There are three parts in our design: first, the dual-band branch line coupler provides two equal-power signals with 90° or -90° phase difference in each operating band. Second, the wideband switching circuit controls the two output powers of branch line coupler to excite the antenna structure for producing linear polarization wave or circular polarization wave. Third, the L-shaped fed conventional planar patch antenna is provided to overcome the coupling effect.

整体架构包含三个部分：L形电容耦合馈入式平面天线是为了克服平面式微带天线窄频的缺点；双频枝干耦合器提供天线在操作的两个频率点上各输出两组相差正九十度与负九十度的讯号，最后宽频的切换电路是将枝干耦合器的两组讯号作分配用以激发不同方向的天线以产生线性极化模态或同时激发两个垂直的天线以产生圆形极化模态。

I read Wang Ming's "50 Year of CCP" recently, it's maybe a forbidden book about abusing Chairman Mao and distorting Party history, but Wang has a beautiful pen and learn theory very well, after I finished the book I have two achievements, first is knowing that Wang has living to the ending of Culture Revolution and he had also take big position after PRC was established. Second is I understand the major convergence between Mao and Wang is whether Maxism can be Chinalized, Wang conclude Maoism is total Personal Adorement, to think peacefully it's reasonable, and after Mao there are "2 If, 3 Representer, Cat and 2 Must" Theories, but Wang's flatory to USSR was also unacceptful, all in all Stalin also advocate Personal Adorement movement.

最近还看了王明的《中共50年》，这可能算一本禁书吧，是骂毛主席歪曲党史的，不过王的文才不错，理论学的也好，看完两个收获，第一是知道了王竟然一直活到文革快结束时，建国后还当过不小的官，第二是理解了王和毛的主要分歧是马列主义能不能中国化的问题，王是极力反对毛泽东思想和马列中国化的提法，认为是极端的个人崇拜，平心而论有些道理，而在毛之后"两个凡是、三个代表、猫论、两个务必"都陆续出台，但王对苏联的极力美化也是存在问题的，毕竟搞个人崇拜搞得凶的是斯大林。

Primarily, the thesis assays the condition of network framework, the network was divided into three levels in terms of network management in order to establish the distributed method ,and still pointing out the intention and denotation of studying the Topology Discovery.Next, the thesis analyzes SNMP protocol minutely, including its development, principle, and the Network Management system that established on the SNMP protocol. Have analysed MIB in detail and the application way of MIB in network management .The thesis also assays the ICMP protocol, describing its working principle and the format of datagram minutely , and describing two important tools of ICMP- Ping and TraceRoute in detail. On the base of upper analysis, the thesis expounds a kind of distributed Topology Discovery project, and book it in one autonomy system. Topology Discovery was divided into two levels in terms of network management, and analyses the way of linking up between the two level. The thesis minutely assays Router-Level Topology Discovery technology basing on SNMP and Subnet-Level Topology Discovery technology basing on ARP and ICMP. According to these analyses, the thesis explores the specific methodology and the technology of XML data object which using the WinSNMP API to achieve topology discovering system on the development platform of Visual C++, and also analyses the technology of topology analysis and topology graph minutely. Moreover, the thesis assays the technology of basic firewall and Topology Discovery response strategy. Finally, the thesis analyses the underlying blind problem of the topology finding, and also analyses the reason that the blind problem produced and the way that reduced. The distributed algorithm that this paper puts forward has a certain directive significance in wireless network or other fields.

They were fighting, albeit discreetly, to open the intellectual world to the new science and to liberate intellectual life from ecclesiastical phi losophy and envisioned their work as contributing to the growth, not of phil osophy, but of research in mathematics and physics.

难句类型：复杂修饰、插入语、省略、抽象词解释：本句再一次出现两个and连接三个不属于同一层面的成分的情况：第一个and 连接两个并列的不定式，第二个and的级别较高，连接前后两个并列的句子，and之后相当于省略了主语they。

Moreover, A hybrid algorithm, ALHybrid, which is made of the algorithm LIDBSO and the algorithm AprioriIpv, is designed.
