the result shows that the rapid neutron capture process ( r-process) is the main source of neutron capture elements in poor-metal stars. besides, the yields of heavy neutron capture elements in stars whose metallicity is less than-2.5 may come from pure r-process.

结果显示，快中子俘获过程（r过程）是贫金属星中子俘获元素的主要来源，且金属丰度小于-2.5的贫金属星的重中子俘获元素产量可能来自于纯r过程；
