单向波动方程 meaning in Chinese
one-way wave equation
Examples
- From 1920s up to now , various techniques and methods for wave field decomposition , propagation and migration / imaging have been well developed , such as the kirchhoff asymptotic method , frequency - wavenumber domain phase - shift and phase - shift - plus - interpolation methods , and the one - way wave equation based phase - screen and generalized screen methods , etc . wave field extrapolation in these methods is implemented based on the expansion of the wave field by sets of basic functions like spatial fourier harmonies , modes , and green ' s functions
自上个世纪二十年代至今，波场分解、传播与偏移成像技术经历了将近一个世纪的发展，形成了多种不同的方法，如kirchhoff波动方程高频近似解方法，频率-波数域的相移( phase - shift )方法和相移-内插( pspi )方法，以及在混合域中基于单向波动方程的相位屏、广义屏方法等。
