  1. In this paper, first, the study of the distribution of electromagnetic field, energy, power, reflection coefficient and transmission coefficient in waveguide with piecewise different dielectric constants are studied. then, the behavior of propagation of am signal and gauss pulse signal through the waveguide are simulated by magic code ， and the plots of electromagnetic field, energy, ponyting vector and their spectrums at different time and different position are obtained. and, the group velocity and energy velocity of wave packet through barrier are calculated

    從90年代開始， emig和martin 、 landauer等人研究了分段填充不同介質的波導中的電磁脈沖的傳播。在本論文中，作者首先推導出分段填充不同介質的波導中的電磁場分佈、能量、傳輸功率以及反射系數和傳輸系數的表達式，然後，採用magic程序模擬了這種波導結構中電磁波的傳播情況，得到了在不同時刻和不同位置處的電磁場分布圖、能量圖、坡印廷矢量圖以及它們的頻譜圖，並由模擬結果計算了波包穿越勢壘的群速和能量速度。
  2. Secondly, the software definition, software overall design and detail design including the selection of the development mode and the development tool, the flow chart of the simulation software of illumination, the computational simulation models of illumination of the headlamp bulb, the reflector and the measure screen, the process of simulation result and the calculation efficiency, and so on, are presented in this paper

    本文給出了汽車前照燈模擬計算軟體的定義、總體設計方案和軟體的具體設計方案，包括軟體開發方法和開發工具的選擇，照度模擬計算軟體的開發流程圖，燈泡、反射鏡和配光屏幕的照度模擬計算的計算機模型，模擬計算結果的處理和軟體的計算效率問題等。
  3. Picture that put forward in the article graph and data structure reciprocal mapping support not merely to map graph from data structure efficiently, besides, regard graphics element as a unit, analyze and discern to user ' s modified graph, produce the corresponding data structure automatically, maintain consistency of graph and data structure efficiently on the foundation of expanding case graphic tools effectively, we direct against the intrinsic characteristic of traditional waterfall model, proposesmall loop model to software analysis based on graph and data structure reciprocal mapping solve problems of slow information feedbackand high track back cost efficiently

    文中提出的圖數互逆映射的思想，不僅對數據結構到圖形映射進行高效率地支持，同時，以圖形元素為單位，對用戶修改後的圖形進行分析和識別，自動生成相應的數據結構，有效地維護了圖數一致性。在對case圖形化工具進行有效擴展的基礎上，我們針對傳統瀑布開發模型的固有特點，提出了基於圖數互逆映射的軟體分析小循環模型，有效解決了傳統軟體分析設計階段信息反饋慢、回溯代價高等問題。
  4. In the end of this paper, we introduce that in the context of weather radar observations the enhancement of thin - line features in meteorological radar reflectivity images is addressed using a wavelet - based analysis. passing the thin line highlighted image into forecast system to complete the feature identification, we can get basis element for thunderstorm forecasting

    本文最後介紹了採用小波變換的方法對濱州雷達資料的反射率圖像進行處理，得到特徵線增強后的圖像，將其輸入自動預報系統實現特徵識別，可為雷暴預報等提供某些初步識別判據。
