对这些正电子有一个可能解释，就是它们来自同一种暗物质以正、反物质形式出现的一对粒子的碰撞（物质湮灭），这样的暗物质又被称为“大质量弱相互作用粒子”（WIMP）。
One possible explanation for these positrons is the mutual annihilation of the matter and antimatter forms of a type of dark matter called weakly interacting massive particles, also known as WIMPs.
用正电子湮没寿命谱研究了手性丙烯酸酯侧链液晶共聚物分子主链与介晶基元侧链的运动行为及相互作用。
Motional behaviour and interaction between main chain and side chain of mesogenic moiety of liquid crystalline copolymer were studied by positron annihilation lifetime spectroscopy.
当两个大质量弱相互作用粒子碰撞时，它们会彼此消灭，从而产生另一些粒子——比如正电子。
When two WIMPs collide, they can annihilate each other, giving rise to other particles—such as positrons. The data from AMS so far match these predictions.
