【Abstract】 Internal strains in eight different directions in ruby single crystals are measured from the reflection pseudo-Kossel pattern. By solving the corresponding average strain and stress tensors, the internal stresses of three dimensions in the crystals can be calculated. Since internal stress is an important parameter for appraising the quality of rudy, the method mentioned above is recommendable.更多还原
