阿马尔那泥板书信中所见的古代近东大国外交方式

阿马尔那时代是近东历史上的和平外交时代，五大国支配着外交的走向和国际关系的格局。在大国外交中，存在3种外交方式，礼物交换、王室联姻和信息沟通，这3种外交方式构成了当时外交的主要形式，促进了和平外交的持续发展。     

The evolution of maritime Chinese historiography in the United States: toward a transnational and interdisciplinary approach

ABSTRACT

Once considered a marginal side-story to the Fairbank-inspired narrative of an agrarian-centered, land-bound China, Chinese maritime history has received increasing attention in the United States as a research field in its own right. Through sustained engagement with trends in regional, comparative, military, and global histories, and dialogue with European and Asian academia, the efforts of several generations of scholars after Fairbank have slowly broken down his paradigm. Studies of maritime China are increasingly showing a broad, integrated maritime East Asian region comprising the seas and their littoral from the Sea of Japan to the Strait of Melaka. This article surveys the historiographical development of the field. It also highlights my work-in-progress on autonomous overseas Chinese polities along the Gulf of Siam littoral in mainland Southeast Asia during the eighteenth century as one possible future path for the study of maritime Chinese history.     

明益王“秋波”琴的漆涂层材料与工艺分析

孙中山故居纪念馆馆藏一张明代落霞式古琴“秋波”,据考证为明代受封于江西抚州的益王监制。清代以后,它被广东的文人琴士评为广东四大名琴之一。运用剖面显微观察、扫描电镜能谱分析、显微拉曼、光学光热红外显微光谱、热裂解-色谱质谱分析等科学检测手段,对古琴脱落的大漆残片进行了无机和有机成分分析,并对其工艺进行了讨论。实验结果表明,大漆残片保存了两个时期的不同髹漆工艺,早期以蛋白质类和非/半干性油黏结剂混合黏土类无机矿物做灰胎,晚期以大漆和干性油黏结剂混合鹿角霜/骨灰做灰胎并掺加少量黄铜屑。将科学分析与古琴槽腹、琴背的铭文相印证,进一步明确了“秋波”琴明末斫髹、清末修复的流传历史。此外,运用盖蒂保护中心研发的ESCAPE数据分析方法,首次在中国传世古琴样品中明确鉴定出一般认为产自越南的野漆品种laccol,其为清代重修时广东中山的修琴师使用添加的。本研究立足于古琴文物实体,以详尽的科学实验为支撑,并参阅《太古遗音》《髹饰录》等文献,为明代益王琴的制作工艺提供了参考,同时为古琴文物的保护修复提供了科学支撑。
