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.)

说明：  A UI project source code that imitates storm video and audio. The imitated interface includes menu pages, home pages, classification pages, etc. The local analog data used for all data in the project. The imitated degree will be problematic in layout and display on high-resolution devices. The resolution of 480 x 800 should be just right.

    首先是布局文件,布局中需要一个HorizontalScrollView用来承载所有标题和指示器,注意HorizontalScrollView中只能有一个子布局,所以要添加一个Linearlayout(竖向的),这里为什么是竖向的呢?因为这个线性布局中要加入一个横向的线性布局用来动态增加所有标题内容,和一个标题下面的指示器.
