1786年赴粤的“大土耳其”号，是继美国“中国皇后”号来华的第三艘商船。“大土耳其”号来华并非预期的计划，而是在“中国皇后”号的激发以及英国钳制贸易的格局下，美国海商由好望角向印度及东南亚转向促成的贸易事件。本文挖掘中外文档案文献，考察了“大土耳其”号广州贸易情形，并对某些记述及历史遗留物进行了辨正。

The first "Grand Turk”coming to Guangzhou in 1786 was the third American merchant ship after the   "Empress of China.”Its trade plan was not planned，but inspired by the success of "Empress of China”and brought about by American merchants’trade transformation from Cape of Good  Hope to India and Southeast Asia when Britain clamped maritime trade on new-born America. Through mutual corroboration of Chinese and English archives and documents this article explores "Grand Turk”’s trading situation in Guangzhou，and does a textual criticism and correction nn historical records and relics of the past.
