摘要：
A mathematical model is developed for the deformation of glass components with curvilinear axisymmetric surfaces, produced by gravity during annealing. Comparison between model calculations made for components with spherical and elliptical surfaces and direct measurements have shown that the model accounts satisfactorily for the change in the height and volume of the components, but not for the change in the shape of their surfaces.
