所谓边界就是某个封闭区域的轮廓,使用边界命令可以根据封闭区 域内的任一指定点来自动分析该区域的轮廓,并可通过多段线或面 域的形式保存下来,如图6.1所示。 启动创建边界命令 Boundary的方法有如下几种:

2.1电阻串并联的等效变换 2.2电压源与电流源及其等效变换 2.3支路电流法 2.4节点电压法 2.5加原理 2.6戴维宁定理与诺顿定理 2.7受控电源电路的分析 2.8非线性电阻电路的分析

4.1三相电压 1三相电动势的产生 在两磁极中间,放一个线圈

5.1非正弦周期量的分解 5.2非正弦周期量的有效值 5.3非正弦周期电流的线性电路的计算 5.4非正弦周期电流电路中的平均功率

Research methods Qualitative Vs quantitative Understanding the relationship between objectives(research question) and variables is critical Information≠Data Information=data analysis Planning in advance is a must To include how data will be analyzed

How experts make decisions in the real world Descriptive method Stress, time-pressure, dynamic conditions, ambiguous information, and ill-defined goals Heuristics may introduce bias but can be very powerful Other related research areas
