The authors investigated the singular limits of stiff relaxation and dominant diffusion for general 2×2nonlinear systems of balance laws, that is,τ=o,ε→ 0, the relaxation time τtends to zero faster than the diffusion parameter ε. If there exists a priori L∞ bound that is uniformly with respect to ε for the solutionsof a system, then the solution sequence converges to the corresponding equilibrium solution of the system.

研究一般扩散占优的2×2双曲平衡律系统奇异松弛极限，用补偿紧性方法，在松弛时间τ比扩散系数ε趋于零快时，即τ=o，ε→ 0时，得到其解的整体存在性一般框架：如果上述系统的解存在对ε一致的先验L∞估计，则其解序列收敛于上述系统的对应平衡状态解。

But it is obviously under 97.0% with other groups. With further comparing the rps3 gene of ribosomal protein gene for the CWB-YN strain,the results show that these strains shared highest homology (98.1% and 100%)with Aster yellows and Periwinkle yellows.

First, based on all that have been mentioned above, the geometric constant D, which was introduced to characterize the quantitative difference between Birkhoff orthogonality and isosceles orthogonality, is studied further. Moreover, attainability as well as continuity and monotony of D in two-dimensional sequence spaces are presented.

In chapter three, we first introduced the Marcinkiewicz large law and Bernstein inequality, then we gave the sufficent conditions for weak consistency, strong consistency and uniformly strong consistency of NN-estimator for NQD samples.

第三章介绍了两两NQD混合序列的概念和Marcinkiewicz弱大数定律及推广的Brenstein不等式，讨论了在NQD混合情形下最近邻密度估计的强、弱相合性及一致强相合性。

Based on the conservation of miRNAs sequence, we compared the known miRNAs among five mam-mals, i.e., human, mouse, cattle, pig and dog with the sequence of sheep genome that is highly homologous to goat genome, published on the NCBI, and 11 candidate miRNAs were eventually obtained. RT-PCR analysis showed the expression of the 11 miRNAs in brain and 5 in liver, indicating that they might be novel miRNAs. The methodology provides an alternative approach to the exploration of new miRNAs in goat.

根据miRNA分子具有一定的保守性，文章将人、小鼠、牛、猪和狗5种哺乳动物已知的miRNA分子与NCBI公布的与山羊具有极高同源性的绵羊基因组序列对比，获得11条miRNA候选分子，然后通过逆转录聚合酶链反应验证，发现在山羊脑组织中这11条分子均有表达，肝脏组织中有5条分子表达，初步确定为山羊新的miRNA分子，为寻找山羊miRNA提供了新的思路。

After analyzing the shortages of the existing algorithms for frequent pattern clustering,proposes an algorithm for creating compressed partial order based on pattern clustering function.Experiment result shows the compression arithmetic has higher proficiency and qualify,also can obtain much less number and much more information pattern.Thereby can find out more interesting of visited frequent sequential than the normal algorithm.

分析了现有频繁模式聚类算法的不足，提出了在模式聚类函数的基础上生成一个压缩的偏序的算法，实验结果显示该算法可以对频繁序列模式进行高效、高质量的压缩，可以得到数量更少、信息量更大的模式，从而提高发现的频繁访问序列的兴趣性。

The apxⅢA gene of Actinobacillus pleuropneumonie was amplified by PCR. The amplified DNA fragment 3 466bp was cloned into pMD18-T. After R.E. analysis and sequencing, the apxⅢA gene in pMD18-T was ligated into pBluescripⅡSK, the recombinant expression plasmid pET-28b/apxⅢA was constructed and analysed with R.E., the protein of apxⅢA gene expressed in E.coli BL21 was detected by Western blotting.

因胸膜肺炎放线杆菌的致病性主要是由毒素决定的，故参照猪胸膜肺炎放线杆血清2型菌株的序列(GenBankL1 2 1 4 5)设计了一对特异性引物，用PCR的方法扩增apxⅢA基因并得到了长 3 466bp的片段，然后将其克隆到pMD 1 8T中，经酶切鉴定和序列分析表明克隆是成功的；再将apxⅢA插入到原核表达载体pET 2 8b后，转化BL2 1 (DE3)，在IPTG诱导下获得高效表达，经Westernblotting检测证实表达产物有活性。
