Description: 1、 利用8031作为主控制器组成一个电子跑表，采用4位LED显示器。
2、 上电或RESET后能启动显示当前（时：分）：首次上电复位显示为0时0分，以后各次RESET均显示正确的当前时间。
3、 当按下START键时，作为跑表使用，显示范围是：000.0-999.9秒，当按下STOP键时，跑表停止运行，并保留所停位置的时间显示不变。
4、 利用H键作为时钟校正，即当按下H键时，显示的当前小时值以每秒加一的速度递增（24点即为0点），利用N键作为分校正，使用方法同H键，但60分钟即为0分。

Description: 基本上程序还是DEMO程序,程序并没有采用定时器来生成PWM,而是采用延时循环来实现,这样就做不了其他事情 了,但实际上只需要将主循环转换为定时器中断处理即可,很简单.这个是参照市面上邦定IC RGB控制功能来做的,这应该是采用单片机方案最便宜版本之一了
-Basically the procedure or DEMO program, the program does not use a timer to generate the PWM, instead of using the delay loop to achieve, so can not do other things, but in fact only need to convert the main loop for the timer interrupt processing can be , is very simple.

Description: Crystal growth concepts have been fundamental to many areas of science for
quite some time. Disciplines as diverse as mineralogy, meteorology, biology,
astrophysics and chemical engineering have contributed to and benefited from
crystal growth concepts. It was, however, not before the onset of the materials
science era and the mushrooming development of the electronic and optical
materials industries that crystal growth began to develop into a discipline
in its own right. In concerted efforts, solid-state and crystal-growth
research have led to many new materials and devices. Their applications have
had a great impact on modern life. Today crystal growth forms one of the main
pillars of modern technology.
