文章介绍了一种基于非稳态导热乘积法的松散煤体导温系数测试方法,设计了松散煤体导温系数测试系统,介绍了该系统的工作原理、组成结构、处理软件的设计。最后对系统进行了误差分析。该系统实现了计算机自动采集和处理数据,解决了实验装置热流损失对测量误差影响过大的问题,满足了测试要求。

The paper introduced a test method of thermal diffusivity of loose coal based on unsteady- state heat conduction multiplication-method, designed a measurement system for thermal diffusivity of loose coal, expounded working principle, composing structure and design of treatment software of the system. Finally, it analyzed error of the system. The system realized automatic data collection and processing, and solved the problem that measurement is excessive caused by experimental device heat loss. It satisfied for test requirements.
