TWO MOLECULAR MODELS FOR STUDYING THE STABILITY OF SILICATES

<正> Studying silicates by quantum chemistry, the calculation models of both the silioxenes and the silicic acids were used internationally. The calculated results from these models have been applied to the discussion of the geometric configuration, electronic states density and spectra of silicates, and they are in agreement with expeximental facts. However, these molecular models have not been used in studying the relative stability of silicates so far.
