The Honey Bee In New Spain and Mexico

Resort-hotel location has diffused from the Northeast and Midwest to the Sunbelt and West. In 1985 there were approximately 834 resort hotels and 295,617 resort-hotel rooms in the United States. More than half of these rooms were located in just three states: Florida, Nevada, and Hawaii. The present distribution of resort-hotel rooms has been influenced by three periods in resort-hotel evolution. Until the early 20th century, resort hotels were in the tradition of the “Grand Hotel,” oriented toward natural resources in the East and Midwest and serving an elite clientele. Later in this period, elite resorts were also developed in the coastal Southeast and in the Southwest. A second, transitional period beginning in the 1920s accelerated construction of resort hotels in the Southwest and along the Southeastern coast. In the third period, post World War II mobility and affluence led to a revolution in resorthotel location and function. Resort hotels are now found in urban and suburban locations and have expanded the resort concept by linking it to meetings, conventions, and business travel. This has allowed resort hotels to adapt to changing market conditions and to achieve economies of scale by spreading demand throughout the year.     

传世纺织品文物除尘方法研究——以湖蓝色缎绣凤纹大卧单为例

传世纺织品文物表面蒙尘、污染是一种较为普遍的病害。除尘成为了传世纺织品文物保护修复过程中极为重要的一环。针对不同状态的文物,如何安全、有效、便捷地进行除尘工作成了本研究的方向。本工作主要研究原陈设于养心殿体顺堂的湖蓝色缎绣凤纹大卧单的除尘方法。首先,对现有传世纺织品文物的物理除尘方法进行归纳,总结为5种类型：吸尘法、擦拭法、震动法、粘附法和凝胶法。其次,对该文物进行全面研究,包括制作工艺、图案样式、病害分析、试验检测等。研究结果为：该文物是双层罩面罩里加四周缝网穗制作,面主要为绒线绣、捻线绣花鸟纹;黄色绣线出现合成染料酸性偶氮染料,推测可能是19世纪末至20世纪初生产;绣线纤维强度较好,绣底局部糟朽,具备一定除尘条件。再次,通过除尘实验对比博物馆专用吸尘器、真空负压液态过滤除尘设备、超细纤维布作用文物的除尘效果。实验结果确定除尘方法为：首先用博物馆专用吸尘器进行第一遍的初步除尘,然后用真空负压液态过滤除尘设备进行第二遍的精细除尘。最后,结合文物织造、刺绣的工艺特点,将文物局部特征分类为：缎底、缎面开裂、压瓣、出边、水路、绒线绣线、加捻绣线、打籽绣,并研究分析针对它们的除尘手法。相比以往...     

河南博物院展室空调滤网吸附灰尘的分析

博物馆环境中的粉尘对文物有不利的影响,需了解其成分和来源,为文物的保存环境的选择提供科学的数据。为此,采用红外光谱、X射线衍射、扫描电镜等手段对河南博物院空调滤网上的粉尘进行了成分分析和形貌分析。分析结果显示,粉尘包括无机的硅酸盐物质和各种纤维。分析结果说明,博物馆展室这样的人工环境中仍然含有对文物有危害的因素,而空调措施对去除粉尘具有一定的作用。     

三门峡庙底沟M254出土瓷器年代商榷

《三门峡庙底沟唐宋墓葬》公布了M254出土的一件青瓷钵,关于该钵的年代似有可商榷之处。本文在原报告基础之上对其年代进行再探讨,认为其相对年代为金元时期,而非报告中公布的唐代。同时,推测其生产窑口可能是汝州东沟窑。     

安徽当涂东晋墓发掘简报--兼论出土的玻璃碗残片类别和来源

当涂东晋墓的发掘,除出土了东晋墓中常见的青瓷器外,最大收获是发现了4片玻璃碗残片,经检测定性分析,它与当时国产玻璃成分不同,与湖北鄂城西晋墓出土的玻璃碗成分相似,同为舶来品萨珊玻璃器。它的发现为六朝时期中国南方与西方国家进行商品贸易方面的研究提供了实物资料。
