“燃烧热测定”教学实验的改进

本文介绍了在燃烧热的测定实验中采用双孔带槽模底,单、双股燃烧丝相结合的挂样片法,代替单孔或无孔模底,单股燃烧丝接触样片法,以及压片操作技法。四年的实践表明,这种实验方法大大提高了实验的成功率,缩短了实验操作时间。

TEACHING AND STUDING TEST OF IMPROVENT FOR COMBUSTION HEAT DETERMINATION

In the test,the test of combustion heat determination use pattern plate with double hole and groove and nathode of put into sample for the combustionsilk yam one and be combined withe two.It replace pattern plate of the one hole or not,and mathod of the combustion silk yam is one come into contact with sanple well and well technology imoprove ment of the squeeze sample.The mathod practice for four year it is indicate the rate of test success enhancement and test time is short,in this paper.
