摘要：
The physical phenomena occuring in a diamond-type crystal are usually described in terms of the invariants of some representations of the space group O-h(7). By choosing a new description, we obtain equivalent representations in which the expressions of the usual invariants are simpler. The mathematical facilities obtained by using these representations offer new possibilities for elaborating improved variants of the usual theories or extensions from perfect crystals to crystals with impurities or defects.
