气体热导率测量实验中减少系统误差的一种方法

A Method of Reducing Systematic Error in the Measurement of Gas Thermal Conductivity

在热线法测量干燥空气热导率的实验中,实验数据记录会产生较大系统误差,现通过四种方法对实验数据记录,采用Matlab软件计算和作图分析,探究出最佳的实验数据记录方法,从而最大限度地减少实验数据记录引起的系统误差。

The hot line method of measuring thermal conductivity of dry air experiment,experiment data records will produce bigger system error,through four ways to keep a record of the experimental data using the Matlab software calculation and graphic analysis,to explore the best experimental data recording method,thus minimizing the system error caused by the experimental data.
