用织纤布吸附快速测定钍废水中的α放射性

本文介绍一种快速监测钍废水中放射性核素浓度的方法。该法简单,其具体步骤是将一定大小的织纤布浸泡于废水中,搅动一定时间后取出,冲洗并烘干,即可直接测量。在一小时或更短的时间内便可得到结果。实验发现4号布对钍系有选择性吸附的能力。当废水中所含放射性核素以钍系为主时,所得实验结果与放化分析结果相差大约为10%,对含有少量铀的钍废水监测下限为10~(-11)居里/升。     

酸性蛋白酶在羊毛染色前处理中的应用

羊毛纤维及羊毛织物通过酸性蛋白酶处理，可获得减量率为1％－2％，且纤维强度并未显著下降的最佳工艺条件。从扫描电镜照片发现，经处理的羊毛纤维表面磷片明显受到破坏，棱角变得圆滑。处理后羊毛织物的上染率和上染速率都有所提高。     

PETFAB: user-considerate FORTRAN 77 program for the generation and statistical evaluation of fabric diagrams

PETFAB is an easy-to-use FORTRAN 77 program which provides a comprehensive structural geologic fabric analysis package for use by geologists and students with little or no computer experience. User-selected options include a plot of data points on an equal-area stereonet, determination of data distribution and preferred orientation, calculation of statistical significance of fit, and contour diagrams using both fixed and variable counting areas. Creation of data files is simplified by use of an interactive utility loading program, LOADFAB. Output is generated on a lineprinter and optionally on a CALCOMP plotter.     

肌理作用下的建筑形态操作

An improved gray line profile method to inspect the warp–weft density of fabrics

Image processing has become a tremendous tool for various fields of applications as well as for textile manufacturing industry in recent years. Inspection of fabric density is one of the major issues for fabric manufacturers in textile industries. In this study, an image processing method comprising of linear and nonlinear techniques for automatic inspection of warp and weft yarn density of fabrics has been proposed. By avoiding common problems of linear filtering such as blurring and localization, anisotropic diffusion filtering has been applied as preprocessing operation to enhance the edge region/boundaries between adjacent yarns of the fabric images. We conjecture that given a skewed gray level image, the number of peaks in the gray line profile of the image is minimized if the image is rotated in such a way that the inter-spaces between yarns are aligned with the vertical axis. Gabor filter, an orientation-sensitive filter, is applied to the skewed image at that angle to boost the edges between inter-spaces. The number of warp and weft yarn density has been inspected by applying gray line profile method. Simulations have been done on a wide range of fabric image data set. The results have shown that nonlinear and steered filters made a contribution to the performance of the method. The number warp and weft yarn densities are determined with an accuracy rates above 90%.
