圆管导热系数测试方法研究

The study of determine method of conductive c oefficientsfor cycle pipe

本文阐述了稳态法测试圆管导热系数的原理,分析了常用“圆管法”存在的主要问题,提出了新的相对较简易的测试方法,分析了新方法测试的准确性,同时提出了使用新方法时需要注意的关键问题,在圆管导热系数测试工作中具有一定的指导意义。

The principles was expatiated for the determine methed of conductive coefficients for cycle pipe in steady phase, the primary problems was analyzed for usual method, the veracity of new testing method was valued, and at the same time, the key issues were put forward when using the new method. All these above may have some guideline meaning for the detemaination of conductive coefficients for cycle pipe.
