基于对饱和水汽压的求导，提出湿球温度计算的牛顿迭代法。本法具有迭代速度快、成果精度高以及适用范围广等优点。结合算例指出，由于相对湿度观测值含有较大的舍入误差，由此计算的湿球温度精度相对较低，建议尽量采用水汽压来计算湿球温度。

Based on the saturation vapor pressure function derivative calculation, Newton iteration method was proposed to calculate the wet-bulb temperature, which is with high iteration speed and high precision and wide application. It is found that the wet-bulb temperature calculation precision according to the relative humidity formula was lower than to the vapor pressure formula as the relative humidity observed values have lager rounding errors, and the vapor pressure formula was recommended to calculate the wet-bulb temperature.
