利用图像分析法研究不同浆料配比对打印质量的影响

利用图像分析方法研究浆料配比和填料的种类对喷墨打印纸的打印质量的影响.根据油墨的渗透和扩散行为而导致的点的边缘锐化值、文字的羽化程度和点的喷墨打印质量指数等研究喷墨打印质量.研究结果表明：加填是影响喷墨打印纸打印质量的最重要因素.浆料配比对于以打印点的边缘锐化值、纸页的打印文字面积和点的喷墨打印质量指数表示的打印质量没有明显影响,但对于不加填和研磨碳酸钙加填的纸页,纸页打印点的边缘锐化值随着针叶木浆料占混合浆料的比值的增大而增加,这表明对于不加填纸,阔叶木浆有利于提高以点的边缘锐化值表示的打印效果.     

丁香酸甲酯在漆酶处理纸浆及其木素中的作用

以未漂硫酸盐浆（KP）为原料，研究纸浆经臻酶处理，以及在漆酶处理过程中添加丁香酸甲酯（MS）对纸浆湿强度的改善效果；采用凝胶渗透色谱法测定纸浆中木素分子质量及其分布的变化．研究结果表明：漆酶处理可使纸浆湿强度明显提高；添加丁香酸甲酯的漆酶处理，对纸浆湿强度的进一步提高有促进作用；漆酶和漆酶／MS处理后，浆中木素分子质量提高，木素发生缩合，是纸浆湿强度提高的原因之一．经漆酶和漆酶／MS处理后的未漂KP浆，手抄片抄造过程中，不同干燥方式对纸浆湿强度的提高和木素分子质量及其分布的影响不同．     

楚竹简札记二则

在上博简《鲍叔牙与隰朋之谏》中的"悒"一词,根据字形分析、音韵考证以及古文献查证,其应为一连绵词,表示愤恨,但是为了行文押韵,把"悒"写成"悒"的形式。另外,郭店简《唐虞之道》中,"圣"字的几个怪异形体都是因省简笔划而造成的。     

四种竹材维管束和薄壁组织的比较解剖研究

Radial Yarn Movement in Yarn Duct of Interlacer

In order to find the relations between the production performonce of interlacer and its cross-sectional Shapcs of yarn duct,radial yarnsd movement in varions yarn ducts of interlacer and its effect on performance of interlaced yarn were studied in this paper. Seven interlacers,which were diffcrent in the cross- sectional shape of yarn duct,were made. Yarn motion in yarn duct of interlace was observed with optical fibers and photo- sensors. Performance of the interlaced yarn was evaluated by the number and the strength of tangles. Experfmental results disclose the relations between the yarn motions and the properties of the interlaced yarn. The interlacer with round yarn duct is capable of producing an interlaced yarn with bigger number of tangles,since It can make yarn transverse frequently the axis of air jet issuing from air jet nozzle. The interlacer with cornered shape of yarn duct makes yarn subjected to the action of compressed air for a longer time,which results in larger strength of tangles.     

Study on Wet Permeability Models of Yarns and Knitted Fabrics

Water transport through the pore structure of the knitted fabric can occur only in place where the fiber-water surface attraction force is greater than the water weight in the capillary. To investigate wet permeability of the knitted yarn in the fabric, a liquid transport model is established. The main factors which have significant influences on the liquid transport have been analyzed. It is derived from the argument that the optimal design for the knitted fabric with quick sweat transport property can be obtained.
