We propose a novel scheme to form a 2D surface array of optical micro-traps of cold atoms by using two sets of far red-detuned evanescent wave interference and a blue-detuned evanescent wave.

提出了一种采用两套超大红失谐消逝波干涉和一束蓝失谐消逝波光场来实现原子二维表面微光阱阵列和原子有效强度梯度冷却的新方案，得到了二维表面微光阱阵列的光强分布和光学势分布。

The walls are lined with bulky green and silver machinery, an array of knobs with buttons and switches covering every metallic surface.

The electronic nose is an array of nano-scale gas sensors--the maximized surface area of the nano-particles allows the most gas to pass over them--along with pattern recognition technology that can create a digital fingerprint (or noseprint, as the case may be) of specific smells.

The array itself is a steel hoop around 20 inches in diameter, the surface of its aperture teeming with rectangular rods.
