main families and orders of Collembola, discuss the questions such as the reliability about the new four orders system to Collembola, the monophyletic and ordinal phylogenetic relationships of them and the situation of the special groups, the phylogenetic relationships about Collembola with other groups and the evolution of Hexapod.

同时选取弹尾纲的代表种类和原尾纲、双尾纲、昆虫纲、甲壳动物等节肢动物部分类群，进行了18S rRNA基因全序列和28S rRNA基因D6-D7区以及近全长序列的测定、分析，对弹尾纲重要科属的亲缘关系、进化地位进行分子系统学研究，讨论弹尾纲最新分类系统中四目的确定性、各目单系性、四目的系统关系、特殊类群的分类地位，以及弹尾纲和其它类群之间亲缘关系、六足动物进化等问题。

The results of the analysis to complete 18S rDNA and partial 28S rDNA D 6-7 domain sequences of 30 collembolan species supported the monophyly of Poduromorpha and Symphypleona, Entomobryoidea is not a monophyly, familia Neelidae should be separated from Symphypleona. The situation about the superfamilia of Tomoceroidea and the familia Neelidae need further studies. The results of the further analysis to complete 18S rDNA and nearlly completely 28S sequences of 4 Protura, 6Collembola, 5 Diplura, 5 Insecta, 10 Crustacean, using 1 Myriapoda and 1 Chelicerata as outgroups indicated that Protura, Collembola and Diplura are monophy, respectively, Protura and Diplura have the nearest realationship, they make sister groups with Collembola and all of them assemble with Insecta to make a monophy cluster of Hexapod; The results support the monophy of Pancrusracea, Crustacean is not a monophy cluster and the realationships between them with Hexapod need further reseachers.

对我国的14科27属30种跳虫的18S rDNA全序列和28S rDNA部分序列(D6-D7)的基因信息数据进行分析，结果支持原目、愈腹目的单系性，长角目不形成单系群，支持短角科从愈腹目中分出，但鳞总科和短角目的分类地位有待于深入分析探讨；进一步比对4种原尾虫、6种跳虫、5种双尾虫、5种昆虫和10种甲壳动物的18S rDNA全序列和28S rDNA全序列，以1种多足动物和1种螯肢动物为外群，进行系统关系分析，结果显示：原尾纲、弹尾纲、双尾纲分别为单系群，原尾纲和双尾纲优先聚为一支，然后和弹尾纲构成姐妹群，以上三类又和昆虫聚为一支，支持六足动物的单系性，支持泛甲壳动物，但甲壳动物并未形成单系，其各类群和六足动物之间的亲缘关系尚须进一步确定。3。

v+\$oXb；L^7h_0 目的：基于mc法生成符合预期概率分布的随机序列，以便应用在以后的仿真系统中。方法：应用线性同余法在visual studio环境中建立随机模型模拟随机序列生成。并采用χ2拟合优度检验法和自相关检验法检验生成的随机序列的均匀性、独立性。

In this paper, for a kind of generalized cyclotomic binary sequences with prime period N = 6 f+1, we computer their linear complexity. Specially, any one of the binary sequences has optimum balance among 0's and 1's.

本文中，我们构造了一类以奇素数N = 6 f+1为周期的分圆二元序列，证明了这类序列具有&好&的线性复杂度，适合于实际应用。

Methods:MRI findings of pancreatic carcinoma in 109 cases were analyzed retrospectively. All the cases were confirmed by operation, pathology and clinical practice. Conventional pancreatic sequences ( FLASH 2d T1WI, FLASH 3d T1WI, Declivate transection FS-T1WI, TSE-T2WI), MR cholangiopancreatography and dynamic contrast of Gd-DTPA sequences were used to find pancreatic lumps, adjacent infiltrated blood vessels and small pancreatic carcinoma.

经手术病理和临床证实的胰腺癌109例，经常规胰腺扫描序列（FLASH 2d和3d T1WI、倾斜横断面FS-T1WI、TSE-T2WI）、MRCP、Gd-DTPA动态增强扫描对胰腺癌、胰胆管扩张、周围血管侵犯及小胰腺癌诊断价值。

It is observed that the strong correlations in the coding regions may be blocked by the third base of codons,and the proper masking can extract the correlations.Distribution of dimeric tandem repeats of unmasked sequences is also compared with that of masked sequences.

结果表明构建得到的网络同时满足小世界网络和无尺度网络的特征，证明DNA序列不全是随机的序列，而是有随机扰动的确定结构的序列，特别是编码区。

The results were summarized as follows:1 Four cpDNA trnL-F, matK, rbcL, and atpB sequences analysis The chloroplast trnL-F, matK, rbcL, and atpB sequences from 31 species representing nearly all genera of Fagales (sensu APG, 2003) were used to reconstruct the phylogeny of the order.
