摘　　要：熔体粘度的测量,在粘度低于0.01Pa·s,温度超过500℃时,(?)是一个比较困难的课题。各种测量方法中,以扭摆法应用较广泛。该法一直采用灯一尺结构读取数据。本文首次研制出了具有光电转换的自动记录衰减曲线的熔体粘度计。Measurement of viscosity of melt is a difficult work when the viscosity is less than 0.1p and measuring temperature is higher than 500℃.Among the measuring methods,oscillating crucible method is in common usein which the light-rulor is used to record the datum,it is not very convenientand accurate.This paper will report a new viscosimeter in which photoelect-ric conversion of the signals is realized through the polarizing disc and att-enuation curve is recorded automatically.
