摘要
Peak and recovery heat flux densities(q_(p),q_(R))in the bath of subcooled superfluid helium(HeIIp,from 1.81 to 2.1 K at 0.1 MPa).Have been measured,in which a programmed voltage method with a triangle waveform of 20s is applied,and a RhFe wire(d=51μm,L=34.8mm)is horizontally immersed in a HeIIp cryostat,which served as sample,heater and temperature sensor.
