A photomagnetic positronium annihilation model was proposed to explain the experimental facts.

提出正子素光磁湮没模型以解释实验事实。

The antielectron, or positron, was discovered in 1932.

反子或正子,是在1932年被发。

The nuclide chart involves electron, positron, antiproton, antineutron, photon to exhibit the symmetry of mass and charge ideally.

该核素子、正子、反质子、反中子和光子收录在内，完美地表质量和荷的对称性。

The key of this technology depended on increasing batteries positron electrode -- zincous -- the electron that can carry.

这项技术的重点在于增加正子极——阳极——所能携带的子。

Objective To evaluate the value of 18 F-deoxyglucose (FDG) positron emission tomography (PET) in detecting the primary focus of metastatic cancer with an unknown primary.

目的探讨18F-脱氧葡萄糖(FDG)正子发射型体层摄影术(PET)全身显像在原发灶不明转移癌中的作用。
