摘　　要：单片机是将运算器、存储器、定时器、模数转换器和串行通信接口等集成在一个芯片上的小型计算机系统,它可以被嵌入到各种自动控制器和智能电子产品中。由于它体积小、成本低,给人们带来了极大的便利,所以它的应用日益广泛并长盛不衰。相应地,它的应用技术也不断发展。现就单片机应用中几个问题的解决方法加以说明,与各位同行交流。这几个问题是:累积量的掉电存储问题、多字节除法问题、转速的检测问题和交流电设备的控制问题。Microcontroller is a small computer system that integrates ALU,memory,timer,ADC,UART,etc in one chip.it can be embedded into many kinds of controllers and intelligent electronic products.It takes convenience to people with its small size and low price,so it is widely used for a long time.The technique of microcontroller application develops constantly.Now the solutions of several problems about microcontroller application are illuminated here for exchange with colleagues.The problems are：the storage of cumulating variable at power off,multi-byte division,the detection of rotating speed and the control of facilities by AC power.
