图形符号及等值线追踪部分源程序(graphic symbols and contour tracking component source)

说明：  利用相场方法，计算枝晶生长，标记为相场动力学模型B。(Dendrite growth was calculated by phase field method and marked as phase field dynamics model B.)

对GPS信号实现三种算法的捕获，有串行搜索、并码搜索和并频搜索(GPS signal to achieve the capture of three algorithms)

说明：  选取四个点，自动判断是否在一个平面上。同一个平面上。则绘制一个多边形。不在一个平面，则以前三个点为底面，构成一个椎体。支持Move等转换命令，存图与开图，实现Jig交互绘制等。(Four points are selected to automatically determine whether or not they are on a plane. On the same plane. Draw a polygon. If it is not in a plane, the first three points are at the bottom, forming a vertebral body. Support Move and other conversion commands, save and open maps, Jig interactive rendering, etc.)

说明：  根据卫星坐标和接收站坐标来计算卫星高度角的一段程序，简单实用(A program for calculating satellite altitude angle based on satellite coordinates and receiving station coordinates is simple and practical.)
