convection current 對流;【電學】運流。

Over ages , hot convection currents in this sea , as well as gravitational forces , move the plates and their superimposed continents and ocean basins , tearing them apart and rearranging them like pieces of a giant jigsaw puzzle 隨著歲月流逝,海中熱對流及重力移動板塊及覆蓋在上面的大陸塊和海洋盆地,將它們撕裂再重新組合,如大拼圖游戲的碎片。

The spacing between each sheet of glass is important - if it is too narrow , the insulation effect will be poor ; if it too wide , convection currents may encouraged , which increase heat transfer 每片玻璃之間的距離是非常重要的? ?如果間距太小,保溫隔熱性能就很差;間距太大,對流增強,熱傳遞增多。

Hot water is likewise less dense than cold water and rises , causing convection currents which transport energy 熱水是同樣密度較低,比冷水上升,造成對流電流,其中運輸能源。

The ends of the tubular furnace are closed to minimize convection currents inside the furnace 把管式爐的前后端蓋緊,是爐內的對流減少到最低限度。
