KNIT FABRIC SURFACE PROPERTY AND MOISTURE TRANSFER

This paper deals with the properties of the fabric such as surface compression energy, the thick,ness, surface hairness, compressional resilience and effect of these factors on the moisture transport.In the course of the present investigation, the possibility of expressing the relationship between thethickness and the pressure as a hyperbolic function is considered, and compressional resilience is al-so described by relative compression energy loss. The vapor resistance of fabric in terms of still air layer and mathematical model of vaportranspiration are elucidated and ten samples from various double knit fabrics made on the same ma-chine are tested in this study and a multivariate linear regression model is suggested. It is found thatthe thickness of fabric is the strongest factor in the mathematical model of vapor evaporation.     

40Cr钢离子注入后表面形态变化初探

本文对40Cr钢详细测量、分析了其二维和三维的表面粗糙度,随注入能量和剂量不同各评定参数的变化趋势也不同.离子注入使粗糙度高度参数值普遍下降,间距参数值有时增大,有时减小,通过溅射作用有时使糙峰数减少,有时又产生新峰;形状参数上峰态也发生变化.对不同参数的注入表面尚进行了自相关函数和功率谱函数分析.     

Non-Linear Characterization of the Acousto-Optic Modulator of the Preexcited-Q-Switch and Mode Locked Nd~(+3): YAG Laser

One of the main parts of the pre-laser Q-switched active mode locked Nd~3: YAG laser is the acousto-optic modulator. Therefore it is an important subject to studg the nonlinear properties of the modulator for obtaining steady state mode locking. The result of our study is presented in this paper.

Accelerated carbonation and leaching behavior of the slag from iron and steel making industry

Ground granulated blast furnace slag(GGBFS)and steelmaking slag have been used as a raw material for cement production or as an aggregate to make concrete,which contribute aluminum,calcium,iron,and silicon oxides.The suitability of the slag for a particular application depends on its reactivity,cost,availability,and its influence on the properties of the resulting concrete.For the interest of durability studying of concrete in the presence of slag,the accelerated carbonation products and leaching behavior of the slag and Portland cement(PC)were studied.The experimental results confirmed that the slag was more resistant to carbonation compared to PC.The carbonation degree of GGBFS reduced by 17.74%;and the carbonation degrees of steelmaking slags reduced by 9.51%-11.94%.Carbonation neutralized the alkaline nature of the hydrated pastes and gave rise to the redox potential of the leachate slightly(30-77 mV).The carbonation also increased the release of most of the elements presented,except for calcium,to the aqueous environment.It is concluded that blend cements(PC plus slag)have economical advantages and better durability compared to PC.     

Effect of Ecotype Carrier for Disperse Dye on Dyeing of Polyester Microfiber

Body Fuzzy Pattern Recognition in Woman Basic Block Design

Basic block is the foundation of clothing construction design because it is the media between body and clothes and the fitness of clothes should be based on the accuracy of basic block. That needs us to recognize body not to record it. This paper reports the Algorithm of woman body fuzzy pattern recognition. It is organized in three sections: (i) extracting woman body feature; (ii) establishing membership functions of feature indexes; (iii) presenting an Algorithm for woman body fuzzy pattern recognition by example.
