This can be extended to nxn tridiagonal matrix with l , u bidiagonal 把它推广到nxn三对角线矩阵使具有两对角线的矩阵l 、 u 。
Lwd : long way of design measured from center of bond to center of bond 长节距：从节点中心到节点中心的长的菱形对角线的长度。
Swd : short way of design measured from center of bond to center of bond 短节距：从节点中心到节点中心的短的菱形对角线的长度。
Subdivide the diagonal section at the back - left side of the triangle with one diagonal - back parting 在和对角线的-背面的三角形的背面留下的边细分对角线的区段离别的。
The distance between the eyes and the tv screen should be at least 6 times the screen s diagonal length 看电视时要保持室内光线充足，电视机与眼睛的距离最少应为萤光幕对角线的六倍。
Test code for machines tools - part 6 : determination of positioning accuracy on body and face diagonals digital displacement tests 机床试验规程.第6部分:体和面对角线的定位准确度的测定
Stiff quads - for quad faces , the diagonal edges are used as springs . this prevents quad faces from collapsing completely 硬四边-为四边面,对角线的边被作为弹簧。这防止四边面完全地崩溃。
Watch tv under good lighting . the distance between the eyes and the tv screen should be at least 6 times the screen s diagonal length 看电视时要保持室内光线充足，电视机与眼睛的距离最少应为萤光幕对角线的六倍。
The server stands behind his own baseline , to one side of the center mark , and then hits the ball over the net into whichever service court is diagonally opposite 发球者站在自己场地底线中间标志一边的后面，把球击到球网对面同自己所处位置成对角线的那个接发球区。
In this paper it is shown that a partial toeplitz pattern has a toeplize positive definite completion if and only if the diagonals for the specified entries are 0 , t , 2t , . . . , pt ( in which the main diagonal is numbered 0 ) 本文讨论部分toeplitz正定阵的toeplitz正定完成问题，证明了一个部分正定toeplitz模式存在正定toeplitz完成的充分必要条件是已知元所在对角线的标号成等差数列。
