diagonal elements meaning in English

对角元素

We showed that a determinant in diagonal form is equal to the product of the diagonal elements .
我们已证明一对角形行列式等于其对角元素的乘积。
The algorithms estimate the doa of the broadband distributed source fron the secondary diagonal elements of the covariance matrices generated from every frequency domain of the received broadband signals , thus avoiding unwrapping of phases
该类算法首先将阵列接收的宽带信号变换到频率域，然后对于每个频率形成阵列接收信号协方差阵，最后由该协方差阵的次对角线元素估计宽带分布源的到达角，其主要特点是避免了相位展开。
Have been suggested . given a contingency table whose cells are numbers of parents who either do or not transmit the associated marker alleles to affected children , t compares every symmetric pairs , both tn and t compare row and column total for every marker allele . tm uses all cells but t uses non - diagonal elements only
给定一个列联表(其元素为传递或未传递某种等位基因给生病小孩的父母的个数) ， tc比较列联表的每一个对称的部分， tm和tmhet均比较其相应的行和与列和，但tm用到了表中所有的元素，而tmhet只用了非对角元素。
