| 摘 要： | 该文分析了燃烧热测定实验常见的失败原因，并针对其中的主要原因，提出了4点改进方法，即改变燃烧丝在片状药品中的状态和位置，改变药片在氧弹内坩埚中的状态，改变氧弹内氧气的压力值和改变点火电流控制转钮的操作方式。同时探讨了改进的机理，实践证明，这些改进措施是行之有效的。

| Abstract: | In the paper, the common causes resulting in failure determination of combustion heat in experiment have been analyzed, and aiming at the principal causes, the improvement in experimental specific means has been presented. The introduced techniques include changing the state of firebox in lamellar sample and the state of the sample in firebox, changing oxygen pressure in firebox and adjusting operation mode of rotating key which controls the electrical current of portfire.The mechanism of improvement has been discussed,and it is found that these means are effective in practice. |
