摘要：

The surface conductance coefficient H of a cylindrical iron bar is calculated from experimental measurements of the temperature distribution in the steady state and during cooling. In the steady state, H can be considered constant, with fluctuations within statistical error. In cooling, there are two H coefficients: one governing the sharper temperature fall over short times, and the other governing the smoother fall over longer times.
