考古学诞生两百年来,已经被人们公认为研究古代社会重要的科学方法。报刊上时有考古新发现的报道:诸如发掘海底一千五百年前的沉船,山洞里一万年前动物的化石,地下一千七百五十年的坟墓出土等等。很多人奇怪,长沙马王堆出土的棺椁根据文物就可以判定是汉代轪候夫人的坟墓;那么,这许多无名氏沉船、化石、坟墓的年代又是怎么断定的,竟然说得这样准确?这就是奇妙的放射性同位素给人类立下的功勋,它的发现和应用也是科学发展史上重要的一页。
Archeology has been recognized for two centuries as an important scientific method of studying ancient society. Newly reported archeology in the press, such as the discovery of the wreck of the seabed 1500 years ago, the fossils of animals 10,000 years ago in the cave, the excavations of the 1750-year-old underground tombs and so on. Many people find it strange that the coffin unearthed from the Mawangdui in Changsha can be judged as the tomb of the lady of the Han dynasty according to the cultural relics; then, how many anonymous shipwrecks, fossils and tombs are dating? The miraculous radioisotopes make meritorious contributions to mankind. Its discovery and application are also an important page in the history of scientific development.
