摘　　要：对土壤中的水分含量测定过程中烘干时长,烘干温度及称量方法进行探究,通过对不同水分含量的土壤烘干时长进行探究,以期对土壤烘干时长得出实验指导时长,避免盲目重复烘干实验步骤或延长烘干时间;通过提高烘干温度,探究烘干温度与干燥时长的关系,以期提高实验效率,对土壤中水分含量标准样品采用手动称量法及自动称量法所需时长及准确性进行探究,力求在保证准确性的前提下,优化实验方法,提高实验室运转效率。The drying duration,drying temperature and weighing methods in the determination of moisture content in soil are explored.By investigating the drying duration of soil with different moisture contents,an experimental guiding duration for soil drying is expected to be obtained to avoid blindly repeating the drying experiment steps or extending the drying time.By increasing the drying temperature,the relationship between the drying temperature and the drying duration is explored to improve the experimental efficiency.The duration and accuracy required for the manual weighing method and the automatic weighing method for the standard samples of moisture content in soil are investigated.Under the premise of ensuring accuracy,efforts are made to optimize the experimental method and improve the operational efficiency of the laboratory.

关 键 词：水分含量 烘干时长 烘干温度 称量方法
