摘要：

The thermal conductivity of very slowly deposited amorphous ice derived from experimental results is shown to be a factor of 10(-4) to 10(-5) less than hitherto estimated. Using the exceedingly low value of the thermal conductivity of comets deduced from the amorphous ice properties leads to the expectation that internal heating of comets is negligible below the outer several tens of centimeters.
