对Mozzi和Warren的实验数据进行了重新评价。改变了分析技术中的一个数值常数，用连续的分析分布函数代替了Mozzi和Warren使用的原子间距离的离散或非分析分布。他们的总体结论没有改变，但一些结构参数得到了新的值。最可能的Si-O-Si键角是152°而不是144°。这个值与Bell和Dean的发现很好地吻合，他们无法构建144°的成功模型，但与153°的模型吻合得很好。
Abstract The experimental data of Mozzi and Warren have boon re-evaluated. One of the numerical constants in the analytical technique has been altered and a continuous analytical distribution function has boen substituted for the discrete or non-analytical distributions of interatomic distances used by Mozzi and Warren. Thoir overall conclusions are not altered, but new values are obtained for some of the structural parameters. The most probable Si-O-Si bond angle is found to be 152° instead of 144°. This value is in good agreement with the findings of Bell and Dean who were unable to construct a successful model with 144°, but found satisfactory agreement with 153°.
