摘要：

Specific heat measurements were performed between 0. 1 and 1 or 2 K on B//2O//3 and Si0//2 glasses, which were stabilized near Tg by thermal treatments. Although permanent variations of the density up to two percent were obtained for B//20//3, this induced only a slight modification of the specific heat related to the two-level systems.
