摘　　要：本文研究了过冷态超流氦(HeTIp)中的最大临界热负荷q_R和最小临界热负荷q_R。从相界面的传热传质出发推导出了q_p及q_R理论表达式,所导出的q_p理论式及q_R半经验式由于采用了“相对临界热流密度法”撇开几何因子因而具有广泛的应用范围,该理论解与实验结果符合得较好。This paper studys the peak and recovery heat flux densities ( qp,qR ) in the bath of subcooled superfluid helium. On the base of heat and mass transfer through phase interfaces the theoretical relations, without geometrical parameters, of qp and qR are derived, which have very wide application range due to the 'relative critical heat flux density method' for the calculations. The theoretical results fit the experimental results well both for qp and qR .
