Focused on " understanding media " , the article analyses in chapter i the key media theory of employing what could be of mcluhan in a thoughtful angle ， and advances the viewpoint of " human being - the extending of media ? " . in chapter ii 、 in the following third part ， the idea of " media ' s endding " is expounded and demonstrated ， which is composed of three parts ： extreme of speed ， content of the content ， and human being ' s last extending - the extending of central nerves 。 in the final part ， the general conclusion ? ? electronic media ' s influence on human behavior is given ， that is human are under universal narcissism and pacing to the bottom of it impelled by electronic speed . the article has five original points in it ： first of all , in virtue of " content theory " ， it analyzes the theory of " meida equals to information " by mcluhan from a scale theory stand . secondly , the tremendous power of electronic media is emphasized from an implosion view . in the third point , the article advanced originally that , after extension of central nerve system , human themsevels reverse to an extension of media and turns into a node of it ; at the same time , the article proposes that , all extensions before that of central nerve are " controllable extension " , however , it reverses to " uncontrollable extension " while extending ; then the authur put forward for the first time that , the concernful reason obsessing human is the failure of their in - body central nerve system " s jointing and controlling on out - body central nerve system naturally . 。 the fourth point is , the article demonstrates systematically the idea of " media ' s endding " from three levels solely by thoughtful means , and this is the most revolutionary point of it all 论文的创新之处有五点：一是从“尺度论”的角度，借助“内容论”来解读麦克卢汉的“媒介即讯息”的思想；二是从“内爆”的角度突出电子媒介的巨大力量；三是独创提出在电子媒介时代，人类延伸了自己的中枢神经系统之后，人类本身被逆转为媒介的延伸，成为电子媒介的一个节点；同时在本章节中提出中枢神经延伸之前的所有延伸为“可控延伸” ，而中枢神经被延伸时“可控延伸”逆转为“不可控延伸” ，并首次提出，困扰人类种种问题的重要原因是体内的中枢神经系统无法无缝地对接和控制被延伸出去的体外中枢神经系统；四是独自运用思辩的力量从三个层面综合论证了“媒介的终结”的观点，此处论证为本文最大创新之处，而此结论也将具有重大的理论与现实意义；五是根据以上几个部分的论述，对人类目前的总体状态作了一个定性的判断，即：我们这个时代的迷惘在于我们深陷于自恋的漩涡里难以自拔，在电子媒介以其固有的电力速度的推动下，我们走向自恋的尽头。
And then the worm epidemic situation curves are depicted with different parameters , from which we make some detail studies on the impacts of the parameters ( including the friendly worm propagation rate , the friendly worm number , the vicious worm propagation rate and the vicious worm number ) 根据网络分级的拓扑结构,良性蠕虫采用分级传播主动扩散策略nts2 。该策略将网络拓扑以接入层为临界点抽象成两级或多级,研究了在接入点内部不可控节点之间的et扩散算法,同时研究了et扩散策略稳定性的增强方法。
However , there are defects of current implementing of ipsec in performance , reliability , and security , because those implementation place ipsec protocol outside of platform . customizing operating system with ipsec protocol inside is a feasible method to resolve the problem . first of all , this paper analyzes embedded operating system and ipsec protocol ; secondly plans the implementing of embedded operating system based on linux and ipsec protocol stack model ; then provides arithmetic and integrating of ipsec protocol ; and concludes by analyzing the keystones and the trends 单纯在现有平台的基础上实现ipsec服务并不等于具备了高安全性，因为如果搭建的平台是不可控的，那么在上面的服务也就不具备可靠性，我通过将uclinux进行小型化定制，首先架构了一个的嵌入式操作系统，然后在linux内核基础上完整地实现了ipsec协议族，最后经过协议栈整合的算法和实现，将ipsec包运行在嵌入式操作系统平台之上。
To ensure the security of gi inspection , no approving method has been developed by far to drive the capsule endoscope but utilizing the natural peristalsis of gi tract . the uncontrollability of the capsule endoscope brings on some limitations in its functional extension in inspection , medication and surgery , such as temperature and ph measuring , medicament spraying , sampling , on - line sample analyzing , laser incising and rf cauterizing 胶囊内窥镜目前还没有实用的主动驱动方法,只能利用消化道自然蠕动作为胶囊内窥镜前进的动力。由于胶囊内窥镜不可控,限制了它的功能扩展,比如压缩空气喷药、吸取组织样品、在线样品分析、激光切割、射频烧灼等。完善的胶囊内窥镜系统需要在现有基础上加入安全有效的驱动控制,可调整姿态、行进及定位,从而扩大胶囊内镜检查的适应症、安全性与多功能性。
