用于机床系统参数测试与分析，可以测试、位移、速度、加速度、温度等数据-System parameters for machine testing and analysis, testing, displacement, velocity, acceleration, temperature, and other data

利用加速度计算位移，通过FFT快速傅里叶变换实现，只需调整滤波频率-Displacement of the acceleration calculated by the fast Fourier transform FFT, simply adjust the filter frequency
