These positrons then come into contact with electrons in the body, and the two annihilate, releasing two gamma-ray photons.
正电子与人体组织中的电子发生作用而湮灭，产生两个伽玛射线光子。
Another way to probe the particles' properties is to look for the gamma-ray radiation produced when two WIMPs collide and annihilate each other, producing a cascade of particles and photons.
另一种探明粒子性质的方法是观测两个WIMP的碰撞湮灭，此过程同时产生的一系列粒子和质子，产生伽马射线放射物。
