Electric effects for elastic actions on crystals of NaCl
Tóm tắt
This work reports measurements of the differences of potential ΔV that are generated in crystals of NaCl subjected to unidirectional compression for loads such as to remain within the limits of validity of Hooke’s law and beyond them, and furthermore, the law of variation of ΔV with time, depending on the stresses applied to the crystal and the temperature.
