已知的用于确定粘度计常数的装置是一个容积为200cm~3充满蒸馏水的烧瓶,而流出时间用机械秒表记录。这种装置的缺点是:确定粘度计常数的精度低,以及存在操作者的主观误差。为了提高常数的测量精度研制出一种装置,在这种装置中用在烧瓶上装电接点(安装
The known device for determining the viscosity of a viscometer is a flask filled with distilled water having a volume of 200 cm to 3 and the flow-out time recorded with a mechanical stopwatch. The disadvantage of this device is that the accuracy of the viscometer constant is low and there is subjective operator error. In order to improve the measurement accuracy of the constant, a device was developed in which the load contacts on the flask
