Put forward a new approach which describe the relationship of resistance-temperature conversion for common thermo-resistance in terms of BP networks has the characteristic of non-linear.
利用BP网络具有任意逼近非线性函数和内插值特性，提出一种实现常用热电阻阻值-温度变换的新方法。

Result showed that the thermo decomposition reaction of DH170T had higher resistance, lower reacting rate and longer service life than TR2000.
In this paper, principle and constitute of thermo-resistance detector of integral insulation construction in pipeline are introduced and error in measure is analyzed.
