翻译后摘要：海洋潮汐，风应力，Hoa流入和分层的作用在Mururoa泻湖的长期循环进行了研究，通过一个三维模型的敏感性分析。 水更新的时间尺度估计。风应力被证明是占主导地位的强迫。Hoa入流略微增加周转时间，而层结增强了平行于风应力的垂直面运动的影响。模拟周转时间约为100天，当忽略风应力时，周转时间远大于一年。
Abstract. The role of oceanic tide, wind stress, hoa inflow and stratification in the long-term circulation in Mururoa lagoon is investigated using a sensitivity analysis carried out by means of a three-dimensional model. Water renewal time scales are estimated. Wind stress is shown to be the dominant forcing. The hoa inflow slightly increases the turnover time, while stratification enhances the impact of motion in vertical planes parallel to the wind stress. The modelled turnover time is approximately 100 days, and becomes much larger than one year whenever the wind stress is disregarded.
