Advanced mathematical technologies, especially the newly developed wavelet transform and the frame theory, provide a solid foundation for such an effort. the ray - theory based beam - summation method, such as the complex source - generated beam and the gaussian beam methods, and the local phase - space domain ( beamlet domain ) wave field extrapolation methods employing windowed fourier transform ( wft ) or wavelet transform are proposed consequently
基於射線理論的高頻漸近射束(復射束、高斯射束)疊加方法,以窗口富里葉變換( wft )以及小波變換為基礎的局部相位-空間域(小波束域)波場外推方法等相繼產生。In the study of the lagrange stability of impact motion, we give some conditions of the bouncing solution of the asymptotically linear equation which is bounded or unbounded. outside of a large disc, using the symplectic transformation of the hamilton system to estimate the iteration of the successor map. applying the moser ' s small twist theorem, we get the invariant curves and then give the proof of the bouncing solutions which is bounded
在碰撞運動的lagrange穩定性的討論中,給出了漸近線性方程碰撞解有界或無界的條件,在充分大的圓盤外,通過hamilton系統的辛坐標變換的角度平均來估計后繼映射的迭代,應用moser小扭轉定理得到不變曲線從而給出在一定條件下碰撞解有界的證明,碰撞解無界性的證明將採用直接估計后繼映射的方法給出。Asymptotic ray theory
