“…Variability, like the central value, is a precise and reproducible identifying characteristic. Similar to the example provided in Central Tendency, when two blood specimens have markedly different variability in RBC volume, it suggests that the specimens come from different patients, different times, or different circumstances ( 8 , 9 ).…”

“…The interpretation of the NMR line-shape of silica glass is based on the knowledge of a relation between the chemical shift and the Si-O-Si angle. Four such relations are discussed in reference [17]: The secant [38], the linear [39] ,the point charge [40] and the s-hybridization [41] model. The secant and the s-hybridization model produce almost identical Si-O-Si angle distributions and are not considered separately.…”

The distribution of Ge-0-Ge and Si-0-Si bond angles a in amorphous germania and silica is re-determined on the basis of diffraction experiments. The bond angle a joining adjacent tetrahedra is the central parameter of any continuous random network description (CRN) of these glasses. New high energy photon diffraction experiments on amorphous germania (at photon energies of 97 and 149 keV) are presented, covering the momentum transfer 0.6-33.5 A -'. In photon diffraction experiments on GeO, the contribution of the 00 pairs is very small. To obtain a similar information for amorphous SiO,, high energy photon diffraction experiments [l] have been combined with neutron diffraction data 12, 31 on amorphous silica in order to eliminate the 00-partial structure factor. With this technique it is shown that the Si-0-Si angle distribution is fairly narrow (a = 7.5") and in fact comparable in width to the Ge-0-Ge angle distribution (a = 8.3'), a result which differs from current opinion. The narrower distribution found in this study are in much better agreement to the determinations based on 29Si-MAS-NMR. Among the various models relating the chemical shift to the bond angle, best agreement is found with those models based on the secant model. Sharp components in the bong angle distribution can be excluded within the reached real space resolution of 0.09 A.
