计算机图形学在四探针技术有限元理论中的应用

Application of Computer Graphics in FEM Using a Fourpoint Probe

在四探针测试半导体薄层电阻的有限元（ＦＥＭ）理论中，四根探针在样品上的位置靠键盘输入有限元剖分节点标号来给定．当测试样品的形状较为复杂时，节点标号人工很难确定．本文提出在计算机视频显示处于图形模式采用鼠标输入的方法，这种方法直观、快捷，为实际应用提供了很大的方便．

In FEM using a fourpoint probe, the position of four probes on a sample depends on keyboard inputing nodes. When the shape of the sample is complex, it is difficult to determine node numbers. In this paper, a method of using mouse input is presented. This method that is audiovisual and quick, provides convenience in practice.
