用x射线衍射法研究了由冲击恢复实验获得的冲击诱导钙长石玻璃的结构，并与熔融钙长石玻璃进行了比较。该玻璃的衍射曲线峰谱比熔融玻璃的衍射曲线峰谱宽。径向分布函数表明，在熔合玻璃中基本结构单元也为TO4 （T = Si, Al）四面体，具有与熔融玻璃相似的连接。折光玻璃的径向分布曲线的波峰比熔融玻璃宽。因此，透光玻璃的原子有序排列范围似乎比熔融钙长石玻璃小。与Ca相关的峰的宽度更明显。
The structure of shock-induced anorthite-glass obtained by shock-recovery experiment, which is called “diaplectic glass”, has been investigated with X-ray diffraction method and compared with that of fused anorthite-glass. The peak profiles on the diffraction curve of the glass are broader than those of the fused glass. The radial distribution function indicates that the basic structural units are TO4 (T = Si, Al) tetrahedra also in the diaplectic glass, having similar linkages to those in the fused glass. The peaks of the radial distribution curves are broader in the diaplectic glass than in the fused glass. Therefore, the range of ordered arrangement of atoms of diaplectic glass seems to be smaller than fused anorthite-glass. The broadness is more distinct in the peaks related to Ca.
