贫金属星 meaning in English
metal-dificient star
metal-poorstar
Examples
- The new rate of 11c ( p , ) 12n is larger by about a factor of 2 than that of ref . [ tan02 ] , and could transfer 3he to cno materials earlier , so that it may act as a seed of the cno cycle and cause the explosive of the massive star
计算结果表明，在某些巨质量贫金属星中， “ he通过“ c ( p ，的‘ zn从p一p链过度到cno循环，有可能起到种子核的作用，引发星体的爆炸，从而改变巨质量星塌缩为黑洞的命运。 - A reaction network program is created and used to analyze the astrophysical effects of the new reaction rates 18f ( p , ) 15o , 18f ( p , ) 19ne and 11c ( p , ) 12n . the new rate of 18f + p could produce form more production of 18f that expected by the rates of ref . [ coc00 ]
最近，我国原子能院就“ c ( p ，的‘ “ n的直接俘获的截面作了间接的测量[ liu03 ] ，我们根据其提供的直接部分的s因子更新了“ c ( p ，的‘ zn的反应率[ liu03 ， shu03a ] ;并利用网络方程计算系统，讨论了该反应率在巨质量贫金属星中的影响。 - The average abundance distributions of heavy elements in metal - poor stars can provide fairly direct and detailed information on the nucleosynthesis in every stage after the formation of galaxies . furthermore , it can put more accurate constraints on the chemical evolution of neutron - capture elements . the solution to this problem will have important effect on the solution to a series of problems about nuclear astrophysics and the galactic evolution
贫金属星的中子俘获元素丰度分布能提供星系形成后各个阶段核合成的较为直接和详细的信息，并为星系化学演化的研究提供更为准确的约束，这一问题的解决将对核天体物理及星系化学演化的一系列问题的解决产生重要影响。
