摘　　要：^C-14是碳同位素家族的特殊成员,不仅具有放射性,而且半衰期长,经过漫长的研究和理论技术积累,其碳定年法技术为考古、第四纪地质、近代海洋等领域研究提供年龄信息。它在自然界中的“特异性”和“普遍性”又使得它具备示踪技术,在宏观大气,海洋及生态领域示踪物料来源,同时在微观的生命科学领域也可揭示生化过程的反应机理,是人类探索自然的好帮手。^14 C is a special member of the carbon isotope family.It not only has radioactivity,but also has a long half-life time.After a long period of research and theoretical accumulation,its carbon dating technology provides age information for archaeology,Quaternary geology,modern ocean and other fields.Its “specificity” and “universality” make it has tracing technology in nature,tracing material sources in macroscopic field such as atmospheric,marine and ecological,and revealing the reaction mechanism of biochemical processes in micro-life science.It is a good helper for human to explore the nature.
