  2. Finally, using the low loss 3 - db three port network as power dividing and combing network and using hmmc 5040s fabricated by agilent co. as single - way amplifiers, with the help of e - plane waveguide to microstrip transition, we have designed a two - way power combing circuit with waveguide as interface ports. in 33ghz ~ 35ghz, the measured saturated output power is about 170mw, and the combing efficiency estimated is greater 70 %

    最後，採用我們設計的3 - db三埠網路作為功率分配、合成網路，以常用的微帶e面探針作為微帶-波導過渡結構，採用agilent公司hmmc5040作為放大單元，製作出了波導介面的兩路合成電路，在頻率為33 35ghz實測飽和功率達170mw ，合成效率高於70 。
  3. Introduction, network laws and components, introduction to circuit analysis, network node voltages and mesh currents, network properties ? thevenin ' s and norton ' s equivalent sources, operational amplifiers, equivalent circuits for three - terminal networks and two ? port network

    簡介、網路的組件和網路定律、網路分析與節點電壓和綱目電流，網路的性質-載維寧和諾頓的等效電源、運算放大器、三接端網路的等效電路與雙埠網路。
  4. At first, based on conservation of energy, a three - port network is brought up. then, after discussing the power flow in the three - port network, a systematical procedure is derived to generate all possible minimal configurations

    首先，根據能量守恆定律，建立了pfc的三端模型：然後，分析三端之間的能量流圖，推導出pfc的拓撲結構。
  5. Firstly, the interrelated knowledge about network security vulnerability is introduced in this thesis, include definition, cause of formation, character and attribute, sort and detecting method. different kinds of skills and characteristics of port - scan technique are analyzed and compared in this thesis. then, the virtues and defects of three kinds of fingerprint technique of os - detect are also analyzed and compared

    本論文首先介紹了網路安全漏洞的相關知識，包括漏洞的定義、成因、特徵和屬性、分類及檢測方法，對各種埠掃描技術及其特點進行了分析和比較，介紹了三種探測操作系統的指紋技術，並分析了它們的優缺點。
  6. Under the presently conditions, we have designed a low loss 3 - db three port network available in power combing or dividing. since without resistive material, it is different from conventional 3 - db wilkinson hybrid and can fabricated on soft substrate, so simplify technology of circuit fabrication

    我們設計出了不同於一般常用的wilkinson電橋的、可用作功率合成與分配網路的低損耗3 - db三埠網路，在32ghz 37ghz頻率范圍內，插損約為0 . 2db 。
  7. So most software can be test on the pc and can be transplanted to gateway after all is ok. the platform is designed from top to bottom, at first, the functionalities and interface of the three module should be specified clearly, and then go into the details of it, came back to modify the interface made before. the tree modules are connected through pci bus. adsl module implements the adsl modern as the atu - r ; the network interface consists of two part, wileless lan ( it is optional ) and lan, can connect with two different lan. the main control module controls the action of the others which is made of sdram, microcontroller, flashrom and serial port

    為了設計方便，整個硬體平臺按照自頂向下的設計方式，首先按照功能分為三部分： adsl模塊，網路介面模塊，主控模塊，這些模塊之間採用流行的pci總線相連接，規定模塊之間的介面關系，然後進行細化，反饋回來完善原先定義的介面關系。其中， adsl模塊可作為單獨的adsl數據機使用，起到atu - r的功能：網路模塊由兩部分組成，無線lan和lan介面（其中前者為可選項） ，可以連接wirelesslan和lan 。主控模塊起到協調的作用，包括sdram 、微控制器、 flashrom 、串口等。
