纺织物指别词语的翻译特色

运用简单的集合原理研究了纺织物指别词汇的语义场,发现其中的上下义关系的类属指别词和多项分类对立关系的种属指别词可以用9种不同的翻译策略加以翻译,其中的部分语义重叠特征的同义聚合关系可以构成纺织物指别词翻译的一词多译维度.另外,归纳了9类与纺织物指别词相关的修饰性范畴词,共同构建了纺织物指别词翻译的能产性网络,用于翻译纺织物的基本指别词汇.     

上海城市生活垃圾的组成及热值分析

对上海城市生活垃圾的组成、燃烧特性、元素分析及热值等试验结果的分析表明:粒径为40～120 mm的垃圾含量最大,试验的平均质量分数约为43.5%;其次是粒径为8～40 mm的垃圾,平均质量分数约为34.9%;粒径大于120 mm的约为15.7%,小于8 mm的约为5.8%.有机物质量分数高,约占65%,且含水率高,热值低,不适合焚烧;可燃物(塑料、纸类、纺织物、包装物、木块)质量分数约为30%,含水率较低,热值高,适合焚烧.由此说明,上海城市生活垃圾的处理不宜采用单一的方式,必须综合处理以利于垃圾资源化.

棉/ZIF-67衍生的复合材料用于处理含双酚A废水

以廉价的废弃棉(Cotton)为载体负载一种金属有机框架(MOFs)材料ZIF-67,通过高温煅烧制备出钴/棉碳(Cotton/ZIF-67-700)复合材料.采用X-射线衍射、扫描电子显微镜、透射电子显微镜和X-射线光电子能谱等手段对材料进行表征.将Cotton/ZIF-67-700材料应用于催化活化过一硫酸盐(PMS)降解水中的双酚A(BPA),评价其性能及各种影响因素.通过淬灭实验和电子顺磁共振(EPR)波谱识别催化反应体系中产生的活性氧(ROS)物种并推测反应机理.结果表明：Cotton/ZIF-67-700对BPA具有优异的吸附性能，理论最大吸附量达到227.1 mg/g; Cotton/ZIF-67-700可在宽的pH范围(3～11)高效活化PMS降解BPA,且能循环使用多次；淬灭实验和EPR波谱分析证实，硫酸根自由基(SO₄^·-)、羟基自由基(·OH)和单线态氧(¹O₂)为主要ROS参与BPA的氧化降解.本研究提供了一种廉价和规模化制备MOFs衍生金属/碳复合材料的通用策略，展示出该复...     

Combustion Properties of Textiles Applied in Tibet Ancient Buildings Designs and Their Clean Flame Retarding

In the Tibet ancient buildings, there are large amounts of combustible decorative textiles that pose great potential fire hazards. Some typical textile samples were collected from the Potala Palace. Their combustion properties were analyzed by UL 94 Vertical Burning test and Limiting Oxygen Index test. The effects of plateau climate on combustion properties, an important fact required to be considered in the flame retarding design for combustible textiles, were preliminarily compared via test data in the plain and those in the plateau. Based on the foregoing analyses, some thoughts were presented on the clean and feasible flame retarding means for the decorative textiles due to their special applications in Tibet, in ancient buildings and in plateau climate. The fire resistance, weather resistance, UV resistance, endurance, ornamentation and religious performances for these textiles must be taken into considerations comprehensively in the designs.
