Evaporation is the phase transition process that plays a significant role in many spheres of life and science. Volatilization of hazardous materials, pesticides, petroleum spills, etc., impacts the environment and biosphere. Predicting evaporation fluxes under specific environmental conditions is challenging from theoretical and empirical points of view. A new practical method for estimating fluxes is proposed based on our experimental results and previously published data. It is demonstrated that some parameters in theoretical equations for near-equilibrium evaporation can be estimated from experiments, and these formulas can be exploited to predict steady-state evaporation fluxes in the air in a range of 8 orders of magnitude based on a single experiment carried out for nontoxic volatile compounds.
蒸发是一种相变过程，在生活和科学的许多领域都起着重要作用。有害物质、农药、石油泄漏等的挥发会对环境和生物圈产生影响。从理论和经验的角度来看，预测特定环境条件下的蒸发通量具有挑战性。基于我们的实验结果和先前发表的数据，提出了一种估算通量的新实用方法。结果表明，近平衡蒸发理论方程中的一些参数可以通过实验估算，并且基于对无毒挥发性化合物进行的单次实验，这些公式可用于预测空气中8个数量级范围内的稳态蒸发通量。
