  3. The result shows that 1 ) formation coefficient is a main factor. 2 ) boundary and formation heterogeneity have much effect. 3 ) water producing gas wells should be produced reasonably according to gas production policy with water controlling technique so as to avoid watered out. 4 ) with increase of non - darcy flow coefficient, gas well productivity decreases. 5 ) in the process of gas well production, formation energy should be used reasonably. 6 ) when skin factor increases from 0 to 6, its open - flow capacity is 60 % - 70 % of that without pollution

    研究表明：地層系數是影響氣井產能的主要因素；邊界和地層非均質對氣井產能影響很大；對于產水氣井，應嚴格按照控水采氣技術政策合理開采，避免水淹；隨著非達西流系數的增大，氣井產能不斷降低；在氣井的生產過程中，必須合理利用地層能量；當表皮系數由0增加到6時，其無阻流量為不受污染時的60 % ~ 70 % 。
  4. In order to study effects of various factors on gas well productivity, this paper takes changqing gas field as an example and uses gas reservoir engineering and numerical simulation methods to qualify effect of different factors on absolute open - flow capacity in different reservoirs in respect of formation coefficient, water production, non - darcy flow coefficient, formation pressure and skin factor

    摘要影響氣井產能的因素多種多樣，為了具體描述各因素對產能的影響，以長慶氣田為例，利用氣藏工程和數值模擬方法，從地層系數、產水、非達西流系數、地層壓力、表皮系數等幾個方面定量分析了各因素對不同儲層條件下氣井絕對無阻流量的影響程度。
  5. All of the results indicated the turbulent boundary layer had been turned into the laminar layer. the skin friction coefficient drops rapidly. this result not only proved the phenomenon of reverse transition had occurred, but also showed that this condition was drag - reducing condition

    實驗結果表明板面附近的流動已由湍流流動轉變為層流流動，同時平板表面的摩擦系數較沒有溫度梯度時有大幅度下降，不僅證明了邊界層逆轉捩現象的存在，也說明了這種條件起到了減阻的效果。
  6. Behavior and mechanism of concrete filled double - skin steel tubular ( cfdst ) beam - columns subjected to monotonic or cyclic loading were investigated. two kinds of cfdst section tubes were studied in this paper, that is, the outer steel tubes are circular hollow sections ( chs ) or square hollow sections ( shs ), while all the inner steel tubes are chs. based on systematic parameter analysis, simplified models were derived to predict the load - carrying capacities of the composite members, and simplified moment - curvature and lateral load - lateral deflection hysteretic models, as well as ductility coefficient were suggested

    本文從理論和試驗兩個方面較系統地研究了圓、方中空夾層鋼管混凝土構件在單調加載（包括軸壓、純彎、壓彎荷載）下的力學性能和工作機理，以及其在往復荷載作用下的滯回性能，並在參數分析的基礎上，提出了圓、方中空夾層鋼管混凝土軸壓、純彎和壓彎構件承載力的實用計算方法和彎矩-曲率、荷載-位移滯回關系模型及延性系數的確定方法。
