LTE+&+LTE+Advanced+4G
The aim of this book is to give an integrated presentation of the<br />
specifications for Long Term Evolution (LTE) and LTE Advanced radio<br />
interfaces, so that the reader can gain an overview of
History of Wireless
The motivation to write about the History of Wireless comes from Auguste<br />
Comte (1798-1857), a French philosopher who is termed the father of positivism<br />
and mo

用于锂 - 硫电池的纳米结构金属氧化物和硫化物(1)
Lithium–sulfur (Li–S) batteries with high energy density and long cycle life are considered to be one of the most promising next-generation energy-storage systems beyond routine lithium-ion batteries.
模拟 PWM 输出控制灯的 10 个亮度级别
LED 一般是恒流操作的，如何改变 LED 的亮度呢？答案就是 PWM 控制。在一定的<br />
频率的方波中，调整高电平和低电平的占空比，即可实现。比如我们用低电平点亮一个 LED<br />
灯，我们假设把一个频率周期分为 10 个时间等份，如果方波中的高低电平占空比是 9：1，<br />
这是就是一个比较暗的亮度，如果方波中高低电平占空比是 10：0，这时，全部是高电平，<br />

一个按键控制的 10 级变速跑马灯试验
在本课中，我们要用一个按键来实现跑马灯的 10 级调速。这又会涉及到键的去抖的问<br />
<br />
题。 <br />
<br />
本课的试验结果是，每按一次按键，跑马速度就降低一级，共 10 级。 <br />
这里我们又增加了一个变量 speedlever，来保存当前的速度档次。 <br />
在按键里的处理中，多了当前档次的延时值的设置。 <
