The low Th and U content of the copper ores suggests that the Pb isotopic compositions of this type of ores are normal lead instead of radiogenic lead.

而且，铜矿石的低U、Th含量为该类铜矿石的铅是正常铅提供了合理的解释。

Important advance are made in the date of slices and superslices:(1) Abundant acritarch and a few radiolarian fossils are collected in the "barren strata" formed by epi-middle metamorphic slices at Gouli, Longshigenggongwu, thus provide data evidence for this set of strata. A series of isotopic dating data (14) showed that the date are between 1 000 Ma and 500 Ma, close to that of the fossils.

在岩片和超岩片时态调查方面取得如下重要进展：(1)在沟里、龙什更公坞等地区的由中浅变质岩岩片构成的"哑地层"中获取较丰富的疑源类和少量放射虫化石，使该套地层从化石方面首次获得了确切的时代证据，并新获一大批同位素年龄数据（14个），年龄值主要分布在1000—500Ma之间，化石时代与同位素测年吻合较好。

By comparing the composition of rare gas elements in the lunar regolith and in the solar wind, the authors analyze the physical, chemical and isotopic effect...

研究了月壤中氦- 3的含量与月壤颗粒大小、矿物组成、元素成分和结构特征的关系，并估算了氦- 3的资源量；探讨了月球表面的反射率；综合分析了月球区域性磁场的形成机制。

And looking back on his own academic work he showed a certain solidarity with his subject's sloppiness:"I'm very grateful that the isotopic composition of helium has not become a key matter of public interest."

回顾他自己的学术研究时，他表达了一些对其调查对象马虎的同袍情，"我很庆幸氦的同位素组成这研究没受到大众关注"。

Based on the data from S0177 leg core, which were collected in SouthChina Sea by German scientific investigation ship – SONNE, our study canbe divided into three parts. The first part is the grain size analysisand data-processing. Then we decided the 14C isotopic age. We summarizedcore characteristic through observing the sample with scan electronicmicroscope.

利用德国"太阳号"在南海的 SO177 航次部分岩芯资料，主要进行了三方面的工作：粒度测试及数据处理、挑选有孔虫化石和加速质谱仪 14C 测年以及利用扫描电子显微镜观察和总结岩芯的微结构特征。
