说明：  波束宽与小区覆盖大小的关系，以及半功率带宽与滚降系数的关系(Beam width and the size of cell coverage, as well as the half-power bandwidth and roll-off coefficient of the relationship between the)

使用Acrgis Engine 的java api 开发的创建一个shape文件-Acrgis Engine using the java api to create a shape the development of documents

实现字符串比较的功能，是C语言课程老师布置的作业，(To realize the function of string comparison is the assignment of C language course teachers.)

说明：  潜在特征 机器学习 数据挖掘 数据分析 代码(latent feature ml data mining data analyst code)

晶振12M，定时器溢出中断每一秒触发一次，中断函数控制秒数加一，当秒数等于99时归零。秒数由两位数码管动态显示。定时器的溢出中断的暂停和继续由两个外部中断控制。外部中断按下后由其相应的中断程序使能或失能定时器溢出中断。定时器部分参考叶大鹏老师代码，外部中断代码自行编写。亲测有效。

利用grads计算ncep-fnl资料的的水汽通量及水汽通量散度(The calculation of water vapor flux and water flux divergence about the ncep- FNL data by using grads)

多径衰落信道下面的CP-OFDM系统，以及AWGN信道。(The CP-OFDM under multichan.)

处理肌电信号，得到短时傅里叶变化下的中值频率和肌肉激活度进行下一步的分析(The electromyography signal is processed, and the median frequency and muscle activation degree under the condition of short time Fourier transform are analyzed)

说明：  用三个按键控制pwm输出 key0控制是选着显示/改变频率或占空比 key1控制增加 key2控制减少 数码管显示频率或占空比 频率单位默认Hz（500-20KHz） 占空比范围（0.1-0.9）(Control PWM output with three keys Key0 controls display/change frequency or duty cycle optionally Key1 controls the increase Key2 controls are reduced Digital tube display frequency or duty ratio Frequency unit default Hz (500-20khz) Duty cycle range (0.1-0.9))
