0 A diagonal line is straight and sloping, not horizontal or vertical, for example joining two opposite corners of a square or other flat shape with four sides. -- 斜线的，对角线的
1 a straight line that joins two opposite corners of a four-sided flat shape, such as a square -- 对角线
He was wearing a sweater with a diagonal white stripe on the front.
Each contains three non-zero diagonals in block structure as shown in figure 17.
Total genetic and environmental variances (squared and i100) are on the diagonals in bold.
Similarly, the number of points can be further increased by successively considering diagonals of different parallelograms as the reference line.
They are placed over the model diagonals to exploit frequent symmetries in the objects used as landmarks.
By scaling the diagonals of rectangles to a common length ab, the locus of vertices of the rectangles is obtained as a circle of diameter ab.
Then it is one of the attractive features of the cell-vertex method in two dimensions that only the components of the quadrilateral diagonals appear in the residual.
