  1. For a soil or rock of water - lacked, a heat transfer theoretical model is developed, which is a steady or unsteady, the results show that reservoir temperature, thermal diffusion coefficient, inlet temperature, flow rate of and run time of ground source heat pumps have an effect directly on heat transfer process of dhe. it can deduce that intermit running is favorable for this type of soils and rocks

    對于貧含水地下巖土層建立了穩態與非穩態傳熱的理論模型，分析結果表明，巖土層的熱儲溫度、導溫系數、埋地換熱器進水溫度、流量以及地源熱泵系統的運行時間或開停機比，都對埋地換熱器的傳熱過程產生直接影響，可以推斷，對于該類型巖土層的地源熱泵系統，採用間歇運行將是有利的。
  2. The results prove that : ( 1 ) when the mach number of the flow at the exit increases, the total pressure recovery decreases, and the circular steady total pressure distortion coefficient, turbulence intensity and synthesis distortion increase

    研究結果表明： （ 1 ）地面工作狀態下，隨著出口馬赫數的增加，蛇形進氣道出口截面的總壓恢復系數不斷下降，而穩態周向畸變指數、紊流度和綜合畸變指數均上升，穩態徑向畸變指數變化不大。
  3. In this paper i was in virtue of the fluent software, set up the geometrical model of jin ’ ao mansion and adjacent buildings, used non - equilibrium wall functions to deal with the problem which come from the near wall, used realizable k - turbulent model to simulate the steady flow around 3d high - rise buildings, we can get the distribution of mean wind pressure coefficient of the surface of jin ’ ao mansion and five aerodynamics components. they were compared with the data from the wind tunnel test, we found out the distance between the result of the wind tunnel test and numerical simulation in the acceptable range

    本文以fluent軟體為平臺，建立金奧大廈及其周邊建築的計算幾何模型，近壁區採用非平衡壁面函數法處理，運用基於雷諾時均的realizablek -湍流模型進行高層建築三維定常風場數值模擬，獲得金奧大廈表面時均風壓系數分佈及基底五分量氣動力，並和風洞測壓試驗的結果及風壓系數積分計算的基底五分量氣動力相比較，發現兩者之間的差異在可接受的范圍之內。
  4. Other content in this paper is the design and investigation of spiral inlet port. the geometries that compose intake port have been repeatedly when intake port scheme was designed. the intake port scheme has been carried out steady - flow test. the experiment data has been analyzed and investigated, then the performance of inlet port has been estimated by the fluid coefficient and the whirl ratio. at last, the spiral inlet port scheme has been selected based on matching relation of the factors of combustion system. in addition, how to " intake port synthesis performance coefficienf ' evaluate engine intake port has been discussed

    本文的另一項內容是螺旋進氣道的設計和研究。通過對進氣道的幾個主要結構參數進行反復修改擬定進氣道方案，並對其進行穩流試驗，分析和研究試驗數據，利用流通系數、渦流比進行進氣道性能評估，根據燃燒系統要素的匹配關系，確定了兩種螺旋進氣道方案。另外，本文探討了「進氣道綜合性能系數」對發動機渦流進氣道性能的評估能力。
