Where do protons come from in particle accelerators? Why an electron does not fall into the nucleus of the atom? Why is there no strong force between neutrons? How are protons and neutrons similar? Where do the protons come from in photosynthesis?
解析 就是单数复数啦... 比如说proton就是一个质子,protons就是多个质子……氢就是one proton…… 在这几个词中,nucleus比较特殊.nucleus是单数,nuclei是复数【参见半径单数=radius复数=radii】 分析总结。 比如说proton就是一个质子protons就是多个质子
