提出了一种计算高效、严格的预测大气无机气溶胶物理状态和组成的热力学模型。该模型的主要特点之一是实现了多组分盐粒子的相互潮解，降低了气溶胶相的潮解点。该模式用于检查四种类型对流层气溶胶（海洋、城市、偏远大陆和非城市大陆）的行为，并将结果与目前使用的另外两种模式的预测结果进行了比较。三种模型的结果基本一致。差异主要出现在相互潮解的湿度区域，新模型预测了水的存在，而其他两个模型则没有。指出了不同气溶胶类型在行为（形态和吸水性能）上的差异。新模型还需要相当少的CPU时间，并且总是显示出稳定性和鲁棒收敛性。
A computationally efficient and rigorous thermodynamic model that predicts the physical state and composition of inorganic atmospheric aerosol is presented. One of the main features of the model is the implementation of mutual deliquescence of multicomponent salt particles, which lowers the deliquescence point of the aerosol phase.The model is used to examine the behavior of four types of tropospheric aerosol (marine, urban, remote continental and non-urban continental), and the results are compared with the predictions of two other models currently in use. The results of all three models were generally in good agreement. Differences were found primarily in the mutual deliquescence humidity regions, where the new model predicted the existence of water, and the other two did not. Differences in the behavior (speciation and water absorbing properties) between the aerosol types are pointed out. The new model also needed considerably less CPU time, and always shows stability and robust convergence.
