1·The coefficient of performance at cryogenic temperatures is typically 4-5%.
在性能系数在低温的温度通常是4 - 5 %。
2·The interior of the chamber then provides a gaseous environment at cryogenic temperatures.
这样，腔室内部提供了处于低温温度下的气态环境。
3·The large size of the chlorine ligand means that XeCl2 can only be made and used at cryogenic temperatures.
氯配体体积比较大，这意味着：XeCl2 只能在低温下制备和使用。
4·Some experts thought the bat may have been frozen in place because of the cryogenic temperatures, but it changed position every now and then.
一些专家认为蝙蝠可能是因为超低温而被冻结在了外壁上，但那只蝙蝠每隔一会儿就变换一下姿势。
5·Frozen brain slabs are kept at cryogenic temperatures until they are further sliced and eventually probed with RNA to look for specific gene expression.
冷冻的大脑切片被保存在低温条件下，直到进行进一步切片处理并最终用RNA加以探测，以寻找特定的基因表达。
6·The most commonly used industrial gases that are transported, handled, and stored in the liquid state at cryogenic temperatures are argon, helium, hydrogen, nitrogen, and oxygen.
氩、氦、氢、氮和氧是在低温以液体状态运输、操作和储存的最常用的工业气体。
7·Some of the potential reagents are very fragile and will need to be used at cryogenic temperatures, but the elimination of an atom of an almost inert gas can simplify the chemistry.
有些可能的试剂非常不稳定，需在低温下使用，但是，如果一个原子的几乎是惰性的气体消除了，就能够让化学过程简化多了。
8·A conventional thermos isn't good enough, but a Dewar flask, invented in the 19th century, holds cryogenic fluids like liquid nitrogen at temperatures of -196oc (-321of) for months at a time.
传统的恒温器不够好，但是19世纪发明的Dewar flask一次能保持像液态氮这样的温度在- 1960华氏摄氏度的低温液体好几个月之久。
9·Their extremely low temperatures can produce cryogenic burns of the skin and freeze underlying tissue.
它们的超低温会造成皮肤冻伤和皮下组织冻结。
10·There are a number of general precautions and safe practices that must be observed because of the extremely low temperatures and high rates of conversion into gas of all the cryogenic liquids.
由于所有低温液体的极低的温度和极高的气化率，必须遵守许多的通用防范措施和安全惯例。
