摘要
从多个角度设计实验方案,测量甘油的粘滞系数,对实验结果进行误差分析,指出PHⅢ-型变温落针式粘滞系数实验仪在设计上存在的缺陷,并探讨改进之处。
This paper designed the method of experimental project from several angles. The viscosity of glycerin is measured. Then, it gives the analysis of results. At last, the paper points out the deficiency of the PH-Ⅲ-temperature viscosity experimental instrument, and discusses the improvement.
