非常好，非常棒，非常不错的android内存管理。(android memory manage)

AutoHotKey c 项目源码下载

SignalA修改后的源码，支持android2.2及以上(SignalA modified source code, support android2.2 and above)

该电源以单端反激式DC-DC变换器为核心。市电通过自耦式调压器，隔离变压器，整流滤波后产生直流电压，经DC-DC变换得到题目所需输出电压，实现了开关稳压电源的设计。(The power to single-ended flyback DC-DC converter at the core. City through the auto-type voltage regulator, isolation transformer, rectifier filter DC voltage generated by the DC-DC conversion has been the subject output voltage required to achieve a switching power supply design.)

智能电源插座程序 用51单片机程序编写，数码管显示(Smart power outlet with 51 microcontroller programming procedures, digital display)

脉冲宽度调制是一种模拟控制方式，根据相应载荷的变化来调制晶体管基极或MOS管栅极的偏置，来实现晶体管或MOS管导通时间的改变，从而实现开关稳压电源输出的改变。这种方式能使电源的输出电压在工作条件变化时保持恒定，是利用微处理器的数字信号对模拟电路进行控制的一种非常有效的技术。脉冲宽度调制是利用微处理器的数字输出来对模拟电路进行控制的一种非常有效的技术，广泛应用在从测量、通信到功率控制与变换的许多领域中。(Pulse width modulation (PWM) is an analog control method, which modulates the bias of transistor base or MOS gate according to the change of load, so as to change the turn-on time of transistor or MOS and realize the change of output of switching regulated power supply. This method can keep the output voltage of the power supply constant when the working conditions change. It is a very effective technology to control the analog circuit by using the digital signal of the microprocessor. Pulse width modulation (PWM) is a very effective technology to control analog circuits by using the digital output of microprocessors. It is widely used in many fields, from measurement, communication to power control and conversion.)
