本文以电场的三大定理、连续超张弛迭代算法、拉格朗日插值算法等原理知识作为理论基础，以 C 语言为编程工具，将由根据以上物理和数学原理所推导出来的模型转化为可以计算像管内电势的 CAD 程序软件。所编写的程序可以在给定像管参数和电极电位的情况下，计算圆柱形像管内任意一点的电位大小，并绘制出像管内的等势线；拉格朗日插值得到对称轴上任一点的电位值。 (In this paper, we base on the three theorems of the electric field, continuous ultra-relaxation iterative algorithm, and Lagrange interpolation algorithm. We use the C language as a programming tools, and transform the model derived above into a CAD software to calculate the electric potential in the image tube. In case the image tube parameters and electrode potential are known, the program written can get the potential of every point in the image tube, and plot equipotential lines inside the image tube. It can also get the potential of every point on the axis of symmetry by Lagrange interpolation. )

三次样条插值绘制光滑曲线，很有用的代码希望对大家有用(Cubic spline interpolation to draw a smooth curve, useful code hope to be useful)

利用逐点法绘制出图形，图形的绘制其实都是由折线组成的，只是每条折线的误差太小了，肉眼根本分辨不出来(use of the point-by-point drawing graphics, the graphics are actually drawn from the composition of the dogleg, only broken each of error is too small, the human eye can not be seen)

数字图像处理的课程设计，装起来有些麻烦，见附带的文本文档，可以做一些简单的栅格图像处理，但结合摄影测量获得的同名像点可以进行三维观测(digital image processing of curriculum design, and put up some trouble, see accompanying text documents, they can do some simple raster image processing, but the combination of photogrammetry was the same name as the 3D point can be observed)
