annihilation radiation

基本解释

Optical absorption spectra and positron annihilation radiation Doppler broadening were measured at room temperature.
在室温条件下测量了吸收光谱与正电子湮没辐射多普勒展宽谱。
Upon collision, the conversion of a PARTICLE and its corresponding antiparticle into pure electromagnetic ENERGY (called annihilation radiation).
粒子和对应的反粒子碰撞后，被完全转化为电磁辐射能量。
