EFFECT OF A NONUNIFORM MAGNETIC FIELD ON THE TIME 
OF LONGITUDINAL RELAXATION T1 OF A FLOWING LIQUID

UDC 589.183

The behavior of the time of longitudinal relaxation 
T1 for a flowing liquid in the strong nonuniform 
magnetic field of the magnet polarizer of a nuclear-magnetic-resonance 
(NMR) flow meter is studied theoretically and experimentally. An increase 
in the nonuniformity of this field reduces T1. The 
magnitude and nonuniformity of the field have an optimum whose criterion 
is the signal/noise ratio in the recording scheme for the NMR signal 
and the weight and dimension characteristics of the instrument.
