将一个无序数组排为升序数组或降序数组，且不丢失原来数据。-A disorderly array of row arrays for ascending or descending array, without loss of the original data.

用汇编编写，接收从键盘输入的两个数，计算它们的假减乘除。-used to prepare the compilation, receiving input from the keyboard to the two the number of false calculation by multiplication and division.

8052单片机和计算机串口通信的试验。已经成功演示，上位机用的是vb写的程序。-8052 single-chip serial communication and computer tests. Have successfully demonstration PC using a program written in vb.

装置的功能是对温度进行实时监测与控制。由温度传感器DS18B20对温度进行采样和转换成数字信号送入单片机，并与设定的报警温度上、下限值进行比较，信息通过LCD显示出来。如实时温度超过设定的上、下限值，一方面由LCD显示信息，并发出警报声；另一方面自动控制继电器（Relay）开接通或断开，从而控制加热源的开与断，达到对温度进行实时控制的目的。-Device" s function is real-time temperature monitoring and control. Temperature by the temperature sensor DS18B20 sample and converted into a digital signal into the microcontroller, and with the set alarm temperature of the upper and lower limit comparison information through the LCD display. Such as real-time temperature exceeds a set upper and lower limits on the one hand by the LCD to display information, and the alarm sound the other hand, automatic control relay (Relay) to open turn on or off to control the opening and the heat source off, to achieve real-time temperature control.

本动画先显示一些提示信息，然后按任意键进入，只见一个方框向中间由大变小，并留下痕迹，然后出现一个心，按空格重复出现心，按其他键将重复,按Q键退出程序，。-the animation first showing some hints information, and then by arbitrary keys to enter, I saw a box to the middle into small, and leave your mark, and then there appears a heart by heart spaces repeated by other keys to repeat, according to withdraw from the Q key procedures.

基于C51单片机的串行数据传输，带有工作协议，可用于简单的无线串行通信。-C51-based Microcontroller serial data transmission,with a working agreement,which can be used for a simple wireless serial communication.
