The antielectron, or positron, was discovered in 1932.

反电或正电,是在1932现。

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

该核素图将电、正电、反质、反中和收录在内，完美地表现了质量和电荷的对称性。

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了电池正电电极——阳极——所能携带的电。

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)正电射型体层摄影术(PET)全身显像在原灶不明转移癌中的作用。
