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

该核素图将电子、正电子、反质子、反中子和光子收录，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.

这项技术的重点于增加了电池正电子电极——阳极——所能携带的电子。
