同样的，星球也有无数的方法能够丧失自己的大气层，有可能被太阳风夺走，还有可能被太阳的放射性物质或者来自彗星和小行星灾难性的撞击耗尽。
Similarly, there are myriad ways that planets can lose their atmospheres, through stripping by the solar wind, baking by the sun's radiation or catastrophic impacts by comets or asteroids.
这四种新元素都是人造的，是由火花与原子核相互撞击并且循着放射性超重元素衰变的轨迹而发现的。
The four new elements, all of which are synthetic, were discovered by slamming lighter -nuclei into each other and tracking the following decay of the radioactive superheavy elements.
中微子是创建作为放射性衰变或核反应，如某些类型的结果，在阳光下放置在核反应堆，或当宇宙射线撞击原子。
Neutrinos are created as a result of certain types of radioactive decay or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms.
