摘要
传统的燃烧热的测定实验存在着实验操作复杂,成功率低,数据误差大等问题,针对这些问题尝试将科研用发热量测定仪引入基础实验,同时增加了面粉的发热量测定这一实验环节,大大缩短了实验时间,提高了实验成功率和测量结果的准确度,拓展了该实验的实用性。
The traditional determination of combustion heat has several problems,such as the long experimental time,the low success rate and the greater measurement errors. Focusing on these problems,the microcomputer fully automatic calorimeter was introduced into the basic chemistry experiment. At the same time,the instrument was used to determine the calorific value of flour. These improvements shorten the experimental time,improved the success rate and the accuracy of measurement results,and expanded the applicability.
