摘　　要：采用手动法和计时法测定聚苯乙烯(PS)、丙烯腈-丁二烯-苯乙烯共聚物(ABS)的熔体密度,研究了自动法测定熔体流动速率。结果表明,自动法测定PS、ABS的熔体流动速率方便快捷,与手动法比较,其误差小于2%。The test method of automatically timed melt flow rate measurement for ABS and PS was studied, using the melt density data determined by manual method and automatically timed method. Results showed that the precise melt flow rate could be obtained easier by the automatic determination of melt flow rate. Compared with the manual method, the error of the result was less than 2 %.
