常見(jiàn)例句

This chart gives you a summary of some of the critical thermal-neutron cross sections of important fissile and fertile nuclides.
這個(gè)圖表給你們一個(gè)重要的,可裂變和可轉(zhuǎn)換核素的,一些臨界熱能中子橫截麪的縂結(jié)。
We can then look at uranium 238 which has a relatively low absorption thermal energy range and essentially has no fission cross section which is why we call uranium 238 a fertile atom.
我們能看看鈾238，它有一個(gè),相對(duì)低的吸收熱能範(fàn)圍,基本上沒(méi)有裂變橫截麪,那就是爲(wèi)什麼我們稱鈾238爲(wèi)可轉(zhuǎn)換核素。
