| 摘 要： | 随着同位素测年技术的提高,同位素年龄资料越来越丰富,这就给存储和管理这些资料提出了更高要求。以VisualFoxPro为软件平台,开发了一个以前寒武纪铀铅、钐钕和铷锶同位素年龄及相关资料为主的数据库管理系统,该系统为有关数据的存储、管理、修改和更新及有效使用提供了方便。 |

| Abstract: | As the methodology of dating is unceasingly improving and the isotopic chronologic data are becoming more and more complicated, database management technique should be introduced into geochronology. A geochronologic database system on the basis of Visual FoxPro has been founded in China in which the pre-Cambrian U-Pb , Sm-Nd , Rb-Sr isotopic chronologic dates are used . The test results show that it is an effective means to store, input, modify and renew the isotopic chronologic data. |
| Keywords: | Isotopic chronologic dates Database system Pre-Cambrian |
