用Mega128单片机驱动蜂鸣器，实现音乐的播放功能，程序经过优化，声音比其他版本悦耳。(MCU-driven with Mega128 buzzer to realize the music playback capabilities, the program is optimized, the sound better than any other version of the musical.)

直流无刷电机的控制研究（硕士论文）以DSP为核心的控制包括硬件和软件(Brushless DC Motor Control (Master thesis) to control the DSP core hardware and software)

推挽式DCDC变换器的闭环仿真，电压闭环，输出稳定(DCDC converter push-pull-loop simulation, the voltage loop, stable output)

真空机组先启动SK-30水环真空泵带压力降到6.5 KPa（此时真空机组的抽速是SK-30的抽速）启动ZJP-1200（此时真空机组的抽速是ZJP-1200抽速）待压力降到4 KPa启动ZJP2500（此时真空机组的抽速是ZJP-2500抽速）待压力降到1kpa时最后启动ZJP5000（此时真空机组的抽速是ZJP-5000抽速）到100Pa达到使用真空度时时就可以关闭机组(Vacuum unit first start SK-30 water ring vacuum pump with pressure drops below 6.5 KPa (pumping speed of the vacuum unit at this time is SK-30 pumping speed) start ZJP-1200 (pumping speed of the vacuum unit at this time is ZJP-1200 pumping speed ) until pressure drops below 4 KPa start ZJP2500 (pumping speed of the vacuum unit at this time is ZJP-2500 pumping speed) until the last start when pressure drops 1kpa ZJP5000 (pumping speed of the vacuum unit at this time is ZJP-5000 pumping speed) to 100Pa achieved using vacuum unit can be closed from time to time)
