However, a range of cryogens, especially LOX, Liquid Hydrogen (LH2), Liquid Methane (LCH4), and Liquid Helium (LHe), have been used over the years for two primary applications: cooling of superconducting magnets and space, the latter being the primary focus of the present study. In the ...
液氦最主要的用途是低温超导技术上应用。如:超导技术和磁共振成像(MRI+NMR),超导粒子加速器超导磁体的冷却,用于军事和商业目的的磁流体推进系统,大型强子对撞机设备、核聚变设备的冷却,还有大量科学设备需要液氦超低温环境。 三、液氦--永久液体? 在获得液氦之后,人们随即期望进一步将其固化。然而当时的人们并不知道,...
The solubility of helium in liquid hydrogen has been measured as a function of temperature and pressure. It was found the solubility varied from 0.59 mole % for T=26.8°K and 1.98 atm partial pressure of helium to 11.1 mole % for T=19.8°K and 7.0 atm partial pressure of helium.关键词...
We have calculated the contribution of the triple-dipole three-body interactions to the ground-state energy of liquid Heand solid He. The liquid calculation was done by a Monte Carlo method using a variationally determined product wave function, and the solid calculation by evaluating the triple-...
