矩形

If you can, make a piece of black card about 4 X 5 inches with a rectangular aperture cut out of it.

如果可以的话，做了件黑色的卡与削减它矩形孔径约4× 5英寸。

Wikipedia defines a matrix as "a rectangular table of numbers or, more generally, of elements of a ring-like algebraic structure."

Wikipedia把一个矩阵定义为&一个矩形阵列，由数组成，或更一般的，由某「环」中元素组成&。

The white rectangles on a lifeline are called activations and indicate that an object is responding to a message.

HighlightsMake a tall vertical rectangle and an elongate circle; then Blend it. Duplicate it by Alt-drag to the right.

绘制一个较长的垂直矩形，以及一个拉长的椭圆，填充为深浅不同的颜色，并使用上面用过的方法混合两个图形，选中混合后的图形，移动到音符的左边，再按住Alt键的同时将其复制到右边

The equal distance 3-improved-coverage number of beacon sending position is presented according the acreage of ROI.Then a simple method is put forward to calculate the coordinates of the sending positions in rectangular ROI.Aiming at the shortage of the existent sequence algorithm,when beacon moves according to the path and emits RF signals at every position,the ant colony algorithm is applied to the position sequence so as to get the beacon sending position.Further,in this algorithm the sensors could work out their position with trilateration.

根据ROI面积给出了等距三重优化覆盖此ROI所需要的信标发射位置数量计算方法；随后对矩形ROI提出了一种简单的信标发射位置确定方法；针对现有的遍历发射位置点的路径遍历算法的不足，提出了一种新的应用蚁群算法的信标发射位置点的遍历算法，并利用该算法对基于三边测量方法进行传感器节点定位。

The rectangular group congruences on eventually orthodox semigroup were characterized by means of weak inverse and kernel-trace approach.

利用弱逆和核迹方法，刻画了毕竟纯整半群上的矩形群同余。

The split between the two groups can hardly be papered over.
