  3. The poynting vector that represent the flow of electromagnetic power density on a sphere from a linear dipole antenna is approximated by the summation of the field of segmented line current as hertz dipoles

    以赫芝偶極之電磁場合成任意長度偶極天線在球面上電磁功率密度流之時變玻因亭向量。
  4. The distributions of velocity vector, vorticity. turbulent kinetic energy and some other detailed flow information in the field are obtained. the influence of electric field on the flow field is discussed and gives a deep insight on it

    3 、首次採用piv技術對荷電噴霧射流流場進行了測量，獲得了整個流場的瞬時速度、湍能、渦量等信息分布圖，研究了流場特性隨充電電壓的變化情況。
  5. In chapter 4, we discuss the method of vos abstraction based on temporal segmentation in detail. first we put forward affine modal, which is a kind of 3 - d motion modal of rigid body, compensate global motion vector based on this modal, and get the changed detection mask ( cdm ). then we introduce the conception of optical flow field, compute the local

    首先構建三維剛體運動的模型，提出一種計算模型的全局運動矢量的方法，並進行全局運動補償、變化檢測模板提取和連通域標記等步驟，然後引入光流場的概念，並介紹其計算原理和方法，用horn - schunck迭代法計算圖像中各點的局部運動矢量，並據此對變化檢測模板的結果進一步提取，獲得時域上分割的信息。
  6. In order to validate the correctness of the simulation, the flow velocity of x vector is measured to compare the flow field between the simulation and the experiment in wind tunnel. the results indicate that the flow field is improved and more stable than the original shield flow field. the tendency between the improved shield and the original shield from simulation is consistent with the tendency from experiments
