摘要

Steady state heat transport through He II was investigated. The exponent m in the Gorter-Mellink equation which gives heat flux dependence of the temperature gradient was measured in a wide range of heat flux. Our results indicate that there is no heat flux dependency of the exponent m in the heat flux region of our measurement. The exponent m is 3.4 at temperatures much lower than the lambda point and decreases down to 3.3 as the temperature approaches the lambda point.
