说明：  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.)

安卓聚合阅读器源码是一套基于安卓的RSS阅读器项目源码。内置三张壁纸，换肤功能。项目已经内置了很多RSS源，并且进行了分类。显示模式有白天、夜间两种显示模式。项目文章显示使用的自定义字体，项目本身内置收藏和分享功能，可以分享到QQ空间、新浪微博、腾讯微博、人人和豆瓣。只是暂时不能自定义添加RSS源，相关功能模块正在开发中。(Android aggregation reader source is a set of Android based RSS reader project source. Three built-in wallpaper, skin function. Project has built a lot of RSS source, and carried out a classification. Display mode has two kinds of display modes during the day and night. Project articles show that the use of custom fonts, the project itself in the collection and sharing functions, you can share to QQ space, micro-blog Sina, Tencent micro-blog, everyone and broad bean. Just temporarily can not be customized to add RSS source, the relevant functional modules are being developed.)

可以通过get请求或者post请求从服务器上获取到json格式的字符串，并解析json格式的字符串。
