  4. This experiment include many contents, in a word, that is summer condition experiment, winter condition experiment > summer - winter transition condition experiment and winter - summer transition condition experiment, furthermore summer condition experiment still include flux changing experiment and winter condition experiment still include thermal balance experiment this article dealt with the data of the test, calculating out energy absorbing ( energy discharging ) of buried pipe in winter condition ( summer condition ), input power of heat pump x heat exchanging of piece buried pipe length x co - efficiency performance ? op ( energy efficiency rate ? er ) and average heat exchanging coefficient ; in additiont this article compares the inlet water temperature and outlet water temperature of underground the first layer and the second layer buried pipe when heat pump was running, the results are that the heat exchanging ability of the second layer buried pipe outgos the first layer buried pipe, and heat exchanging is more stable ; and still analyse earth temperature resuming in the transition season. the results are earth temperature resume fast in the first week when the heat pump runs off

    本文測試內容相當多，概括地說就是四個工況的測試，即夏季製冷工況的測試、冬季供熱工況的測試、夏?冬過渡季測試和冬?夏過渡季測試；另外在夏季工況的測試中還進行了變流量測試，在冬季工況的測試中還進行了熱平衡測試。本文對測試數據進行了處理，計算出了冬（夏）季工況埋管吸（放）熱量、熱泵空調器供熱量（製冷量） 、熱泵空調器輸入功率、埋管單位管長換熱量、供熱性能系數（製冷能效比）和平均傳熱系數等；另外，還比較了熱泵運行時地下一二層埋管進出水溫度變化情形，得出地下二層埋管換熱能力優于地下一層埋管，且換熱很穩定；並分析了過渡季地下一二層埋管溫度恢復情形，得出熱泵系統停機一周內地溫恢復特別快。
  5. While slug structure is leaving from computing domain, the successive disturbance develop in downstream direction, the legs of hair - pin vortex approach the wall continuously and induce vortex structures near the wall. the evolution of this near - wall vortex structures brings the secondary transition to turbulence in the pipe flow

    隨著塞流結構流出計算域，后繼擾動向下游繼續發展，表現為發卡渦的渦腳向壁面不斷貼近，進而誘發近壁渦結構，近壁渦結構的進一步演化促使圓管流動出現二次轉捩，發展到了湍流階段。
  6. Based on these parameters, the present work studies the transition of pipe flow with the different amplitude of psb disturbance. the present work simulates the whole time - space process of the transition from laminar to turbulence and secondary transition phenomenon in pipe flow for the first time. the main structure in pipe flow transition is hair - pin vortex ; the evolution of hair - pin vortex is related with the transition of pipe flow

    在這一組參數下，本文研究了不同擾動幅值的psb擾動作用下圓管流動的轉捩過程，首次給出圓管流動從層流轉捩到湍流的時空演化全過程，發現了圓管流動的二次轉捩現象，並進一步揭示了發卡渦是圓管流動轉捩中的主要結構，流動的轉捩過程與發卡渦的演化直接相關。
