  1. It also explain that the correlation between ssta of kuroshio and the change of wind field in equaroral mid - pacific is results of air - sea interaction ; however, when time comes into summer, the instance status of ocean is different from the last winter to next early springtime, the sea surface temperature turn into the definitive factor, so the increase of heat flux in may to jun month which is realized by absorbing more heat from the sun radiation results in the decrease of sst in kuroshio in the season of jun - jul. finally, during the aug to dec season of next year, the sst of kuroshio is increasing again

    最後分析了黑潮海溫與夏季東亞大氣環流及我國降水的時滯關系，發現：當前冬黑潮區域海溫異常偏高時，後期夏季亞洲低壓的強度減弱，西北太平洋副熱帶高壓強度加強，而且位置西伸、偏北，梅雨鋒位置偏南，長江中下游地區降水偏多，北太平洋冬季海域的海溫分佈呈+ 、 - 、 +趨勢（順序為赤道中東太平洋、西北太平洋、我國近海） ；反之亦然。
  2. Numerical simulation by cfd was carried out to understand the hot current behavior in a tunnel with longitudinal ventilation. it becomes clear that fire source modeling is very important because the hot current behavior is strongly affected by the fire source position and is sensitive to methods in the modeling of the fire source. the flame area which has developed from the fire source is an area of chemical reaction caused by combustion. even if grids in the vicinity of the fire source are made fine, it was difficult to simulate the heat generation area with consideration to this chemical reaction through using a method for setting the heat release rate simply on the fire source surface. therefore, we proposed a method adopting the knowledge on flame shape under the longitudinal ventilation and incorporating it into numerical simulation and it showed a good agreement with the experimental results. it was shown through experiments in a tunnel with longitudinal ventilation that the hot current developed toward the tunnel center downwind from the fire source near a wall. the cause was investigated by numerical simulation and it became clear from the results that the spiral air by the fire plume created a vortex in the crevice between the wall and the plume

    運用cfd進行數字模擬，以了解縱向通風隧道內熱煙氣流的特性.通過模擬發現對火源進行模擬非常重要，熱煙氣流特性受火源位置的影響很大，並且對火源模擬方法很敏感.火源生成的火焰區是燃燒引起的化學反應區域.即使火源附近的木垛排列完好，也很難在考慮這些化學反應條件下模擬熱生成區域.建議考慮縱向通風隧道內火焰形狀並對它進行數字模擬.模擬結果與試驗結果非常吻合.試驗證明，在縱向通風隧道內，熱煙氣流從靠近墻體火源處順風向隧道中心蔓延.數字模擬結果發現，火災羽流造成的螺旋上升空氣會在墻體和羽流之間形成一個渦流區
