Abstract. A method is proposed to improve the accuracy of measurement of longitudinal and transversal relaxation time (relaxation constants) of flowing fluid with nuclear-magnetic spectrometer. Experiments are carried out to study the effect of analyzer and registration coil size on signal-to-noise ratio at the output of registration system of nuclear-magnetic resonator, as well as on inhomogeneity of the analyzer magnetic field in the vicinity of the registration coil.
Keywords: analyzer, magnetization, longitudinal relaxation time, transversal relaxation time, registration coil
