In the matching phrase normalized distance and Mahalanobis distance are used to identify the view class and build the affine matrix. 匹配阶段分别采用归一化距离和马氏距离作为视类判定和仿射矩阵建立的依据。
However,it is not necessary to expand this matrix since there is no singularity problem for viscoelastic frames due to visco-damping. 文章将应用于弹性杆系结构动态响应的回传波射矩阵法扩展应用于粘弹性框架的瞬态问题的求解。
