摘要：

Low-resolution proton nuclear magnetic resonance spectroscopy is a rapid and accurate technique for measuring moisture in coal and total solids in aqueous coal slurries. The adverse effects of ferromagnetic materials, such as magnetite, have been catered for by the use of a variable-gate technique. Routine measurement of these parameters by this n.m.r. method now appears possible. © 1979.
