The author summarizes the current situation of the fine structure in the Nansha sea area. First of all, we introduce the first international or domestic research methods used in the research, including the most basic methods of CTD data quality control, buoyancy frequency calculation, dispersion relation and wave function calculation, fine structure probability distribution hypothesis testing, Wave detection method, spectral calculation of the tide difference method. Then summarize the research results (some of which were first published), including the classification of buoyancy frequency in the Nansha sea area and its variation with the region and season; the dispersion relation and the wave function of the internal wave; the fine structure and its relationship with the internal wave The non-Gaussian probability distribution of fine structure; vertical wavenumber spectrum characteristics and its change with season, region and water layer; frequency characteristics; Cox number and its probability distribution; Finally, the future research direction is prospected.
