Labview的DataGridView应用例程(1.基于Labview的DataGridView应用例程； 2.可用作优化界面风格； 3.对表格的操作更强大；-1.It is base on labview example of Data Grid View 2.It can be used to optimize the interface 3.It has the strong ability of operating the table.)

模拟了弹簧上的物体在发生阻尼振动时的运动规律。弹簧的阻尼振动与物体释放时的初始位置、物体的质量，弹簧的劲度系数，以及阻尼系数有关，本程序设置了可以改变这些值的数值输入控件，通过改变这些数值，实现对弹簧阻尼振动的模拟，实时波形曲线记录了相应时刻弹簧的位移和速度，仿真图模拟了物体在弹簧牵引下的运动状态。时间轴可以将时间进程加快或放慢，从而更清楚地展现运动过程。

先将字符串转化为像素图，再将像素图还原成二维数组。将二位数组转化为布尔数组。然后用一个顺序结构，第一帧放入比较程序，即显示汉字并闪烁程序。第二帧循环移位程序。第三帧屏幕关闭程序。(First string into a pixel map, and then reduced to a two-dimensional array of pixel map. The two-digit group into a Boolean array. Then a sequential structure, comparing the first frame into the program, the program that displays characters and flashes. The second frame cyclic shift procedure. The third frame of the screen to close the program.)
