It turns out that particles in crystals and bubbles in liquidhelium follow the same laws as some of the fundamental particles of nature.
事实证明晶体中的粒子、液氦中的气泡和自然界中一些基本粒子一样，遵循着同样的原理。

Liquidhelium cools infrared detectors, nuclear reactors, and the superconducting magnets used in MRI machines, too.
液氦也用来冷却红外线探测器，核反应堆，以及核磁共振成像器械的超导磁体等。

Spitzer's liquidhelium coolant ran out in May 2009, so this false color view is from two channels that still remain sensitive to infrared light at warmer operating temperatures.
