Because the Moon was closer [translate] awere shorter, tides greater, storms more severe. The skies were a hazy [translate] awas rich in nitrogen, carbon dioxide, and water vapor but contained only trace amounts of oxygen gas (02 ) . [translate] ...
INFRARED LASER WITH DISCHARGE GAS INCLUDING CARBON DIOXIDE,NITROGEN AND WATER VAPORinfrared laser with discharge gas including carbon dioxide,nitrogen and water vaporWitteman, Wilhelmus Jacobus
A commercial Fourier transform infrared spectrometer (modified to improve the purge) and a long-path gas cell were used to demonstrate a detection limit of about 10 ppb for water in N-2, HCl, and HBr. This technology is being developed as an in-line monitor to extend the life of gas de...
摘要: Molecular masers have been used to measure the refractive index of nitrogen, water vapor, and their mixtures at wavelengths of 337micro, 311 micro, and 28 micro. A discrepancy between the new measurement and microwave values for pure nitrogen is at present unexplained....
I think this way can resolve conflicts between doctors and students effectively. 正在翻译,请等待... [translate] aThe nitrogen gas carried the VOC vapor into the U-shaped glass tube containing weighted activated carbon sample. 氮气气体运载了VOC蒸气入包含被衡量的被激活的碳样品的U形玻璃管。 [...
Nitrogen-filled tires have a longer lifebecause they don't have the corrosive properties that come with air-filled tires, mainly the oxygen and the water vapor. Not only does oxidation ruin the rubber in the tire, but both the oxidation and the water vapor can affect the aluminum and steel...
An open-cycle thermodynamic engine using a working fluid which is a gas at ambient conditions and which is liquefiable at temperatures below ambient. The engine operates by compressing the working fluid, such as liquid nitrogen, with a pump, convectively heating the nitrogen in a heat exchanger,...
