英文摘要： This project will combine the demand of the information field and methods in mathematics，carry out the analytical research on deep oceanic internal wave models and establish the deep oceanic internal waves detection model, so that the analytic results can serve the remote sensing detection of deep oceanic internal waves better. (1)We will discuss the integrability of internal wave BO model in continuous stratified deep ocean and explore the methods for its analytic solution.We will also analyze the propagation characteristics of deep oceanic internal waves and the effect of marine environments on the propagation of deep oceanic internal waves.(2)We will analyze the physical background related to NLS model, discuss the relationship between nonlinear and dispersion effects and then solve the analytic solution of NLS model with Darboux transformation and its expansion, and analyze the propagation properties of oceanic internal waves.(3)Combining the field test and remote sensing data, we will solve the models of internal waves in finite water depth analytically and discuss the applicable condition and adaptability of the models in deep ocean. What's more, we will modify and generalize the models to adapt to the description of deep oceanic internal waves.(4)We will construct models for deep oceanic internal wave detection with the analytic results and internal wave remote sensing imaging mechanism. Using the remote sensing images of internal waves,its parameters will be inversed and propagation regularity in relevant oceanic area will be obtained and the analysis will be given comparing with the field test data. The results can provide basis for the prediction of deep oceanic internal waves.
