The pigments used by the ancient Egyptians constitute the most diverse pigment palette of the ancient world. This review discusses the pigments and binders which were used, arranged principally in terms of the colours themselves, namely, the white, green, grey, black, brown, blue, red, orange, and yellow pigments. The chemical identity of these pigments is discussed with some details regarding the artefacts or time periods from which the pigment concerned has been identified. Combinations of pigments were used for creating some colours, especially: greens, pinks, blues, yellows, and a variety of pale hues by mixing primary colours with a white addition, such as calcite. The identification of ancient Egyptian pigments is often aggravated by chemical interactions between pigment and binder media, or between the pigment and environmental pollutants, or both. The nature of the binders and varnishes used in ancient Egypt is briefly discussed. The identification of green pigments from ancient Egypt is often difficult, and some of the recent research concerning the topic is reviewed. In addition to including relevant details from older literature, this review provides a synopsis of recent studies which have appeared since the last major review carried out by Lee and Quirke in 2000. 相似文献

翻译是把一种语言所表达的意义用另一种语言表达出来。但翻译不仅是语言转换,还要体现其美学功能。本文试以化妆品、科技和电影片名为例,谈谈实用文体翻译中的美学。 相似文献

商标的翻译过程不受句子、段落、篇章等较深语言层次的影响。然而,由于功能上的特殊要求,牌名的翻译在一定程度上也表现出复杂的现象,也需要运用翻译理论和原则加以指导。可以说在一切翻译理论中等效原则,最适用于牌名翻译的方方面面。在等效原则的指导下,通过直译法,音译法,意译法等方法来提高品牌名称翻译的质量,增强译名的可读性。 相似文献

硒是化妆品中的限用物质。应用氢化物发生-原子荧光光谱法测定化妆品中痕量的硒,样品用硝酸和高氯酸消解,盐酸可以使硒（Ⅵ）还原成硒（Ⅳ）,硒（Ⅳ）与硼氢化钾反应产生硒化氢,硒化氢被带到原子化器,在最佳的条件下用原子荧光检测。这种方法测定化妆品中的硒,样品处理简单快速,方法的线性范围宽（0—20μg/L）,基体干扰少,检出限低（0.081μg/L）,加标回收率在96.05%—101.96%之间,相对标准偏差2.74%—2.99%。 相似文献

目的:建立反相高效液相色谱法同时测定化妆品中的4种雌激素(雌酮、雌三醇、炔雌醇、己烯雌酚)的方法。方法:色谱柱Inertsil ODS-C18(4.6 mm×250 mm,5μm),流动相为甲醇-水(体积比为60:40),流速1mL/min,检测波长279nm,柱温:25℃。结果:4种雌激素成分在0.05～500μg/mL浓度范围内与其对应分峰面积线性关系良好。样品的平均加标回收率为97.3%～110.6%,RSD为2.9%～4.0%,化妆品中四种雌激素的检出限为0.02～0.03mg/kg。该方法操作简便、灵敏度高,能够同时检测化妆品中4种雌性激素的含量。 相似文献
