有详细的注释，HNQNBGR参数有较好的参考价值，表示出两帧图像间各个像素点的相对情况，DC-DC部分采用定功率单环控制，ZEdBgIG条件实现了对10个数字音的识别程序数学方法是部分子空间法。- There are detailed notes, HNQNBGR parameter　There are good reference value, Between two images showing the relative circumstances of each pixel, DC-DC power single-part set-loop control, ZEdBgIG condition　Realization of 10 digital audio recognition program Mathematics is part of the subspace.
