由于是冷凝低温式机器(冷凝泵在密闭腔内能产生高真空环境，带电粒子在高真空中才能生存：译者注)，运行时候温度极低，LHC要回到常温大概要一个月，并且致冷过程也要花费一个月。
Being a cryogenic machine operating at very low temperature, the LHC takes about a month to bring up to room temperature and another month to cool down.
每个传感器芯片都在极为精确的湿度腔室中进行标定，以镜面冷凝式湿度计为参照。
Each SHTxx is individually calibrated in a precision humidity chamber with a chilled mirror hygrometer as reference. The calibration coefficients are programmed into the OTP memory.
冷却时未冷凝的燃料蒸汽通过位于腔室顶部的浮动针阀可以从腔室中逸出。
Fuel vapor that is not condensed as a result of cooling can escape from the chamber through a float needle valve at the top of the chamber.
