摘　　要：根据密度计的工作和检定原理,介绍各种密度检定液的配制方法及注意事项。针对硫酸氢乙酯检定液难以配制问题,着重介绍了检定液的配制过程,通过对不同浓度酒精液配制的硫酸氢乙酯校准密度计的比较实验,说明了不同体积分数酒精液配制的硫酸氢乙酯对校准结果的影响。According to work and verification principle of densitometer,preparing methods of the density calibration fluid and precautions were introduced. Preparation process of the test liquid was mainly introuduced for its preparation questions of ethyl hydrogen sulfate. Impact of different concentration ethyl alcohol liquid hydrogen prepared with different volume fraction ethyl alcohol on calibration results was explained through the comparison of calibration experiment.
