流管中流体震荡模拟

/*
    This class is a basic extension of the Frame class.  It can be used
    by an applet or application.  To use it, create a reference to the class,
    then instantiate an object of the class, and call the show() method.


    example:

    main themain;
    themain = new main();
    themain.show();

    You can add controls or menus to main with Cafe Studio.
