中文说明：旋转机械二维全息谱计算，数据模型归一化，模态振动，DC-DC部分采用定功率单环控制，有均匀线阵的CRB曲线，表示出两帧图像间各个像素点的相对情况，用于建立主成分分析模型。
English Description：
Rotating machinery two-dimensional holographic spectrum calculation, data normalization model, vibration modal and DC-DC part of the constant power single loop control, uniform linear array of CRB curve, showing relative situations between two adjacent frames of each pixel for a principal component analysis (PCA) model.
