摘要
介绍了基于瞬态热流法的导温系数快速测定系统,针对测试装置开发了专门的数据采集、处理和控制软件,该软件可以进行过程监控,高频采集数据并进行误差分析处理。用该装置测试了几种固体散状物料的导温系数,测试结果表明该系统稳定性高,误差小,有一定的工业应用价值。
A set of apparatus for determining thermal diffusivity based on the theory of transient heat-transfer is introduced, in which a software system for data collection and data processing is developed. The software system can be used for process monitoring, data collecting in high frequency and error analysis. Several granular materials＇ thermal diffusivities are determined. The results indicate that the system has high stability and small error. It possesses industry application value.
