( 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。
Ordos basin is a polycyclic superposition basin that is formed in an earlier geological history and has experienced a longer evolution 鄂尔多斯盆地是一个多旋回叠合型盆地，其形成历史早、演化时间长。
These internal - tide deposits possessed five types of vertical successions and formed rhythmic deposit combinations with cyclicity in the vertical section 它们具有5种垂向沈积层序，在剖面上常形成多旋回韵律性沈积组合。
By analyzing the faulted features , faults have the characteristics of generation , successive , cycle , segment and correlation 通过分析断裂特征，提出了本区断层具有分期性、继承性、旋回性、分段性和相关性的活动规律。
During the upper paleozoic in huabei there were 3 main times of sea level eustacy which caused different deposits in research area 华北晚古生代经历了3次大的海平面升降旋回，不同海侵事件在研究区内留下了不同的沉积纪录。
Why the tropics are so diverse is something of a mystery , but one explanation is called a species pump 热带地区为什么会有如此丰富的物种是个犹如谜一般的问题，但有一种解释叫做“物种泵” （和米兰科维奇冰期旋回理论有关译者） 。
These cyclic sequences may be divided into three types : " deepening " - upward asymmetrical type , " shallowing " - upward asymmetrical type and symmetrical type 运用旋回等时对比法则对短期基准面旋回层序进行等时对比，并建立等时地层格架。
Sequence analysis and isochronous correlation of the short - term base - level cycles in the third oil reservoirs of the yanchang formation in the huachi oil field , ordos basin 鄂尔多斯盆地华池油田延长组3油组短期基准面旋回层序分析与等时对比
In this paper , various types of structure and the relationship between sedimentary dynamic process and strata response of the short cycle sequences is discussed 讨论了短期基准面旋回层序的各种结构类型和沉积动力学过程与地层响应的关系。
In the studying zone , one long term cycle , 6 middle term cycles and 27 short term cycles was identified and correlated . base on the correlation 在非均质模式与油气动用状况分析基础上，研究了基准面旋回对油气动用状况和剩余油分布的控制作用。
