N2 - The paper presents the results of temperature dependence measurements for the rate of proton relaxation (1/T1) in sea water with salinity 35‰ over the temperature range -22-+120°C at atmospheric pressure and in some salt solutions at two concentrations (0.5 and 1 mol/l). The possibility of approximating the temperature dependences of magnetic relaxation rates by various functions in pure water, sea water, and solutions of salts with various concentrations was studied. The parameters of these dependences and trends of their variations under the influence of salt components are reported. The most well grounded method for the functional representation of the temperature dependences of 1/T1 is the use of the sum of exponents with the number of terms depending on solution concentration.
