Results There were no significant differences in operating room temperature, operative time, anesthetic time, the volume of blood transfusion and fluid transfusion between 2 groups(P>0.05).
结果 试验组与对照组手术室温度、麻醉时间、手术时间、术中输血量及补液量，各指标组间差异均无统计学意义（P＞0.05）。
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.
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。
