摘要：

For pyroelectric glasses, the nonapplicability of the Third Law of Thermodynamics is shown to imply that the pyroelectric coefficient p (T) remains nonzero as the temperature T tends to zero. The ratio, p/C, C being the specific heat, is also shown to be proportional to T-1 in the low-temperature limit.
