英文摘要	The quantitative distribution of different Q(i) species in binary calcium silicate glasses and their melts has been investigated by in-situ high temperature Raman spectroscopy, Si-29 MAS NMR and quantum chemistry (QC) ab initio calculations. The structural units and several cluster structure models have been designed, optimized and calculated by ab initio calculations. The attribution of their vibrational modes, vibrational wavenumbers of non-bridging silicon-oxygen (Si-O-nb) and Raman scattering cross sections (SCS) have then been worked out and analyzed. The functional relationship between the SCS and stress index of silicon-oxygen tetrahedron (SIT) was established for the model clusters of delicate Q(i). Quantitative distributions of Q(i) in calcium silicate glasses and melts are finally obtained which are in good agreement with the experimental results of Si-29 MAS NMR. Although the primary structure present in calcium silicate glasses and melts is the same, the relative distribution of Q(i) is different. On the basis of the present work, it will be helpful to predict the physicochemical properties of silicate slag.
