摘　　要：通过建立防爆电机绕组温升计算数学模型,阐述了采用电阻法测量不确定度的分析和计算过程。With the development of science and technology, the demand to measuring is more and more strict. It is very important part of measuring temperature on windings for determining the performance of an explosion - proof motors. In this article, it expounds computational process and a- nalysis on uncertainty of measurement with resistivity method based on a mathematical model estab- lished.
