These signals are produced by colliding stars or nuclear reactions in outer space 这些讯号是由外层空间的星球碰撞或者核反应所造成的
Nuclear reactors might be used to melt frozen gases and eventually build up the atmosphere 核反应可以用来融化冰冻的气体最终形成火星大气层。
The recoil atoms with high energy and the residual nuclear are dealt with in a strict way 计算中对核散射产生的次级粒子及核反应剩余核都进行了跟踪。
Xenon possesses nine stable isotopes , produced in various proportions by different nuclear processes 氙具有九种稳定的同位素，在不同的核反应中所产生的比例不同。
The lack of { + 7 } li , meanwhile , has been blamed on over - hungry nuclear reactions in stellar cores 同时，在星体核中进行的过于强烈的核反应也致使了{ + 7 }锂元素的消失。
Finally , after millions of years , and well after the nuclear chain reactions terminated , xenon 129 formed 最后，经过了几百万年，连锁核反应结束许久之后，氙129才产生。
For example , production of xenon 136 began at oklo only about a minute after the onset of self - sustained fission 例如在欧克陆，自我持续的核反应开始约一秒后就产生氙136 。
Once they had had their catalytic effect , they would have split back off again and gone their own ways 一旦核反应发挥了其催化性效果，它们将再一次地倍分裂并重复其原始运动方式。
" for his contributions to the theory of nuclear reactions , especially his discoveries concerning the energy production in stars 核反应理论方面的贡献，特别是关于恒星能源的发现
