非重要的

The firms located in industrial cluster are important ties that linked the local industrial cluster and the global production network. They are as well as the micro-dynamics for the clusters' upgrading and evolution in the context of economic globalization. The existing researches on industrial cluster almost focus on the cluster's competitive advantages as a whole unit, which has supposed the firms in clusters are homogeneous and opportunity equipotent that can get extra advantages compared to the un-clustered firms.

集群企业正成为联系地方产业集群与全球生产网络的重要纽带，是经济全球化背景下产业集群升级和演进的微观动力；从已有的集群理论研究成果来看，目前的研究主要集中于集群整体层面，研究的焦点是对集群整体的竞争优势进行探讨，集群企业被假定为是具有同质性和机会均等性的，相对于非集群企业可以获得一种"非对称"的特殊竞争优势。

In chapter three, in order to distinct N 0?matrices that defined by deferent references, we will use the following notions. A matrix is called N_0~2-matrix if the matrix is nonpositive and its all-principal minors are nonpositive.

不可约矩阵Perron余的Perron向量同原矩阵Perron向量有着继承性，另外非负矩阵的Perron余也可用于Perron根的估计，因此非负矩阵的Perron余的研究有着重要的理论价值。

With the development of the oilfield, deviated wells, sidetracking wells and horizontal wells have more and more important function,whereas the particularity of casing programme limited the landing depth of sucker rod pump ,and affected the producibility of oil well seriously.

随着油田的开发，斜井、侧钻井、水平井等非直井在油田开发中起到越来越重要的作用，但由于井身结构的特殊性，限制了有杆泵的下入深度，严重影响了油井的生产能力，同时抽油井杆管偏磨，已成为非直井降低产量，增加作业成本、增加杆管成本的主要矛盾。

This paper has studied the physiological and biochemical changes during the period of forming strong buds of tree peony, and expect to provide academic basis for extending its view value and economic benefit . The main results are as the following:1 Under the field condition, Characteristics of photosynthesis of tree peony are very regular. From before blooming to the prophase of abducting buds that after blooming ,that is April,May and June,the net photosynthetic rate of tree peony is higher than the other period .It indicates that this period is very important for accumulating photosynthetic products of tree peony . So, if we want to get quality flower of tree peony ,it is very important to strengthen the management of tree peony cultivation and to ensure provide the fertilizer and water.2 From the middle ten days of June, with the time elapsing and with the environment conditions worsening, the characteristics of photosynthesis of tree peony decline deeply. But it is different among different tree peony breeds. For example , cv. Wu Long Peng Sheng can also has higher net photosynthetic rate, it indicates that cv. Wu Long Peng Sheng is super than the other two tree peony breeds when adapting the environment conditions and cv. Wu Long Peng Sheng has wide prospect to extend .3 The main factors of effecting the characteristics of photosynthesis are stomatal factor and non-stomatal factor ,that is the ability of photosynthesis of leaf cells. Under the environment of high light intensity in midsummer, if overshadow tree peony properly, then it can slow the declining of chlorophyll content, and increase the net photosynthetic rate and benefit for the accumulating of photosynthetic products.4 The content of soluble sugar in the root of tree peony is the highest among different organs during the period of forming strong buds . According to analyse ,we believe that the soluble sugar will compose starch then, and provide the solid base of material for the growth and development next year. It provide us strong academic basis of adopting the method of cultivating root and protecting root under thefield environment conditions .In other words ,it will help to increase the health level of the whole plant of tree peony and will be beneficial to forming quality tree peony flower if we strengthen the management of root. 5 To tree peony, the endogenesis hormone is important for its growth and development .In the prophase ,that is about the blooming of tree peony and the mid-summer ,IAA and ZR contents are higher and GA content is lower and its changes are very little, and the content of ABA is decreasing . This indicates that IAA and ZR act the important promote function for growth and development of tree peony in this period, and the function of GA is not important. Bur in the period of anniversary senescence of tree peony , the content of IAA and ZR begin to decrease ,while the ABA content has a certain rebound .T

