In chapter 2 of this dissertation, we give the mathematical definition of selfsimilarity, and describe some of its properties. How to justify a self-similar process and get its autocorrelation coefficient (or self-similar parameter) are also discussed.

由于对于非马氏过程的排队系统进行数学分析是十分困难的，因此，对自相似业务流特性及网络性能的研究，大多采用某种近似的数学求解，或直接进行计算机仿真，这就需要有快速、准确的自相似序列生成方法。

Internet personage tells a reporter, of skyline bleachery roll out, can call catchword at will in bleachery at will especially, catchword content will make a central point, and everybody wants to contend for the first, what will naturally cause integral is fast use up, so skyline should be met in debut later other the way that wins integral, fill value RMB to obtain integral for instance, in current SNS gain difficult situation falls, skyline of this game roll out, it is a very good attempt undoubtedly.

有互联网人士告诉记者，天涯晒场的推出，特别是可以随意在晒场里随意喊口号，口号内容将会成为一个焦点，而且大家都想争第一，势必会造成积分的快速消耗，所以天涯应该会在稍后开通其他获得积分的方式，比如充值人民币获得积分，在当前SNS盈利困难的情况下，天涯这个游戏的推出，无疑是个很好的尝试。

This paper,after reviewing endowment insurance,cooperation medical treatment,bottommost life security and immigrant worker's security,concludes the following problems in rural social security system of Heilongjiang: wide coverage of security with lower insurance payment;many problems existing in implementing new-type rural cooperation medical system and bottommost life security system;ever-increasing government's focus on immigrant worker's security.

黑龙江省是一个农业大省，在确保全国粮食供应方面做出了很大贡献。近年来，随着经济发展和社会进步，黑龙江省的农村社会保障制度建设也有了一定发展。但是，不可否认的事实是，黑龙江省农民的一些生产和生活仍然缺乏必要的保障，如农村养老保险问题、看病问医困难的问题等等。

When I look back, I always feel so proud and honor. The restoring of Yuan Ming Yuan has long way to go. The demolishment was done in 1860 by Anglo-French allied force. This destruction make lots of antique and information missed over world. We are lack of draw, information, technology.

圆明园复兴的千秋大业任重而道远。1860年英法联军带给它毁灭性的灾难，至今仍有大量的文物资料遗失国外，缺乏资料和图纸，缺乏资金和技术，在保护整修的过程中，遇到的困难是可想而知的。

The homology of the nucleotide sequences and genetic variation analysis of NDV strains suggested that mere were obvious divergence in gene lever among NDV vaccine strains and epizootic strains isolated from different areas and different ages.The divergence may have effect on amino acid and structure and function of protein in some extent and lead to difference of immunogenicity ,which was one of reason being difficult in preventing from ND.

通过对NDV F基因核苷酸序列同源性比较及遗传变异分析发现：我国不同年代、不同地区分离的NDV毒株与疫苗毒株之间在基因水平上存在较大差异，这种差异对氨基酸及蛋白质的结构和功能可能会有一定影响，而NDVF蛋白的差异同时也造成免疫原性的差异，这很可能是新城疫的免疫防治十分困难的原因之一。

ABSTRACT The technology of Computational Fluid Dynamics has been widely used in many aspects of the whole ship design process.

CFD在船舶设计中的应用研究是个既困难又复杂的问题，但由于它的成功应用会提高船舶设计的效率和能力，因此这是个很有价值的研究方向。

Howard: What do you recommend for someone who worked up a man-sized appetite from a morning of weight training and cardio funk? recommend:推荐 man-sized: adj.

As the inversion and compression attack includes the question relating to solving thepreimage from image of function, a subdivision algorithm for solving preimage of function withbounded derivative based on Lagrange mean value theorem is proposed firstly.

由于逆推压缩攻击方法涉及混沌映射的求逆，针对复杂混沌映射求逆困难的问题，运用拉格朗日中值定理，我们提出了求解导函数有界的函数原象的分割算法，给出了使分割算法计算复杂性上界达到最小的充分条件。

The split between the two groups can hardly be papered over.
