  1. In this thesis hydraulic experimental studies and theoretical analyses on the vortex - flow drop shaft were conduced and the following results were accomplished : ( 1 ) in the model test some hydraulic characteristics including the shape of air core in the center of the drop shaft, the radial distribution of water flow velocity and the distribution of pressure on the wall of the drop shaft were measured under the condition of high water head above 250m and large discharge above 1400m3 / s. ( 2 ) a kind of computational method for the spiral water flow in the air core region of drop shaft was discussed and applied and the results agree the experimental data well. ( 3 ) the total ratio of energy dissipation in the drop shaft can reach 90 % and the energy dissipation in every region was discussed quantitatively

    本文通過試驗研究與理論分析對旋流式豎井泄洪洞應用於高水頭、大泄流量情況時存在的一些水力學問題進行了研究和探討，取得以下主要成果：一、結合小灣工程導流洞改建，對高水頭（ 252m ） 、大泄流量（ 1400m ~ 3 s ）條件下旋流式豎井中的水流運動特徵進行了比較全面的測量，包括空腔形態、徑向流速分佈及井壁壓強等；二、提出了豎井空腔段螺旋水流水力計算方法，其計算結果與實測值吻合良好；三、利用試驗與計算結果，對旋流式豎井的消能機理進行了探討，對豎井各部分的消能能力有了總體認識；四、對豎井下部消力井的合理井深進行了優化試驗研究，發現消力井合理深度為0 . 9d左右；五、通過試驗研究，歸納出豎井水流總摻氣量估算方法，為導流洞排氣方案的設計提供了參考依據；六、在高水頭、大流量條件下，豎井空腔段下部流速很高，盡管水流螺旋運動引起的離心力可以確保井壁壓強保持正壓，但空化數依然較低，因此豎井的空化空蝕始終是工程界關注的重大問題。
  2. Warning : reinspection of t & p relief valve : temperature and pressure relief valves should be inspected at least once every three years by a licensed plumbing contractor or authorized inspection agency, to ensure that the product has not been affected by corrosive water conditions and to ensure that the valve and discharge line have not been altered or tampered with illegally

    警告：重新檢查溫度壓力安全閥：溫度壓力安全閥每年應該由有資格證書的管道承包商或經過批準的檢查機構來至少檢查一次，以確保這種產品不會受到腐蝕性水的影響，確保閥門和排泄管道不會被不合理的更換或損壞。
  3. The results indicate that ( 1 ) faults are predominant pathways for oil and gas migration in the dina 2 struc - ture ; ( 2 ) the pressure released zones are available for oil and gas migration ; ( 3 ) capillary and buoyancy play an important role in sandstone with similar permeability ; ( 4 ) hydrocarbon migrates always along the predominant pathways, such as faults and associated sandstone in both sides ; ( 5 ) pathways of oil and gas migration have the nature of succession, such as oil driving water and following gas driving oil

    通過模擬實驗，揭示： （ 1 ）斷層是迪那2構造中油氣運移的主要通道； （ 2 ）泄壓區是油氣運移的有利指向區； （ 3 ）毛管力及浮力在滲透性相近的砂巖中起重要作用； （ 4 ）油氣咩是選擇優勢通道運移，在沿斷層運移的同時，也向兩側砂體中擴散； （ 5 ）油驅水之後的氣驅油運移通道具有繼承性的特點。
