木地板市场良莠不齐

广州市消委会人员以消费者身份在市场上随机购买了12个品牌的角香茶茱萸(市场名为芸香)地板块、绿心葳(市场称为紫檀)地板块等木种,委托广州市出入境检验检疫局进行检测。检测试验的样品为实木榫接地板块。 检测结果显示: 一、尺寸指标分析:多数品牌的外形构造尺寸偏差超出极限偏差甚远: 二、含水率指标分析:有35种木种符合标准,有6种桦木(市场名为枫木)地板块含水率不符合要求;

A Novel Angular Furanocoumarin Isolated from Cnidium monnieri Fruit

唐方宋谱:释“衙香”

经由考察“牙香”与“衙香”在历代香谱中的内涵,以及唐宋时期“牙”与“衙”字义的流变,并借助唐、宋、明各时期文献中“牙香”与“衙香”的使用情况以及相关民俗学资料,可以推断,作为合香方的“牙香法”最晚出现于唐。缘于“牙”“衙”在唐代之后语义上的讹变,“牙香”渐被统改为“衙香”。明代文献中经常出现的“牙香”为当时流行的沉香生料“角香”别名,与唐宋时期的“牙香”无关。现代权威辞典专书中不仅均将“衙香”混淆于“角香”,时或弄错了“衙香”“牙香”历史出现的先后次序。
