查询词典 resolution of singularities

Three important conclusions are achieved: 1 By analyzing the demand for spatial resolution of recording medium in different digital holographic recording setups, it shows that lensless Fourier transform holography can relax the requirement of spatial resolution and use the full spatial bandwidth of the CCD sensor. 2 Because of the differences of spatial resolution of image planes in different directions, reconstructed images can be relatively extended in the direction of high spatial resolution and reduced in the direction of the low one. 3 Lateral resolution of the reconstructed images is mainly determined by the highest spatial frequency of digital holograms recorded by CCD, and increases with the larger CCD size, the higher spatial resolution of the CCD sensor, and the shorter recording distance.

通过分析几种不同数字全息记录光路对记录介质空间分辨率的要求表明，无透镜傅里叶变换全息光路对CCD的空间分辨率要求最低，最能充分利用CCD的带宽；再现像面的空间分辨率在不同方向上的不一致，会导致再现像在空间分辨率高的方向上相对展宽，而在空间分辨率低的方向上相对压缩；再现像的横向分辨率主要由CCD所能记录的物体的最高空间频率决定，它随CCD的尺寸和空间分辨率的提高及记录距离D的减小而提高。

When we are designing a webpage, sure meeting considers the issue of resolution, science and technology develops what we use normally now is the resolution of 1024*768 and 800*600, now the width that is used to 778 to resemble element is more very on the network, often make whole webpage very depressive below the resolution of 800, have kind of airtight feeling, actually this width is the widest width that points to the webpage on the resolution in 800*600, do not represent optimal visual sense, might as well the elephantine element that tries 760~770, no matter be in 1024 still can achieve below the resolution of 800 relatively the visual effect of beautiful.

我们在设计网页的时候必定会考虑到分辨率的问题，科技发展到现在我们通常用的是1024*768和800*600的分辨率，现在网络上很多都是用到778个象素的宽度，在800的分辨率下面往往使整个网页很压抑，有种不透气的感觉，其实这个宽度是指在800*600的分辨率上网页的最宽宽度，不代表最佳视觉，不妨试试760~770的象素，不管在1024还是800的分辨率下都可以达到较佳的视觉效果。
