Stop Down: To decrease the diameter of the light-admitting orifice of a lens by adjustment of an iris diaphragm.

缩小光圈：镜头的焦距和光圈的有效直径之间的关系。一可调节的彩虹光阑，减少透镜光孔的直径。

This structure can decrease spherical aberration coefficients, and improve the convergence of three beams without deteriorating of the focusing performance.

分析表明这种结构减小了透镜像差，并且解决了缩小束间距引起的球差系数和放大率上升的问题。

Plus lenses magnify and minus lenses minify.

正透镜可以放大，负透镜可以缩小。

We use Welford's aberration equation to obtain the initial phase parameters of the diffractive surface of the designed hybrid achromatic lens.

复合透镜不同於传统折射透镜，它一面为传统折射透镜，另一面为绕射透镜；它不但可消色差及降低其他像差，在体积及重量的缩小上也有相当的成效。

The original technology is based on the far-field optical but all of them are restricted by Rayleigh diffraction limit.In order to break optical diffraction limit restrictions, people improve recording density in three ways:(1) shorten wavelength of light,(2)increase numerical aperture of the lens N.A.

不过上述储存方式所采用的记录技术皆是在远场光学的领域内，在远场光学的绕射极限下，要持续提升记录密度的方法有三种；(1)缩小光源波长(2)提高透镜的数值孔径

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
