The generalized inverse of partitioned matrices and the expression of generalized inverse using maximal nonsingular submatrix are discussed. 摘要讨论了分块矩阵的广义逆，以及用矩阵的满秩子块表示广义逆。
The submatrix method makes the definition of mistuning parameters more freely and adds the model modification function to this identification method. 采用子矩阵型技术使得失谐参数定义更加的自由，并使得该方法具有模型修正的功能；
Also we proved that any proper subalgebra of a standardKac-Moody algebra g(A) is standard, where A1 is any principle submatrix of A (see Theorem 2.6). 证明了典范Kac-Moody代数g(A)的任一真子代数g(A_1)也是典范的，此处A_1是A的任一主子阵(定理2.;6)。
Unlike Algorithm Apriori our algorithm constructlarge unit submatrix in whole matrix (under certain condition construct maximum unitsubmatrix) and avoid complex process calculating candidate itemset. 这些算法不同于Apriori算法，它们从关注矩阵M满足某种性质的行出发，迭代构造较大全1子阵（在一定条件下能得出最大全1子阵），避开了求候选项目集的复杂过程，使算法成为有效算法。
In the article in view of the phased-array radar, after introduced the submatrix adapter and the processor adapter as well as the multi -channel signal different way transmission time delay design specifically. 针对相控阵雷达，具体介绍了子阵适配器和处理机适配器以及多路信号不同路径传输后的延时设计。
