Influence of Clothing Fabrics on Skin Microcirculation

This study investigated the effects of clothing fabric on human skin microcirculation.Once skin is covered with a clothing fabric,human sensations,namely,coolness,warmth,softness,and roughness,are aroused immediately,and the cutaneous microcirculation may be changed consequently.Since the complex relationships of the human skin,the environment,and the clothing,there is few publication focusing on the physiological responses of the skin to the fabrics.In this paper,a Laser Doppler Flowmetry(LDF)was used to t...     

Compressive Behaviours of Concrete Cylinders Wrapped with 2- D Glass Fabrics

Concrete cylinders wrapped with glass fabrics of various constructions were fabricated. Compressive behaviours of cylinders with and without fabric wrapping were investigated. Comparisons of the compressive characters while using different fabrication parameters were made. It was demonstrated that the effect of the fabric reinforcement was obvious. The tensile strength of the filament used in the fabric played an important role as far as the anti-compression behaviour of the reinforced cylinders is concerned.     

TSL门工作机理分析

对ＴＳＬ门的工作机理分析提出了异议,认为在控制端ＥＮ＝１时,若数据输入端Ａ、Ｂ都为高电平,二极管Ｄ截止,这时ＴＳＬ门与普通ＴＴＬ与非门电路相同,但当数据输入端Ａ、Ｂ有低电平时,二极管Ｄ将不截止而是导通,这时ＴＳＬ门电路不能认为普通ＴＴＬ与非门电路相同。     

高精度零件配合公差的计算法

本文主要分析机械零配件的设计及高精度机械结构的公差与配合理论分析。在以往的机械设计中多是根据现有公差标准及经验数据,这在某些批量加工生产中能得到很好的应用,但在单件成产及做零配件过程中会碰到一些困难。因此,本文主要从理论的角度,采用计算方法来确定尺寸公差及形位公差并举实例说明此方法的应用。     

Research on the Geometry and Microstructure of the Coir Fiber

Coir fiber is derived from the coconut shells and considered to be an economical and natural material. In order to further extend its application fields,the geometry and microstructure of the coir fiber were thoroughly investigated in this research. The single fiber length measurement was carried out,and it was revealed that the length of the coir fiber was between 8 and 337 mm. Length distribution of the coir fiber was simulated by using the computer technology,and was found to be in coincidence with that ...     

紫外线对玻璃纤维增强复合材料力学性能的老化研究

采用扫描电镜(SEM)、差式扫描量热仪和力学测试方法,研究了紫外线对玻璃纤维增强复合材料力学性能的影响.研究表明,随着紫外线辐射时间的延长,试样的拉伸强度和冲击载荷峰值总体上呈先上升后下降趋势,但冲击性能对紫外线的敏感程度要远低于拉伸性能.通过试样的Tg变化可以证明,短期紫外线辐射会引起试样的后固化,造成Tg及力学性能的上升;而长时间的光老化降解作用会导致大分子链断裂,造成Tg和力学性能的下降.