本研究对几个牡丹品种壮芽形成过程中的某些生理生化变化做了研究，以期了解牡丹生长发育过程中生理生化的变化规律，探讨大田栽培条件下提高牡丹花质量的栽培措施和管理技术，为提高牡丹的观赏价值和经济效益提供理论依据，结果如下：1 大田栽培条件下，牡丹光合特性在生长发育过程中表现出极强的规律性，牡丹各品种的光合速率从牡丹开花前，到牡丹花谢后的花芽诱导期前期（6月10日之前），也就是在4、5、6月份，各牡丹品种的净光合速率相对与其他时间都维持在比较高的水平，这说明，在这段时间，是牡丹光合产物积累的重要时期，因此，要保证得到高质量的牡丹花，在这段时间加强对牡丹的栽培管理，保证这个时期的肥水供应十分重要。2 从6月中旬后，随时间的推移，环境条件的恶化，牡丹的光合性能剧烈下降，但是不同牡丹品种间仍有差异，比如，乌龙捧盛仍可维持较高的光合水平，这说明了乌龙捧盛这个牡丹品种对于环境的适应性较之其他牡丹品种高，有着广泛的推广前景。3 影响牡丹光合性能的主要因子是气孔因素和非气孔因素即叶肉细胞的光合能力，在盛夏高温高光强的环境条件下，对牡丹进行适当遮荫，能缓解牡丹叶绿素水平的下降，适当提高Pn，有利于光合产物的积累。4 可溶性糖在牡丹各品种的壮芽形成过程中，根中可溶性糖的含量在牡丹各部位中始终维持最高水平，分析认为这些可溶性糖在根系中进一步合成淀粉等储藏性物质，为来年牡丹的生长提供雄厚的物质基础，这为我们在大田栽培条件下对牡丹采取养根护根的栽培措施提供了有力的理论依据，即在大田栽培条件下，加强对牡丹根系的管理，有助于提高牡丹整株的健壮程度，有益于形成高质量的牡丹花。5内源激素对牡丹的生长发育调节作用是十分明显的，在前期，即开花前后和盛夏，IAA和ZR含量维持在比较高的水平，GA含量低且变化不明显，ABA含量逐渐降低，说明了IAA和ZR对牡丹在这段时间内的生长发育起到重要的促进作用，GA的作用不是很明显，ABA可能在高温高光强下有明显的升高，也说明了ABA的确有一些促进作用，但是到了牡丹周年衰老期，IAA和ZR的含量开始下降，ABA含量却有了一定程度的反弹，说明了IAA和ZR的作用开始降低，ABA起到了促进衰老的作用

By the theory of dissipative structure, the questions appearing in the process constructing a harmonious society can be solved, including goodness and badness of equilibrium and non-equilibrium, merits and demerits of order and un-order, happiness and worriment of difference and contradiction, and right and wrong of static harmony and dynamic one.

运用该理论可以有效解析当代和谐社会构建过程中存在的几个重要问题"平衡"与"非平衡"的好与坏、"有序"与"无序"的优与劣、"差异"与"矛盾"的喜与忧、"静态和谐"与"动态和谐"的是与非。

OR＞1 indicates dangerous factor, OR＜1 protective factor, and OR=1 no significance. The results showed that if triglyceride and very low density lipoprotein cholesterol increased an average level of normal respectively, and there would be OR of TG 2.43 (P＜0.05) and OR of VLDL-C 6.09 (P＜0.05), the high levels of TG and VLDL-C were the factors of lithogenesis. High density lipoprotein cholesterols (HDL1-C, HDL2-C, HDL3-C), with OR less than one, were the factors of protecting against the formation of gallstone.

结果：甘油三酯和极低密度脂蛋白胆固醇每增加一个正常均值水平，OR值分别是2.43(P＜0.05)和6.09(P＜0.05)，是重要的致石因素指标；高密度脂蛋白胆固醇(HDL1-C、HDL2-C、HDL3-C)，OR值均低于1，是重要的防石因素指标；低密度脂蛋白胆固醇和总胆固醇的OR值均小于1，本研究结果提示其可能是一种代谢状态而非保护因素。

Elisabetta Bugianesi, MD, PhD, who was not involved in the study, agrees that nonalcoholic fatty liver disease in particular is an important clinical entity that can be difficult to identify."NAFLD constitutes a special challenge for physicians for several reasons: any distinction between nonprogressive and progressive disease is only based on liver histology, but NAFLD patients are generally asymptomatic invasive procedures are not easy to propose to accept," she told Medscape via email.

未参与此项研究的Elisabetta Bugianesi医师同意非酒精性脂肪肝病是重要的临床表徵，但是却不易鉴别诊断；她以电子邮件向Medscape表示，NAFLD对医师们构成一个特别的挑战，因为在非进行性和进行性的疾病之间的差别，仅可从肝脏组织判断，但是NAFLD病患一般是没有症状的，所以对於侵入式的诊断方式难以接受。

Therefore, with regards to the cases of the application to the streaming media on the demand of the real time quality and the contradiction of the inadequate bandwidth of the present Internet, the article analyzes the unbalance QoS controling strategies from the viewpoint of the predistribution of bandwidth, the streaming dispatching, the handling of the data losing, and the processing mistakes and so forth, taking advantages of the unbalance on the distriution importance of the streaming media data, to guarantee the real time of the important data.
