VB自制文字打字动画特效，文字一个一个出现，打出来的一样，这种文字特效也是很不错的哦。这种文字动画可用于软件介绍中，或做一些课件的时候能用到。

说明：  这是个非常好用的实验，主要是差分放大带电路，和负反馈放大电路(The substitution of some rolling friction for sliding friction results in a very considerable reduction in friction.)

用于电动汽车的充电，恒压恒源，稳定充电。(For charging electric vehicles, constant voltage and constant source, stable charging.)

说明：  设计一个串行数据检测器，当连续输入三个或更多1时输出1，否则输出0(Design a detector for serial data It outputs 1 when three or more 1 input continuously and outputs 0 otherwise)
