集中于

We begin with an introduction of the research background, the difference between traditional network management and security-oriented network management, and the contributions of this paper. Then we present the structure and the principles of the SIMP: we put forward to a functional and hierarch model based on JMX specification and Struts technology And a JMX-based network management model.

本文首先介绍了课题的背景、网络安全管理相对于网络管理的特点和本文的研究内容，针对传统网络管理的不足，提出了安全集中管理系统的总体结构、组成及工作原理：安全集中管理平台的体系结构采用JMX技术作为系统的集成总线，将各管理功能模块作为JMX管理构件，实现了系统的组件化、模块化的开发；层次结构采用了基于Struts的MVC架构模式，底层数据库采用了对象关系映射技术，提高了系统的可维护性和可扩展性。

Although the producer services observationally concentrates in metropolitan areas, the correlative literatures especially the experiential researches are scarce because of being empty of applicable theory and effective analysis tools and methods.

生产性服务业在都市区呈现集中分布状态，由于缺少统一理论指导和有效的分析工具及方法，长期以来有关生产性服务业地理集中的文献相对较少，且多局限于描述性分析。

Based on an appropriate monitoring function, a switching scheme is proposed so that after a finite number of switching, the tracking error can converge exponentially to zero if the plant relative degree is one, or a residual set whose radius is proportional to some design parameters if the plant relative degree is greater than one.

在监控函数的监测下，相关的控制信号经至多有限次切换后将停止切换，系统跟踪误差指数收敛于零(若被控系统相对阶为1)，或收敛于一个正比于设计参数的残集中(若被控系统相对阶大于1)。

The union of any two sets consists of those elements that are in one or the other or in both given sets; the intersection of two sets consists of those elements that are in both given sets.

任何两个集合的并集包含了出现于这两个子集中某一个集合或同时出现于这两个集合中的所有元素；两个集合的交集包含了同时出现于这两个集合中的元素。

ERK1/2 immunohistochemistry positive staining coloration in cornu dorsale medullae spinalis of rats was Buffy color.Positive cells distributed in gray nucleus that nerve cell concentrated,and deep staining region localized at the nucelus of neurocyte.

针刺前后脊髓未见明显形态学改变。2、光镜下观察，大鼠脊髓背角ERK1/2免疫组化反应显色呈棕黄色，阳性细胞分布于脊髓灰质神经元集中的部位，针刺后深染部位向胞核集中。

Because the photospheric temperature of carbon stars are less than 3000K and the temperature of rich-dust envelope formed by the mass loss is lower, and therefore most of the energy from carbon stars are radiated between 1 to 60um range, in which the vibrational and ro-vibrational bands of many molecules also lies, the study of infrared spectra in this wavelength range is very important to reveal chemical compositions, dust formation process, the atmospheric structure and evolutionary status of stars.

碳星光球的有效温度不超过3000K，同时较大的质量损失率形成了富碳的尘埃壳层，以致于它的辐射能量主要集中在1—60μm的红外波段上，并且许多分子的转动振动能谱也集中在红外，因此在红外波段的研究对揭示碳星化学成份及其分布、尘埃形成过程、恒星大气结构和演化状态都有十分重要的意义。

The major dominant species of predatory enemies were Erigonidium graminicola and Theridion octomaculatum and their individuals were 81.4 percent of the total predatory enemy individuals of the community.1.2 Spatial patterns and their dynamics of major dominant predatory enemies ofarthropod communityThe research results showed that Pieris rapae distributed mainly on heart leaves and back of inner leaves of cabbage plants, Plutella xylostella distributed mainly on the back of cabbage leaves and Lipaphis erysimi distributed widely in cabbage plants. Among the major dominant species of predatory enemies, Sitticus sinensis distributed mainly on the front of leaves of cabbage plants in spring cabbage fields, and Misumenopos tricuspidata and Propylaea japonica distributed widely in cabbage plants.

在捕食性天敌中蜘蛛10种，捕食性昆虫3种，主要优势种为草间小黑蛛、八斑球腹蛛，其数量占捕食性天敌总数量的81.4%。1.2节肢动物群落主要优势种的空间格局及其动态研究结果表明，害虫优势种菜青虫主要分布于甘蓝心叶和甘蓝叶反面，小菜蛾主要集中分布在甘蓝叶的反面，而菜蚜在甘蓝植株内的分布较广；春甘蓝田捕食性天敌优势种中华跃蛛在外层叶正面分布较集中，三突花蛛与瓢虫类在甘蓝植株内的分布较广。

How to centrally control these ECUs in an effective, orderly, safe and convenient way and how to synthetically use their information have already become theoretical and applied problems that must be solved urgently in the course of applying electronic technologies to cars and development of the car's technologi...

本文以多个项目为支撑，特别是在法国洛林国家信息及其应用研究实验室(LORIA：Laboratoire Lorrain de Recherche en Informatique et ses Applications)实验室的技术支持下，针对轿车电子控制系统存在的问题，立足于提高轿车整体性能，基于将轿车中各种独立的功能系统关联信息集中传递和控制的思路，采用当前先进的车载网络，研究轿车信息集中控制系统(CICCS：Car Information Central Control System)及其主要关键技术。

I thinks, should be similar to to coming to China one year game industry always reviews of state of affairs of development of network game estate especially, be in abroad, such similar exhibiting meeting, join the metropolis that postpone business to bring them individually commonly newest the modernest play and a series of modern notional sex technologies, and the CJ that sees us, all focuses are in centrally another " Ding Beili " on the body, might as well the news that reviews the concerned CJ last year, besides manufacturer news (of course the centers the look before he exhibits a stage belle of large also space gets on manufacturer news personally), report press from rich guest, outside notting have bosom of bikini belle, belle is compared greatly go all out, each exhibit stage belle big round of drinks of cool and refreshing degree reads an and his like, now year?

愚以为，应该类似于对一年来中国游戏产业非凡是网络游戏产业发展情况的一个总回顾，在国外，类似这样的展会，一般各个参展商都会带来他们最新最时髦的游戏以及一系列时髦的概念性技术，而看看我们的CJ，所有的焦点都集中在一个又一个&丁贝莉&身上，不妨回顾一下去年的有关CJ的新闻，除了厂商新闻外（当然厂商新闻也大篇幅的把目光集中在自己展台前的美女身上），从博客报道到新闻报道，无外乎比基尼美女、美女胸部大比拼，各展台美女清凉程度大巡阅之流，而今年呢？

But Mr. Bush rejected the idea of mass deportations."It is neither wise nor realistic to round up millions of people, many with deep roots in the United States, and send them across the border," he said.

但布什先生拒绝了集中遣送的建议，&集中数以百万记的人并遣送他们穿越边境既不明智也不现实，他们很多已经深深扎根于美国，&他说。
