英文摘要：

This paper is concerned with the development of calculation models for falling-film absorption in recent years, especially for vertical tube absorber and plate case. In the order of the theory model＇s improvement, the general review of the assumptions, governing equations, boundary conditions, and solution methods for the models are given, and also the discussion of the model＇s advantage and disadvantage by their calculation result. Finally, the way of optimization the model of calculation in falling-film absorption is discussed.
