摘要：

A detailed study of 29Si NMR of different silicas and the quantitative relationships that can be derived from the 29Si spectra are discussed. Special emphasis is placed on the difference of chemical shift observed between CP/MAS and simple MAS spectra. Effects of a thermal treatment on 29Si NMR features are also discussed. © 1990.
