摘要：

A measurement of the proton gyromagnetic ratio in water by the low-field method is in progress. The earth's magnetic field is compensated down to 1 nT at the center of Helmholtz coils in the constructed nonmagnetic facilities. The solenoid former of fused silica has been fabricated by the screw grinding and lapping within the dimensional variations of a few micrometers.
