摘要：
This paper experimentally and theoretically investigated heat transfer process of complex-vacuum-multilayer-insulation cryogenic tank after a sudden loss of insulation vacuum (SLIV). The experiments were conducted with the breakdown of the insulating vacuum with nitrogen, atmospheric air, helium and a model describing heat transfer process after SLIV was proposed. The calculated results agreed well with the experimental data. The maximum heat flux appeared when helium served as leaking gas.
