摘要：

A redesigned oscillating-cylinder viscometer for low-viscosity fluids up to 1200 degrees C is described. Absolute viscosities are calculated from logarithmic decrements obtained by time measurements using fixed photodetectors. The digital data acquisition system is computer-facilitated and highly automated. The cylinder may be a solid disc submerged in the liquid, or a cup containing highly volatile melts. The viscosity of molten NaCl is determined over the temperature range 810-930 degrees C.
