14C测定判别武王克商年代范围始末

武王克商年代是我国古代编年中的一个关键点，近年来^14C测定技术有了重要发展，我国^14C测年界在此基础上探讨了^14C方法应用于商周历史纪年的希望。1996年夏商周断代工程正式立项，利用^14C测定判别武王克商年代范围的任务得以实施。1998年初两个常规^14C实验室以3‰测定精度，前后开始对陕西丰镐遗址出土样品^14C测定，并于1998年10月6－7日先后公布了^14C数据，提出武王克商代范围应判别在公元前1050－1020年间。1998年下半年AMS室开始测定。三室测定数据对比结果基本相合，利用殷墟，琉璃河等遗址出土的样品系列作^14C测定得出的结果，与上述年代范围一致。1998年11月30日公布了天计算结果，与测定结果不谋而合，经多方面反复验证，历时近二年，都无法动摇已有的判别结果，具有较高的可信度。

The whole story on distinguishing the age rang of King Wu conquered over Shang by 14C dating

The reliable year of King Wu conquered over Shang Dynasty is an important year in Chinese ancient historiography. Recently ,the technique of 14C dating has been gready improved, and the possibility of distinguishing the year of King Wu conquered over Shang Dynasty using ' C dating was discussed in conferences, some pre ~ research works performed. Since 19%,the program 'Xia~ Shang- Zhou chronology project' has put into practice,our team began to take part in the study of above chronological problems.la early 1998,the samples collected from Fenghao site,Shanxi province,China,were determined in two conventional 14C laboratories vvith the measuring error are less than 3%e. On October 6th and 7th,the results were announced succes-sively that the year of King Wu conquered over Shang Dynasty vvere distinguished in the period of B. C. 1050 to B. C. 1020. in later 1998,the AMS 14C laboratory began dating too. The results of three 14C laboratories are identically vvith each other.14C dating of the samples unearthed from tombs at Yirmi site,and Liulihe site and wiggle - matching with curve to-gether reached the results that the boundary years coincided with the year range determined above.On November 30th 1998, the result by astronomical calculations were announced, the year of King Wu conquered over Shang Dynasty located also in the age range by 14C dating. From early 1998 to March 2000,almost during two years, the age range distinguished by 14C dating had been examined many times. At last,the results would be trustworthy ac-knowledged.
