次对角线

According to the above matching method of diagonal line, the worst situation is the comparison of 2*1,000*1,000 times (Notes: every team includes two figures), and the best situation is the calculation of 1,500 times. And then match each team respectively.

按照上述的对角线匹配算法匹配这两个数组的运算量最坏情形是2＊1000＊1000次比较（注意每个数组项包含两个数），最好情形是1500次运算。

So keep that left-footed player on and try the same thing again but this time, instead of taking a quick step diagonal-right, take a quick step diagonal-left and hold that direction.

因此，保持左脚球员和尝试同样的事情再次但是这一次，而是采取了迅速的一步对角线权，采取对角线快一步左和持有这一方向努力。

The characteristic vector of the real symmetric matrix should be found out, which is orthogonalized and normalized to a standard orthogonal base and is used as row vector to construct the transformation matrix P, so the P~(-1)AP can be made into diagonal matrix.

实对称矩阵A经相似变换P-1AP可化为对角矩阵，在x =Py 下，不一定能化A的二次型为标准型；应寻求对称矩阵A的特征向量，将其正交化并单位化作为标准正交基，作为列向量构造变换矩阵P，可使P-1AP=Λ为对角阵，在x =Py 下，要将二次型化为标准型，且二次项系数即为对角阵Λ主对角线上元素。

Many sources for Vanvitelli's inspiration for these surprising and dramatic vestibules have been suggested, but only Vanvitelli's first training in scenography can explain the effect of infinite space achieved by the fleeting diagonal planes across the rectangular courtyards.

为万维泰利的灵感来源，许多这些令人惊奇和戏剧性的门廊已提出，但只有万维泰利在透视画法的第一次培训可以解释的整个矩形院落稍纵即逝对角线飞机取得无限的空间效应。

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 signal s, 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。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
