Oxygen bottles and acetylene bottles should be kept at a distance of 10 meters from the hot spot during construction work. The distance between the oxygen bottle and the acetylene bottle should be kept at 5 meters or more. The length of the primary wire (ground wire) of the welding machine should be

(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
