( 2 ) sedimentation cycle study method and technology using wavelet time frequency analysis theory is mostly studied and exploited ( 2 )重点研究和开发了利用时频分析研究沉积旋回的方法和技术。
2.
Theory model and practical test all indicate that sedimentation cycle study in wavelet time frequency domain is feasible . a power tool is provided to sequence stratigraphy application for oil & gas exploration and exploitation 首次提出在小波时频域内研究沉积旋回，它为层序地层学研究提供了一个强有力的工具。
