摘　　要：本文介绍在西德HAAKE公司RV2型旋转式粘度计上配置微计算机,并设计A/D转换接口和软件,完成粘度测试的数据采集与数据处理的方法,利用IBMPC微机进行数据采集,粘度计算、结果打印,曲线绘制。由于采用一种具有保凸性质的样条函数—Bézier曲线拟合方法,使得粘度曲线得到最佳拟合。We have designed a data acquisition system for use with a RV2 rotational viscosimeter manufactured by Haake of West Germany. The system is based on an IBM-PC and we have designed the A/D interface and software. All information can be displayed in Chinese. Viscosity measurement, data acquisition, printing and curve drawing are implemented automatically. A Spline function—Bezier method is used to optimize the curve fitting of viscosity curves.
