摘要：

A theoretical model is suggested which describes misfit defect structures at crystal-glass interfaces. In the framework of the model the two basic types of misfit defect are distinguished misfit disclinations (generated as extensions of parent disclinations present in the adjacent glassy phase) and 'dilatation' misfit dislocations (contributing to accommodation of the dilatation misfit associated with difference between the characteristic interatomic distances in the adjacent crystalline and glassy phases). The elastic energy density of crystal-glass interfaces is estimated.
