Firstly, the related parameters are distributed periodically in the falling film and their periods all equal to that of vacillation of fishing vessel. Secondly, the film tangent and radial velocity components are not zero because of vacillating additional inertia forces and furthermore, in one vacillation period, most parameters are distributed quite regularly in the tangent and radial directions. Thirdly, when other parameters are kept constant, the falling film absorption is enhanced if the amplitude or the period of vacillation is moderately decreased and this result conforms to the theoretical qualitative analysis. Finally, falling film absorption changes with the solution parameters at inlet and system pressure and the change trend is very similar to what happened in the static tube.

首先，降膜内相关参数分布具有周期性且周期等于摇摆振动周期；其次，摇摆附加惯性力使液膜沿吸收管周向和径向流速不为零，而且单位摇摆周期内各参数沿周向和管长方向分布比较规律；再次，当其他参数一定时，适当减小摇摆幅度和摇摆周期，液膜吸收能力将增强，这与理论定性分析相当吻合；最后，改变溶液入口参数及吸收压力，相应的吸收情况有所改变，其趋势与静止状态下的降膜吸收非常一致。
