本文介绍了由切比雪夫多项式逼近的标准电阻温度公式。对实验数据计算的结果表明,在偏离20℃较大的温域内,该式适于作标准电阻的温度公式。
This article describes the standard resistor temperature equation approximated by the Chebyshev polynomial. The calculation results of the experimental data show that the formula is suitable as a temperature formula of the standard resistance in the temperature range of 20 ° C larger.
