说明：  Qt开发中调用java。Qt 5.10以上版本可用。(Call Java in Qt development.)

说明：  基于FFT的谐波检测,采用快速傅里叶算法后得到原始波形中各次分量的频率和幅值特性，从中可以直接观测出各次谐波分量的频率和幅值信息. 程序1采用快速傅里叶算法后得到原始波形中各次分量的频率和幅值特性图 程序2输入信号经过FFT变换得到的频谱特性图 程序3对输入信号进行采样，应用一维小波变换函数进行三层小波分析(Based on FFT harmonic detection, the frequency and amplitude characteristics of each harmonic component in the original waveform are obtained by using fast Fourier algorithm, from which the frequency and amplitude information of each harmonic component can be directly observed In program 1, the frequency and amplitude characteristics of each component in the original waveform are obtained by using the fast Fourier algorithm The spectrum characteristic diagram of program 2 input signal through FFT transformation Program 3 samples the input signal and applies one-dimensional wavelet transform function to three-level wavelet analysis)

：某大学开田径运动会，现有12名选手参加100米比赛，对应的运动员号及成绩如表所示，请按照成绩排名并输出，要求每一行输出名次、运动员号及成绩。要求用冒泡法排序。-: A university open track and field sports, the existing 12 players compete in the 100-meter race, the corresponding numbers and achievements of athletes, such as shown in the table, please follow the performance ranking, and output, requires that each line of output ranking of the number and performance athletes. Required to use bubble sort method.

说明：  打印一条文字“”你好世界“”你好python“”最基础的python语言了解一下(Print a text "Hello World" and "Hello python". Learn about the basic Python language)
