摘要
Abstract
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.关键词
