摘要
对有机物燃烧热的测定方法进行了改进。改变点火丝的安装方法,采用高性能量热计,改变氧弹内氧气的压力及燃烧样品的用量,确定了新的测定方法。采用新的测定方法测定萘的燃烧热,测定结果的相对误差为0.05%,相对标准偏差为0.077%。
The method for determining the combustion heat of the organic compounds has been improved, including changing means of fixing firethread, using the super performance calorimeter, changing oxygen pressure in firebox and changing the sample quantity. The new method is determined. The combustion heat of naphthalene was determined according to the new determining method, the relative error of determining result is 0. 05% and the relative standard deviation is 0. 077% .
