低温暗物质研究II号在极度低温中进行，并侦测（暗物质）粒子在探测器重撞击锗元素以及硅晶体时释放的能量。

CDMSII operates at extremely low temperatures and detects the energy released when particles hit atoms in germanium and silicon crystals within the detectors.

然后他一跃自由而下，自由落体时的降落速度高达982公里/小时，几乎接近了1200公里/小时的声速，而且他还经历了零下52摄氏度的低温。

He then leaped and freefell at speeds of up to 614 mph, not far from the speed of sound's 761 mph, and endured temperatures as low as minus 94 degrees Fahrenheit.

In principle, this value, this efficiency, can approach 1 as the low temperature approaches absolute zero.

这个值，效率，当低温热源的温度1,是据对零度时可以达到一。
