这样，正常电子的反粒子叫做正电子，如同它有一个阳电荷一样，但是与电子的质量一样。

The process of beta decay increases or decreases the positive charge of the original nucleus by one unit without changing the mass number.

衰变过程使母核增加或减少一个单位的正电荷而不改变它的质量数。

In some kinds of beta decay, a nuclide loses surplus positive charge by emitting a positron (in the same event, a proton becomes a neutron, and neutrinos are also given off).

以某种贝它衰减，一个核素靠发出一个正电子失去剩余正电荷(在相同的事件中，一个质子变成一个中子，而且也发射微中子)。

Two kinds of water-soluble biomimetic chitosan derivatives with a phosphoramide linkage between glucosamine and choline were prepared through Atherton-Todd reaction under the mild conditions, including zwitterionic phosphorylcholine bound chitosan and acetyl-phosphorylcholine bound chitosan with positive charge. The interaction between chitosan derivatives and calf thymus DNA were inversigated by UV alsorption spectra and circular dichroism spectra.

According to Canterbury, when we expend energy, the molecules in our body are left holding a positive charge.

据坎特伯雷，当我们付出的能源，在我们的身体留下的分子持正电荷。

"Deuteron:The nucleus of a deuterium atom, consisting of a proton and a neutron, regarded as a subatomic particle with unit positive charge."

"氘核：氘原子的原子核，由一个质子和一个中子组成，被视为带单位正电荷的亚原子。"

Cyclodextrin linked to the guanidine causes more positive charge localizing at the central Cu cation of {[Cu (H2O)]2}(superscript 3+), which is favorable to catalyze the dismutation reaction.
