记叙文写作中的语言描写

从某种意义上说，学习写作本质上就是学习用书面语言表情达意，就是培养学生的语言能力。俗话说，言为心声。这句话告诉我们：生活的积累、情感的酝酿、知识的储备、思想的砥砺，是语言的内核，是语言的根底，是言语活动的原动力。如果一味地以语言加工语言，其结果必然形成学生作文语言的“软骨症”。因此，记叙文写作中的语言描写必须根植于生活、融合于情感、繁衍于知识、锤炼于思想。     

庄子与尼采理想道德人格思想之比较

庄子与尼采二人的学说有很多相似之处，然而，二人学说的思想内容又迥然不同：从理想道德人格的角度来比较，他们思想的异同主要体现在理想道德人格的基础、理想道德人格的特征、理想道德人格的修养等方面.

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.     

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.     

Research on Properties of Woven Fabrics Treated by High Pressure Water Jet

The paper introduces a new technique for the treatment of the woven fabrics. Sprayed by high pressure water jet, the appearance, handle and stiffness of the fabric are improved. Other properties of the high pressure water treated fabrics like drape coefficient, air permeability, tenacity are also presented.     

Tensile Behavior of the Flax/Polyester Composites after Water Treatment

With flax fabric as the reinforcement and unsaturated polyester as the matrix,composites of two,three,and four layers were fabricated respectively by the vacuum assisted resin infusion(VARI)technique.Tensile strength of the composites after being saturated in the water for different durations was tested.The tensile strength of the two-layer composites was decreased after being soaked in the water for two,three,and six month,respectively.For the three and four layers specimens,the tensile strength was decrea...
