说明：  　　 paek变换 park转换，也称派克变换，英文为Park transformation,为现在占主流地位的交流电机分析计算时的基本变换。在电力系统分析和计算中，park转换具有重要的理论和实际意义。(paek transform park conversion, also known as Park transformation, the English for the Park transformation, for the now dominant in the calculation of AC motor analysis of the basic transformation. In power system analysis and calculations, park conversion has important theoretical and practical significance.)

99秒马表，在Proteus设计两个数码管动态显示及一个键盘SP。在ucos下结合keil完成开始时，显示“00”，第1次按下SP后就开始计时。 第2次按SP后，计时停止。第3次按SP后，计时归零。 (99 seconds stopwatch, two in the Proteus design dynamic digital tube display and a keyboard SP. Keil in combination ucos completed under the beginning of the show " 00" , 1st timer after pressing the SP. 2nd by SP, the time to stop. The 3rd by the SP, the time zero.)
