水电站压力钢管或蜗壳外敷设的薄垫层,可以定量调节钢板和外围混凝土所分担的内水压力比例。目前,解析推导内压传递系数计算公式时尚未涉及垫层材料的非线性。本文基于多层圆筒理论和垫层的受力特点,尝试推导了考虑垫层材料的压缩非线性,以及垫层、钢管和混凝土之间存在间隙的内水压力传递系数λ的解析解。结果表明,垫层作为非线性材料,λ的大小受间隙、作用内水压力、垫层的厚度、残余应变及当前循环加载阶段的应力-应变关系的影响。算例表明,λ随垫层初始厚度变薄而增大,即垫层越薄,传递的内水压力越大。此外,λ随循环加-卸载次数的增加而逐渐减小,但当循环次数达到某一数值后,λ基本不再变化。

The pyrolysis characteristics of PVC were systematically investigated using a Netzschne TG thermo-balance coupled to a quadrupole mass spectrometer. The pyrolysis conditions were 0.1 MPa of Ar, a heating rate of 10 ℃/min and a final temperature of 1000℃. Both the thermogravimetric properties and the simultaneous evolution of gaseous products during pyrolysis were studied. The TG/DTG results showed that as the pyrolysis temperature increases the weight loss and weight loss rate of PVC increases. Near 412℃ the weight loss rate attained its peak value. At higher temperatures the rate of loss gradually decreases. The gases evolved during thermogravimetric analysis were analyzed by a mass spectrometer, monitoring the relative intensity of HC1, C6H6, light hydrocarbon and chlorine-containing gases The evolution curves showed that HC1, C6H6, light hydrocarbon and chlorine-containing gases all peak at about 416℃. This is consistent with the fact that the weight loss curves also peak at about 412℃. The extensive HCl evolution is consistent with the high chlorine content of PVC. The formation of these gases can be explained by considering these reactions： dehydrochlorination, intramolecular cyclization and the addition of HCl to unsaturated hydrocarbons.

在“一带一路”背景下,作为少数民族织锦典型代表的壮侗民族织锦,也获得前所未有的发展机遇。文章采用了实地调研、文献查阅及比较分析的研究方法,对两者进行横向比较分析。研究表明,壮侗民族织锦由于语言相似、地域相连等特点,织锦在图案纹理选用、构图方式组成、织造技艺流程等方面都体现了相互融合发展的特点,但由于民族文化的独立性,在图案用色、纹样内涵等方面存在差异。这一研究成果有助于为“一带一路”背景下不同国家、区域间相似民族文化融合创新设计提供参考依据。

This paper focuses on using language chunks in college English writing. Based on the psychological theory of memory mechanism, the linguistic theory of lexical approach, together with the analysis of students＇ compositions, the author argues that writing through language chunks is effective and practicable. Methods in implementing language chunks in writing are provided as an important part in this paper.
