To compute moments of a twodimensional image, a large number of multiplications and additions are required in a direct approach.

它的基本思想是利用数据并行性将一个二维图像矩分解成垂直矩和水平矩，然后在LS MPP协处理器上利用级联求和算法在垂直方向和水平方向分别计算二维图象的多个垂直矩和一个水平矩。

In the design of W band double-balanced mixer, a novel structure using Magic-T and two baluns, which all realized by ratrace, is proposed with no crossing of transmission line.

在W频段双平衡混频器的设计中，本文提出由混合环构成的魔T与巴伦级连而成的功率混合电路，这种新颖的电路结构使整个电路单平面化，避免了任何跳线。
