One recent afternoon at the chain's outlet in the Atlantic Terminal shopping center in Brooklyn, N.Y., pastry chef Nathaniel Sebro proudly displayed a rectangular white tray topped with three 2.5-ounce mounds of sweetness: a round strawberry cheesecake that would easily fit in the palm of Sebro's hand; a hockey-puck-size devil's food cake drizzled with cappuccino icing; and a half-scoop of Snickers Crunch ice cream perched atop an Oreo and peanut crust.

不久前的一个下午，在纽约布鲁克林Atlantic Terminal购物中心，糕点厨师Nathaniel Sebro自以为傲地展示了他的杰作，在一个白色的长方形纸盒上，放置着三个2.5盎司的迷你小甜点：一个圆形的草莓芝士蛋糕，一个冰球大小的卡布其诺蛋糕和一个半勺大小的Snickers Crunch 冰淇淋，冰淇淋上还裹有奥利奥奶油夹心巧克力饼干和花生。

The propagation of Gaussian bea ms through a paraxial ABCD optical system with hard edge aperture is studied. In the treatment the rectangular function is expanded into a sum of complex Gaussia n functions, thus the approximate analytical propagation expression can be deriv ed.

对高斯光束通过有硬边光阑近轴 ABCD光学系统的传输进行了研究，采用将矩形函数展开为复高斯函数的技巧，推导出了近似的解析传输公式。

The innovative and unique points are as follows. The method of magnetic potential self-balance is put forward applying the characteristic of iron core''s rectangular magnetization curve.
