入侵

In order to improve resistive capability of computer and network system,based on Multi-agent,a distributed network intrusion detection model and a distributed network intrusion detection system are presented.

针对当前形势，为了提高计算机及网络系统的防御能力，提出了一种基于多主体的分布式网络入侵检测模型，研究了基于多主体的分布式网络入侵检测系统。

With the parameters from published literature and experiments, we conducted forward analysis to compare soil organic carbon, carbon sequestration rate and soil total nitrogen dynamics of four different ecosystem types bare ground, Scirpus mariqueter, Phragmites australis, S.

通过构建九段沙生态系统碳氮模型并结合实测数据比较了互花米草入侵后生态系统土壤有机碳储量、碳封存速率和土壤总氮与其在土著占优势的3类生态系统（裸地、海三棱藨草、芦苇）中的差异，结果表明互花米草入侵的生态系统，其土壤有机碳储量高于裸地和海三棱藨草生态系统，却低于芦苇生态系统。

In addition,exotic C4 plant Spartina alterniflora is rapidly invading the salt marshes in the Yangtze River estuary,and displacing the native C3 vascular plants Phragmites australis and Scirpus mariqueter.It is no clear whether the C4 vascular plant invasion has serious impact on food web structure and trophic function of the salt marshes of the Yangtze River estuary.

另外，外来种互花米草正在快速入侵长江口盐沼湿地，这种C_4维管植物入侵将对盐沼湿地食物网及其营养功能会产生什么样的影响也是一个值得探讨的问题。

Round-the-world times is stationed in American special correpondent to be in charge of Liang Xu of reporter of Ke Jiang, round-the-world times to report from June 19, hype of media of American much home is so called " Chinese computer hacker inbreaks American assemblyman computer, touch American sensitive data " hind, beautiful assemblyman Fulanke Wolfe recently again to Chinese rise in revolt, say " inbreak number " far more than the imagination wants mediumly, go want far, and the Chinese already got everything.

环球时报驻美国特派记者管克江、环球时报记者梁旭报道自6月19日，美国多家媒体炒作所谓的&中国电脑黑客入侵美国议员电脑、触及美国敏感资料&后，美议员福兰克·沃尔夫近日再次向中国发难，称&遭入侵人数&远比想象中的要多，走的要远，而且&中国人已得到一切。&

It allures attacker by some obvious security holes, at the same time, monitors the hackers behavior and records all the information for further analysis.

它通过构造一个有着明显安全漏洞的系统来引诱入侵者对其进行攻击，并在攻击的过程中对入侵者的入侵动机、入侵手段、使用工具等信息进行详细地记录。

Particularly, intrusion detection system has been presented to detect attacks that bypassed the prevention methods.

入侵检测系统能够用于检测各种形式的入侵行为，是安全防御体系的一个重要组成部分。

Sequence analysis to system call sequences is an important method in intrusion detection,for most of the system intrusions are conduced by illegimate or irregular system calls to operation system.

大多数的入侵行为是由于一系列操作系统内部的非法或异常调用引起的，因此对系统调用序列进行分析是入侵检测的一个重要方法。

And then,at the foundation of the practice running result, we analyzed and summarized the advantage and weakness of the system based on immunity. On the other hand,through analyzing the existence questions of current intrusion response system,this paper proposes a intrusion response model based on workflows,scheduling problem and J2EE framework. This model filtrates alarm before response, at the same time,it can also predict the coming attacks on-line and make the corresponding response measures .

另一方面，通过分析当前入侵响应系统存在的问题，提出了一种基于工作流和作业调度的J2EE框架构建的入侵响应模型，该模型先对所有报警事件进行过滤然后予以响应，并在响应当前报警事件的同时根据报警信息之间的关系，对进一步可能发生的攻击做出在线的预警并产生相应的响应措施。

Nowadays alien species invasion has become one of key factors of imperiling biology multiplicity .

外来物种入侵已成为威胁我国生物多样性的主要原因之一，防范外来物种入侵的法律研究已显得相当急迫。

Along with the influence of world economy,trade and communications development with high speed, alien species invading sharply day by day,has become one of key factor of imperilling biological diversity and ecological environment of our country and has caused great losses of ecology and ceonomy.legislation of alien invading species management should abide risk precautionary principle.

随着世界经济、贸易和交通高度发达的影响，外来物种入侵活动日益加剧，已经成为威胁我国生物多样性与生态环境的重要因素之一，对我国的一些地区造成了巨大的生态和经济损失。有关外来入侵物种管理的立法应贯彻风险预防原则。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
