This method also allow us to select the most efficient way from the bulk optical systems and available recoding methods, i.e., identifying the space bandwidth product of the input signal, the minimum size of lens apertures, the sample space and total sample number of CCD and spatial light modulator, the need of magnification before the signal passes through a SLM or when the signal reaches the camera.

通过该方法可以确定合适的加密系统和光学器件，例如输入信号的空间带宽积、变换透镜的最小孔径、空间光调制器的分辨率和像素大小、CCD的分辨率和像素大小以及入射到空间光调制器和CCD靶面上光场所需的放大倍数。

The results shows that the effect of the speckle noise can be suppressed by displaying OCT images in the logarithmic scale and the speckle properties are correlated with the scattering properties of the tested sample. Additionally, it is shown that OCT with NA = 0.25 has a lower speckle noise and a larger length of single scattering range.

结果显示采用对数表示可以抑制散斑噪声对图像对比度的影响，而且此时的散斑特性与介质的散射特性相关联，另外，采用较高数值孔径显微物镜可以抑制散斑噪声以及增大成像深度。

It is found that, compared with the vacuum sintering, the magnet sintering at argon protection has lower density, magnetic-energy product and remanence, but coerciveforces are higher. The magnet has more and bigger pores, and there obviously exist loose microstructure, the Nd-rich phases are clearly distributed along the grain boundaries mainly in the shape of lumpish and lamelliform.

研究发现，与真空烧结相比，采用Ar保护烧结时磁体的密度、磁能积和剩磁相对较低，矫顽力较高，磁体中形成的孔洞较多，孔径较大，并有明显的显微缩松存在，富Nd相的数量明显较多，且主要呈块状和片状沿晶界分布。

Because printed circuit board is developing in the direction of fine line, high density, small aperture and multiplied layers, apart from that the requirement for inner and outer quality of base material is extremely high, more and more rigorous requirements are proposed on manufacturing environment and lustration of process.

针对 PCB 向细线路、高密度、小孔径、多层化的方向发展、除对其基材的内外质量要求极高外，也对制造环境和制程的洁净度提出越来越苛刻的条件。
