说明：  1.构建VI，产生两个随机数（0到1之间）并在仪表上显示两个随机数。仪表上分别设置标签“随机数1”和“随机数2”，使其中一个仪表显蓝色而另一个显红色。当红色仪表上随机数值比蓝色仪表随机数值大时，用一个圆形LED显示绿色，否则LED显示黑色。运行并观察结果。
(Construction VI, to generate the two random numbers (between 0 and 1) and two random numbers are displayed on the instrument. Set label " random number" and " random number" of the instrument, so that one instrument was blue and the other red color. Random value when the red meter blue instrument random value, with a circular LED display green, black or LED display. Run and observe the results.)
