摘要
本文介绍的仪器采用蒸汽喷射加热，百分表显示数据，可对不同材料制做的样管置换测试，使本项实验的测试结果和教学效果得到显著改善。
The analyzer presented in this paper uses steam injection to heat and centigrade scale to display data and can be used to conduct displacement test for sample tubes made of different materials. As aresult, this experiment has a remarkable improvement in testing and teaching results.
