Data from the Wilkinson microwave Anisotropy Probe (WMAP) can show the minute temperature changes created as the cosmic microwave background radiation moves through gases in galaxy clusters.

从威尔金森微波各向异性探测器(WMAP)得来的数据显示出，细微温度变化是在宇宙微波背景辐射移动通过银河星系团气体时产生的。

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。

Passive infrared penetration is poor, the human body easily block the infrared radiation not be receiving probe.

被动红外穿透力差，人体的红外辐射容易被遮挡，不易被探头接收。
