THEORY OF AMPLITUDE NUCLEAR MAGNETIC RESONANCE CONVERTER (TEORIYA AMPLITUDNOGO YAMR PREOBRAZOVA TELYA),
Abstract
The theory of an NMR-converter, the basic element of which is an induction coil with the investigated substance placed inside it, is considered. A vector diagram is presented, allowing the interrelationship between the different coil parameters to be traced graphically. It follows from the diagram, in particular, that the effect of the emf developed at resonance is equivalent to the corresponding change in resistance. The method for constructing the circular diagram is used to investigate the dependence of the complex voltage drop at the coupled impedance on detuning from the resonance condition. Analysis of the procedural errors is carried out, and recommendations for increasing the accuracy of measurements are given. The requirements imposed on the measuring circuit are analyzed. The theory of an NMR-converter as applied to NMR-hygrometers is considered. (Author)
