The antielectron, or positron, was discovered in 1932.
反電子或正電子,是在1932年被發現。
The nuclide chart involves electron, positron, antiproton, antineutron, photon to exhibit the symmetry of mass and charge ideally.
該核素圖將電子、正電子、反質子、反中子和光子收錄在內，完美地表現了質量和電荷的對稱性。
The key of this technology depended on increasing batteries positron electrode -- zincous -- the electron that can carry.
這項技術的重點在於增加了電池正電子電極——陽極——所能攜帶的電子。
When two such gamma-ray beams collide, the interactions are even cleaner than electron-positron or muon-antimuon collisions.
當這樣的兩束伽瑪射線碰撞時，其交互作用比「電子╱正子」或「緲子╱反緲子」的碰撞更乾淨。
