基于矩量法仿真的笼形天线宽带化设计 (Method of Moments simulation cage antenna design is based on broadband)

说明：  通过模拟电荷法计算特高压直流输电线路的标称电场(Calculation of the nominal electric field of transmission line by the method of simulated charge)

欧拉角表示法具有简便、几何意义明显等优点，同时姿态敏感器可以直接测出这些参数，能较方便地求解用这些姿态参数描述的姿态动力学方程。但采用欧拉角的姿态描述方法存在奇点问题，且需多次三角运算。而采用四元数表示方法则可以避免这些问题。(conversion between euler angle and quaternion method)

The study consisted of an introduction, three scans performed for each of the eleven scanners, and an adjacent interview. We utilized a within-subject design. The dependent variables were task completion time and reliability, by which we mean the share of successful scans within a task completion time below 15 seconds. The independent variables were the barcode scanners as listed in Table 1. For each participant the study was recorded on video. We also transcribed comments the participant made during the tasks.

说明：  FEA 有限元计算matlab很早以前编制的程序，适应新的matlab环境。(FEA finite element matlab long ago programmed to adapt to the new matlab environment.)
