2010年,刘敦一开始忙古气候变化的量化研究。古气候变化的定量研究一直受到传统氧同位素理论和方法的限制,加上实验仪器的限制,世界上对于该项目的研究一直鲜有进展。工欲善其事,必先利其器。2001年刘敦一接下了一个让他振奋不已的任务:建立离子探针中心。自此,中国开始在二次离子探针质谱领域走向大型仪器共建共享的道路。一把利器刘敦一时常回忆起十年前的情境。那时,价值千万的大型仪器的进口
In 2010, Liu Dun began a quantitative study of paleo-climatic changes. The quantitative study of paleoclimate changes has been limited by the traditional theories and methods of oxygen isotope. With the limitations of experimental instruments, the research on this project in the world has been little progress. Workers want good things, must first sharpen. In 2001, Liu Tunyi took over an exciting task: to establish an ion probe center. Since then, China has begun to move toward the construction and sharing of large-scale instruments in the field of secondary ion probe mass spectrometry. Liu Xiang, a sharp weapon, often recalls the situation ten years ago. At that time, the import of large instruments worth tens of millions
