In this paper, a direct method for static voltage collapse point in rectangle coordinate is presented.
本文提出了在直角坐标系下静态电压稳定临界点的一种直接计算方法。
To do this, you first need to calculate the left-most coordinate of the rectangle, which is accomplished by the first three lines of code.
若要实现该操作，首先需要计算矩形最左边的坐标，这通过代码的前三行来实现。
Left coordinate of checker rectangle origin (upper-left corner).
棋子矩形原点(左上角)的左方向坐标。
Top coordinate of checker rectangle origin (upper-left corner).
棋子矩形原点(左上角)的上方向坐标。
The rectangle (in the coordinate system of the graphics context) in which to draw the image.
一个需要绘制的矩形区域(在图象内容的坐标系中)。
In the default coordinate system, images are situated down and to the right of the origin of the specified rectangle.
预设的坐标系中，图片从指定的矩形的右下开始。
The ellipse and the rectangle also change gradually from red to blue as the horizontal coordinate goes from 0 to 200.
当水平座标从0移到200时，椭圆形和矩形也会从红色逐渐变成蓝色。
In all cases, the upper-left coordinate of the rectangle is included in the client area, while the lower-right coordinate is excluded.
在所有情况下，矩形左上方的座标都是包含于工作区中，而右下方座标则排除在外。
Draws a rectangle specified by a coordinate pair, a width, and a height.
绘制由座标对、宽度和高度所指定的矩形。
