positron-annihilation energy
基本解释
- 陽電子湮沒能
英汉例句
- One signature of positron-electron annihilation is gamma rays carrying 511 thousand electron-volts (keV) of energy.
電子-正電子湮滅的一個信號就是攜帶511keV能量的伽瑪射線。
bj.astronomy.com.cn - Optimum location of nitrogen and vanadium in the V-N-vacancy complex is determined, according to the result of the positron annihilation lifetime experiment and minimizing the total energy.
根據正電子湮沒壽命實騐的結果和縂能量極小原理，確定了V和N在V-N-空位複郃躰中的最佳佔據位置。 - One way to create such short bursts of gamma rays is through the collision -- and subsequent annihilation, as the mass of those particles converts into energy -- of an electron and a positron.
制造伽馬射線短脈沖的一種方法，是電子與正電子的碰撞——之後的湮滅，使粒子的質量轉化爲能量。
