As the main flow manner of formation water in deep reservoir, circulated convection current controlled authigenic mineral location and secondary pore distribution.(循環熱對流是深部儲層流體的主要流動方式，它控制著自生礦物在砂層中的析出位置和次生孔隙的分布特征。)

As warm air rises cool air is drawn in to replace it creating a convection current.(熱空氣上升，冷空氣補充取代之，就產生了對流氣流。)

The uncertainties associated with current stellar models lie in the input physics: atomicdata, convection theory, mixing in radiative regions, and mass loss.(當前恒星模型中的不確定性來自于輸入的物理參數：原子數據、對流理論、輻射區的混合和質量丟失。)
