北大西洋洛克尔海槽东北部水深约１ ０００ ～１ ０００ ｍ 处有两个大型沉积物波发育区。波长１ ～２ ｋｍ ，波高１８ ～２０ ｍ ，分布面积分别为３５０ ｋｍ ２ 与２０ ｋｍ ２ 。沉积物波向上坡迁移，内部包括上攀床形单元、不对称波形单元及正弦波形单元。前人提出的大区沉积物波挪威海底层水溢流成因及小区沉积物 Ｌｅｅ 波迁移模式都存在许多问题。根据古气候及古洋流资料，研究区内沉积物波各单元形成时具备内波形成的条件，内波的发育与等深流的活动密切相关。运用内波理论可对沉积物波各构成单元作出合理的水动力学解释，研究区内两列同向内波的叠加、单列内波及内驻波先后作用海底，可分别形成大型上攀床形、不对称波形及正弦波形单元。
There are two large sediment wave development zones in the northeastern part of the North Atlantic Loirer Channel at a depth of about 1 000-1 000 m. Wavelength of 1 ~ 2 km, wave height 18 ~ 20 m, the distribution area of 350 km 2 and 20 km 2. Sediment waves migrate upward, including the upper bed-shaped element, the asymmetric waveform unit and the sinusoidal waveform unit. The predecessors proposed that there are many problems in the sediment waves in the sea floor of Norway and the Lee wave migration pattern in the sediments of the area. Based on paleoclimate and paleocurrent data, it is found that the formation of internal waves in the sedimentary waves in the study area has the condition of internal wave formation. The development of internal waves is closely related to the activities of the isobath. By using the theory of internal waves, reasonable hydrodynamic explanation can be made for each component of the sediment wave. The superposition of two columns of the same direction and the inward waves in the region is studied. The single column of internal waves and the internal standing wave function successively on the sea floor, , Asymmetrical waveforms and sine wave units.
