RÉSUMÉ

Refraction indexes of water samples from different springs and their dependencies upon temperature are studied in the millimeter wavelength range using the vibrating string method. It is established that the temperature dependence of the refraction index in the temperatures range under investigation can be approximated by the linear dependence. It is shown that the coefficient of linear regression of temperature dependence allows one very fay belonging of waters to different springs.
