用于工业控制方面.常见的板卡操作.板卡型号为812板.-for industrial control. Common card operation. Card Model 812 board.

实现公历与农历的转换一般采用查表法按日查表是速度最快的方法但51 单片机寻址能力有限不可能采用 按日查表的方法除按日查外我们可以通过按月查表和按年查表的方法再通过适当的计算来确定公历日所对应的 农历日期本文采用的是按年查表法最大限度地减少表格所占的程序空间-Limited can not be used In addition to a daily look-up table method of daily things that we can search through monthly and annual look-up table look-up table method and through the appropriate calculations to determine the calendar day corresponding to the Lunar date of this paper is the annual table look-up table method to minimize the space occupied by program
