查询词典 incidence matrix

In many practice problems such as to know the resonnance frequency of a structure and to know the critical value for the stability of a dynamical system,often need to compute the eigenvalues of a symmetric matrix. The chief method to compute the eigenvalues of a symmetric matrix is first to transformate the matrix to a symmetric tridiagonal matrix similarly and orthogonally, then to use the QR method with shift to the symmetric tridiagonal matrix.

很多实际问题，如求结构振动的固有频率，动力系统稳定性的临界值等常常归结为计算对称矩阵的特征值，而首选的计算方法是先把该矩阵正交相似变换成一个对称三对角矩阵，再对这个对称三对角矩阵用带位移的QR方法。1968年J.H。

Results摘要: The incidence rates of renal dysfunction, shock, cardiovascular failure and gastrointestinal hemorrhage, the score of acute physiology and chronic health evaluation Ⅱ and the frequencies of pulse and breath in the severe hypoalbuminemia group were all higher than those in the mild hypoalbuminemia group (P＜0.05 or P＜0.01). The differences of incidence rate of hepatic failure and the scores of Ranson and Balthazar CT between these two groups had no statistical significance (P＞0.05). The incidence rate of infection and the mortality in the severe hypoalbuminemia group were higher than those in the mild hypoalbuminemia group (P＜0.01) in the later stage of SAP.
