| 摘 要： | “调频波频谱动态演示ＣＡＩ软件”是在Ｗｉｎｄｏｗｓ９５环境下，采用Ｖｉｓｕａｌ Ｂａｓｉｃ ４．０ｆｏｒ Ｗｉｎｄｏｗｓ开发的。开发过程中，采用了动态链接库ＤＬＬ和数据文件调用等技术手段，并借助了ＦＯＲＴＲＡＮ５．１精确计算Ｊｎ（ｍｆ）。该软件能够以调频指数ｍｆ为控制变量，精确地动态演示调频波频谱，且能够随机选取频谱图保存，以便观察，比较。

| Abstract: | The dynamic demo CAI software for FM wave spectrum is developed by means of Visual Basic 4.0 for Windows 95 .The related technical means,such as,Two dimension curve demo, Dynamic Link Library and Data file employment,are used in the development process and J n(m f) is calculated accurately with FORTRAN 5.1.With FM factor m f as a control variable, the CAI software can demonstrate FM wave spectrum accurately. And you can select some spectrum image to save on the screen at random so as to have an observation and comparison. |
