摘　　要：冰的熔解热实验中原测温方法为人工定时测量,采样点有限且采样时刻不准确,由此造成测量误差,导致后续数据处理极其烦琐。为克服人工测量的不足,提出一种新的测温方法。该方法借助自主搭建的以单片机为核心的智能定时测温平台,实现对温度数据自动定时记录、存储及处理。相比之前的测温方法,该方法具有温度数据记录实时性好、采样点数目多、数据处理简便等优势。Originally,in the experiment of measuring the fusion heat of ice,the temperature is measured by manual timing,hence,the number of sampling points is limited and the sampling time is not accurate,which results in measurement errors. Also,data processing of the original method is extremely tedious. To solve these problems,a novel thermometry method is proposed. This method depends on a self-built intelligent timing thermometry platform. The core part of this platform is a single-chip microcomputer which realizes automatic timely recording,storing and performing of the temperature data. Compared to the former thermometry method,this method has the advantages of better real-time recording of data,more number of sampling point as well as easier in data processing.
