无旋条件 meaning in Chinese

condition of irrotationality

Subsequently , the waves induced forces and their driven effects on currents are studied in detail . in the discussion of the effects of currents on waves , according to the wave radiation theory and the law of wave action conservation , the equivalence of none vorticity condition of the vector of wave number in constant wave field and fermat theory is testified . the dynamic and kinematics effects of background currents on waves are introduced concisely
在流对浪的作用讨论中，依据波动的射线理论和由变分原理导出的波作用量守恒定律，阐明了稳定波场波数矢量的无旋条件与费马原理的等价性，扼要讨论了背景流场影响海浪的运动学效应和动力学效应，首次指出水位(包括天文潮位与风暴潮位)变化对海浪成长与消衰的影响，为流浪潮联合数值模式的发展提供必要的理论依据。
