说明：  看门狗定时器（WDT，Watch Dog Timer）是单片机的一个组成部分，它实际上是一个计数器，一般给看门狗一个数字，程序开始运行后看门狗开始计数。如果程序运行正常，过一段时间CPU应发出指令让看门狗置零，重新开始计数。如果看门狗增加到设定值就认为程序没有正常工作，强制整个系统复位。(Watch dog timer (WDT, watch dog timer) is a component of single chip microcomputer. It is actually a counter. Generally, it gives a number to the watch dog. After the program starts to run, the watch dog starts to count. If the program runs normally, after a period of time, the CPU shall issue an instruction to set the watchdog to zero and start counting again. If the watchdog increases to the set value, the program will not work normally, and the whole system will be forced to reset.)

在Keil环境下，使用C8051F120对SD卡进行操作，(In the Keil environment, use the SD card to operate on the C8051F120,)

本文论述了在控制的一个重要方面电网连接的电源转换器，即检测基波正序分量的电网电压不平衡和扭曲的条件下。明确地,提出了一种积极的基于一种新的序列检测器双同步坐标系的解耦锁相环（双dq–PLL），完全消除了检测误差传统的同步参考框架（SRF–锁相环PLL）。(This paper deals with an important aspect in the control of grid connected power converters, that is, detecting the fundamental positive sequence components of the grid under unbalanced and distorted voltage conditions. Clearly, a positive decoupling PLL a new sequence detector based on dual synchronous coordinate system (double DQ - PLL), the complete elimination of the traditional synchronous reference frame detection error (SRF - PLL PLL).)

Dos下图形界面的八皇后小游戏。 本程序在TC++3.0下编译调试通过！采用了Borland公司提供的图形库Graphics. 为了能使本程序脱离c/c++环境独立运行，我将图形驱动 EGAVGA.BGI以及字库TRIP.CHR和SANS.CHR均转换为相应的.obj文件，然后链接到可执行文件EIGHTQUEEN.EXE中！-Dos under a graphical interface Queen"s small eight games. The procedures under the TC 3.0 compiler debug through! Borland used to provide the graphics library Graphics. In order to enable this process from the c/c environment operate independently, I will drive EGAVGA.BGI graphics and font TRIP.CHR and SANS.CHR were converted to the corresponding. Obj file, and then link to the executable file which EIGHTQUEEN.EXE !
