数码辅助方法在毛细管流变仪测量粘度的应用

Digital Method Aided Measurement on Viscosity by Capillary Rheometer

讨论了传统流变仪测量粘度上存在的问题，提出了改进的方案测量粘度，以减少误差。试 验方案主要体现在用数码方法采集数据。

This article discusses the problems exist in the measurement of the viscosity by the traditional rheometer and the continuous extrusion rheometer,at the same time we propose the improved method to measure the viscosity of polymer,and reduce the error.The difference is pre- sented on the digital methods on the data collection.
