  1. Through the special studies on impacts to atomizing and humidifying effect from such factors as the firing pin type, centrifugal structure, higher spraying pressure, less aperture, initial water temperature and original state of the air, some conclusions are obtained, such as : the centrifugal nozzle with firing pin type, high pressure and little aperture has bigger air eddy and atomizing angle. the spaying liquid has high velocity. the droplet is small, and the heat and mass transfer velocity is high

    通過對撞針型結構、離心結構、較高的噴水壓力、較小的噴嘴徑、噴水初溫及待加濕空氣初狀態對霧化加濕效果的作用原理的重點分析,得到:撞針型高壓小徑離心噴嘴具有較大的空氣渦與霧化角,噴出的液體速高、液滴小、水與空氣傳熱傳質速率高,撞針型結構提高了霧化加濕效率,高壓小徑的特點為霧化加濕提供了較大的能,而噴水初溫的升高會減小水的粘性力和面張力,從而優化加濕效果。
  2. When soil antecedent condition is dry and the initial rainfall intensity is high, peak surface runoff also considerably lag behind that of rainfall, because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response, only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism, and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h, indicating the existing of macropores and pipe flow in cultivated layer

    2 )耕作制下紫色土的產主要機制是: 1 )當雨前土壤含水未達到飽和狀態時,面產起始時間有明顯滯后現象,這與紫色土的快吸水性和較多非毛管隙密切相關;當雨前土壤較乾燥,降雨初期雨強較大時,易形成臨時相對不透水層,面產峰也有明顯滯后現象。 2 )面徑的產主要是超滲產,當土壤達到飽和狀態后,有四川大學博士學位論文小部分回歸發生,但主要是飽和超滲產發生,因為紫色土的相對不透水層和其它透水障礙層不明顯。 3 )壤中主要是飽和產,與降雨過程有明顯的滯后,而且雨停后的壤中歷時與降雨特徵無關。
  3. The fluxion model of gas and the gas pressure formula were decided in the surrounding of bore wall firstly, and according to the relation of gas content and gas pressure, the theory calculation formula of gas loss quantity was deduced, and finally, the revision method of original coal gas pressure was brought

    摘要首先確定了壁周圍瓦斯的動模型及瓦斯壓力,進而根據瓦斯含與瓦斯壓力的關系,推導出了瓦斯損失的理論計算公,最後提出了瓦斯壓力的修正方法。
  4. Then the thermal visualizations of jet impingement cooling with single or double row holes inside semi - enclosed ribbed channel are measured by using infrared camera and the effects of flow and geometry parameters on convective heat coefficients are obtained. the results show that : the impingement cooling effectiveness of ribbed surface is affected greatly by the jet - to - surface spacing, and the best effectiveness is achieved under the jet - to - surface spacing equals to 1. the correlation formulas of impingement heat transfer characteristics to the parameters are finally concluded and in good agree with the experiment data
