考古是时间的科学，通常考古学家要依靠地层学和类型学判断相对年代。这种断代方法对考古学作出过重要贡献，至今仍然是很有用的。但它的局限性和不完善性是显而易见的，它无法判断绝对年代。科技测年技术引进考古学，或与考古学相结合之后，考古年代学才真正建立在可靠的基础? Archeology is the science of time. Archeologists usually rely on stratigraphy and typology to judge the relative age. This method of dating, which has made a significant contribution to archeology, is still useful today. However, its limitations and imperfections are obvious. It can not judge the absolute age. After the introduction of the technology of dating and archeology, or the combination of archeology, the archeology was truly based on a solid foundation?
