beta decay

音標(biāo)發(fā)音

A better idea springs from the weak force【2】, which governs certain nuclear processes, including radioactive beta decay.
比較好的意見是后來突然提出來的稱為“弱力”的理論，這種“弱力”控制了某些核過程，其中也包括了放射性的β衰變。
He is most noted for his work on beta decay, the development of the first nuclear reactor, and for the development of quantum theory.
他的最主要的成就在于貝它衰變理論，建立了第一座原子反應(yīng)堆以及量子論。
I'm not gonna talk too much about the but in the fertile to fissile chain if you look uranium 238 it captures the neutron, 239 by beta decay 239 goes to neptunium, neptunium to plutonium 239.
我不會(huì)談太多,但是在可轉(zhuǎn)換和可裂變的連鎖里，如你們看鈾,238，它捕獲了中子，239，通過β衰減,變成镎，镎變成钚。

What could happen in beta decay is another elusive issue, but a new particle could be implicated there.
FORBES: Higgs Boson Discovery Has Been Confirmed

the radioactive transformation of an atomic nucleus accompanying the emission of an electron. It involves unit change of atomic number but none in mass number (Also called beta transformation, beta process)
