摘要
本文指出书刊上介绍的在铸造生产中以流杯粘度计的流动时间为粘度是不妥的,因为在测粘过程中不存在确定的仪器常数。选择该粘度计的出口形状,流动时间就反映粘度。
In this paper we elucidate unsuitable method that the flowing time infoundry produce by cup--shaped viscosimeter is taken as the measure forviscosity, Which is recommended in some books and magazines, Becausethere is no fixed constant of instrument in viscosimetry choise of a prop-er shape for viscosime?er's exit, that can make flawing time to expressviscosity.
