摇摆振动 meaning in English

rocking oscillation
rocking vibration
wagging vibration

An experimental apparatus of falling film absorption in a vacillating is set up to check the reliability of theoretical model and to have a deep understanding of heat and transfer of practical falling film absorption ; falling film absorption with tfe / nmp solution in a static vertical tube and that in a vacillating tube are investigated respectively
为验证理论模型的可靠性并进一步深入了解实际摇摆降膜吸收过程中热、质传递规律，自建了摇摆振动单管吸收试验台；分别对静止和摇摆状态下tfe / nmp垂直管内降膜吸收进行实验研究。
The experiment results show that when other initial parameters are kept constant , the heat and mass transfer of falling film absorption under the condition of normal vacillation of fishing vessels is better than that in static status ; the amplitude and period of vacillation directly influence the performance of the absorber and an adequate decrease of vacillation period or vacillation amplitude is beneficial to the absorption performance
实验结果表明，当其他初始参数一定时，在渔船常见的摇摆振动条件下，降膜吸收器的热、质传递优于静态下的情形；摇摆振动频率和幅度直接影响降膜吸收性能，适当减小摇摆周期或摇摆幅度均有利于提高降膜吸收性能。
