A parallel split iteration algorithm for MIMD distributivity memory cluster on solving linear coefficient matrices is established in chapter three. Convergence is proved when the coefficient matrix is Hermite positive definite matrix or M-matrix. Discussing convergence range of parameter T . In the end, examples have been implemented on HPrx2600 cluster, and the data verify that the algorithm has favorable astringency and parallelism.

研究了一种适合于MIMD分布式存储并行机的交替方向法，理论上证明了在系数矩阵为Hermite正定矩阵和M-矩阵时算法的收敛性，讨论了参数τ的收敛范围，最后在HPrx2600集群上进行数值试验，结果表明此算法有良好的收敛性与并行性。

First, this study will use the questionnaire to explore all kinds of consumers' online shopping motivation, and then emend the questionnaire and form the ultimate one for the second process. Second, we will simulate a shopping site to get clickstream data, participants need to complete the ultimate questionnaire at the same time. We will analyse the integrated data from two measures, cluster analysis separately, and explore the correspondence between the two cluster methods.

研究分两个阶段：首先通过问卷调查的方法探测消费者的网上购物动机，并修订问卷；然后通过实验室模拟合问卷调查同时进行的方法获取网上购物动机和点击流信息，分别分类网上消费者，并探讨两种方法的对应关系。

The paper induces and analyzes research method of the tooth, including Method line of the tooth theory,Envlopment theory, Camus theory, Circling cluster theory and so on.Based on the past theories,the new measure to deduce the chain wheel tooth equation of roller chain at high speed,Circling cluster and envlopment theory,is proposed by analyzing basic concept of equidistant curve and Willis theory.Following the presentation of drawing lessons from traditional roller chainof the change of stanza line distance. A new type of roller chain at high speed is given in the paper.The paper studies deeply structural characteristics, the change of stanza line distance,separation between plank and bore and so on.According to design requst of roller chain at high speed and the study ofH_y--V_0 tooth chain,the impossibility that Quasi-conjugage engagement theory isrealized by the engagement of roller chain at high speed from the aspect of theory is decribed.

作者综述了高速滚子链国内外研究现状，并进行了以下研究工作：归纳分析了齿形法线法理论、包络法理论、卡姆士定理、圆族法理论等齿形研究方法，在此基础上，结合齿形啮合基本定律，分析了等距曲线的基本概念，提出了一种推导高速滚子链链轮齿廓方程的新方法—圆族包络法；在借鉴普通变节距滚子链的基础上，本文提出了一种新型的高速滚子链链条，深入研究了高速滚子链链条结构特性及其变节距、板孔中心分离等特性。

在上面的分析研究的基础上，根据集群服务器的设计原则和目标，设计了一个高效、灵活、可扩展的集群监控系统方案，可以最大程度的屏蔽集群服务器的单点失效，具有易于扩展的特点。

These clusters in the file allocation table in FAT cluster做上bad marks, so that it will not be covered by the permanent presence in the disk (the disk has been used in the cluster must be FAT file allocation table上簇do the tags, otherwise they will be other documents were covered by the use of).

这些簇在文件分配表FAT中做上坏簇的标记，使其不被覆盖而永久地驻留在磁盘中（磁盘已使用的簇必须在文件分配表FAT中做上簇的标记，否则会因其它文件的使用而被覆盖）。

The self-organization evolving mechanism of cluster sustainable growth are analysed and discussed , and the article think that the opening and unbalance is the precondition , fluctuating is the inducement , furcation and environment selection is the path , competition and cooperation is the power about cluster sustainable growth.

探讨了产业集群持续成长的自组织演化机理，并认为集群的开放性与非平衡是集群持续成长的前提；涨落是集群持续成长的诱因；分叉与环境选择是集群持续成长的路径；竞争与协同是集群持续成长的动力。

Giberrellic acid treatment is not recommended, but well-timed cluster thinning and cane girdling can increase berry size and improve cluster compactness.

Giberrellic酸处理，不建议，但适时集群细化和甘蔗环剥可提高果实的大小和提高集群紧。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
