So light can be slowed down, but not sped up: the vacuum is nature's open road where light travels at the speed limit.
所以说,光速可以减慢却不能加快:真空好比是自然界的康庄大道,光便以其极限速度疾驰在这条大道上。 欧洲粒子物理研究所的实验室里到底发生了什么?
With some hazardous materials, you can provide further protection by using inert gas to limit the oxygen level in the vacuum dryer.
随着一些有害材料,可以提供进一步的保障真空干燥机使用惰性气体中氧气含量的限制。
The effect was obvious to select four-star connection MOA was a main protector to limit overvoltage in operation of a vacuum disconnector.
选用四星型MOA作为限制真空断路器操作过电压的主保护器,效果十分明显。
The dezincing limit from molten lead by vacuum refining process is studied by theoretic analysis and experiments.

Higher temperature, oil temperature increase, decrease viscosity, steam increased, the limit will cause a vacuum up, we should strengthen the ventilation cooling.
环境温度较高时,油温升高,粘度下降,饱和蒸汽增大,会引起极限真空上升,应加强通风散热。
