(1) Low temperature engineering application of helium gasIt is well known that the liquid temperature range of xenon is 2 x 10-3 - 5.20 K, the liquid temperature range of hydrogen is 14.2 - 33.0 K, and the liquid temperature range of helium is 24.5 - 44.40 K.Because helium is chemically inert and ha

Oxygen is our basic survival conditions, no oxygen, we cannot survive, we can see some patients in the hospital is needed medical oxygen tanks, because these patients only by providing oxygen, oxygen tank to breathe normally, so for the oxygen tank storage have strict requirements. So what are the a

Generally, a substance that is in a gaseous state at normal temperature and pressure is called a gas. A wide variety of gases, classified by nature, can be divided into inorganic gases and organic gases; according to ancient classification, can be divided into constant gas and trace gases, classifie

The gaseous fuel can be directly used as a fuel for an internal combustion engine or the like, and can also be used as a raw material for industries such as synthetic ammonia, artificial petroleum, and organic synthesis.Gas fuel is a kind of high-quality, high-efficiency and clean fuel. Its ignition
