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：
Calculated two-dimensional holospectrum in rotating machinery, normalized data models, modes of vibration, DC-DC converter using power single-loop control, Ula CRB curve shows two images of each pixel, and principal component analysis was used to build the model.
