摘要：
The second harmonic generation technique has been used to evaluate combinations of third-order elastic constants (TOEC) of NaCl between room temperature and liquid-nitrogen temperature. TOEC data at room temperature are compared both with theory and other experimental results. The temperature variation of C111 is somewhat larger than predicted by theory. The temperature behavior suggests that a noncentral force and other exchange interactions predominate at 0 K.
