  1. It is very important to estimate the basic parameters in helicopter preliminary design. neural network ( nn ) has the advantages in estimating accuracy and generalization over traditional methods. however, there are some difficulties in using nn, e. g., how to select a proper network structure and the number of hidden layers. in this paper, structure and connection weight of a three - layer nn are optimized by genetic algorithm, and the optimized network is applied to helicopter sizing. the proposed method can not only give an optimal nn structure and connection weight, but also reduce the prediction error and has the capability of self - learning when the latest data are available. furthermore, this method can be easily applied to helicopter design systems

    在直升機初步設計階段估算其基本參數是很重要的.神經網路的通用性和精度比傳統的估算方法有更多的優勢，但是在應用神經網路時存在如何選擇合適的網路結構和隱層節點數目等一些困難.應用遺傳演算法優化三層神經網路結構和連接權重，並將優化得到的網路應用於直升機參數選擇中.該方法不但可以給出一個最優的神經網路結構和連接權重，而且降低了估算誤差，具有及時應用最新數據學習的能力.此外，該方法易於在直升機設計系統中得到應用
  2. Zno varistors have been widely used in electronic and electrical power devices and systems because of excellent nonlinear v - i characteristics and high absorbance of electric current surges. with the smt ( surface mounted technology ) development, traditional zno varistors can not meet the multilayer thin films lamination structure nappe varistor ceramics and metal electrode low temperature co - fire need. however, the best character of zno - v2o5 varistor can sinter in common furnace during lower temperature ( 900 ), not only settling the problem relate to upon, but also saving energy sources

    Zno壓敏電阻因其優異的v ? i非線性和較高的浪涌吸收能力而廣泛應用在電子、電力設備系統上。然而，隨著表面貼裝技術（ smt ）的發展，傳統的zno壓敏陶瓷不能滿足多層膜獨石結構疊層壓敏電阻元件陶瓷與金屬電極低溫共燒的需要。而zno ? v2o5系壓敏陶瓷的最大優點是能用普通燒結爐在較低溫度（ 900 ）下燒結，不僅解決了以上問題，還大大節約了能源。
  3. Then, it analyzed can and canopen application layer, including : real - time characteristics of can, the core of canopen - od, all kinds of communication objects, the allocation of cob - id and some device profiles. and xcanopen was brought forward for implementing of canopen in power line communication. then, on the reference design platform of freescale - agilent, xcanopen ’ s two standard software interfaces, bottom driver and function of communication and network management based on canopen were implemented

    本文詳細分析了低壓電力線通信數據機的結構與工作原理;分析了can協議及其可以保證數據實時可靠傳輸的實質，剖析了應用層協議canopen ，著重解釋了canopen的核心?對象字典od 、各類通訊對象、標識符的分配，以及一些設備子協議（ deviceprofiles ） ，並提出了在電力線通信上實現canopen的解決方案? xcanopen框架;在基於freescale - agilent電力線通信的參考設計平臺上實現了xcanopen的兩個標準軟體介面，電力線通信底層驅動軟體的設計以及基於canopen協議棧的節點通信和網路管理功能，達到了使用canopen協議來實現電力線通信的標準化模塊的目的;最後，在canopen數據通信的實時調度上做了進一步的改進探索研究。
