摘要：

General equations are derived describing crystal lattice distortions determined by X‐ray measurements of the local spacing and orientation variations of reflecting crystal planes. It is shown that the tensor of crystal lattice distortions corresponds to the sum of elastic distortions due to dislocations and total distortions due to nondislocation sources (impurities, nonuniform temperature distribution, etc.). The measured distribution of crystal lattice distortions provides the simultaneous determinations of the dislocation density tensor and the nonuniform distribution of nondislocation sources (e.g., impurity concentration gradient).
