用∼5μ秒的时间常数测量了裸铜表面和涂层铜表面到饱和液氦的瞬时换热。在另一个实验中，研究了超导导线在温度漂移后的恢复。结果表明，裸露表面和涂层表面有很大的差异，后者在较高的表面热流密度下恢复。涂层表面的恢复时间是温度漂移的光滑函数，而裸露表面的恢复时间则表现出不连续性，且扰动越小，恢复时间越长。
Transient heat transfer from bare and coated copper surfaces to saturated liquid helium was measured with a time constant of ∼ 5 μsec. In another experiment recovery of a superconducting wire after a temperature excursion was studied. The results show a large difference between bare and coated surfaces, latter recover at higher surface heat fluxes. While the recovery time of the coated surface is a smooth function of the temperature excursion, that of the bare surface exhibits a discontinuity, being higher for a small disturbance.
