( 3 )通過對空氣介質中簡易地下滴灌的微孔毛管試驗研究發現: 60m管長的毛管平均壓力水頭的位置基本上在距第一孔口的有效管長40 - 45的地方;大部分水頭損失發生在毛管的前半部分;壓力均勻度隨孔徑的增大而減小,但與初始工作水頭關系不密切;在1 . 5m以下的工作壓力下運行,沿程出流均勻度隨孔徑的增大而降低,當孔徑不大於1 . 0mm時,灌水均勻度可以達到60以上;當孔徑大於等於1 . 2mm時,灌水均勻度低於50 。Eight trapezoid labyrinth flow - channels are designed through modification to the cell dimension and the number of flow cells based on the parameterized structural design. integral emitter prototypes combining exterior hull and exterior flow - channel are built using rapid prototyping technique, and structural dimension of those flow - channel are measured by optical microscope, the measuring results showed that the design can completely meet the requirement of emitter accuracy
文中以參數化的設計思想,通過改變梯形迷宮流道單元尺寸和單元數設計了8種梯形迷宮流道,採用快速成形技術製作出外管與內迷宮流道一體化的滴頭原型;利用最小標注尺寸為50nm的光學顯微系統對滴頭流道結構尺寸進行了測量,分析結果顯示流道尺寸精度完全滿足滴頭的製作要求。First, controls and restrictions on the flow of money can never be watertight, and they risk creating market distortions and, worse still, financial repression
第一,任何資金流動管制措施均不可能做到全無罅隙,滴水不漏,這樣可能造成市場扭曲,甚至遏抑市場發展。Characteristics of flow resistance of pin finned drop - shaped tube at different attack angles
流體攻角對滴形釘頭管流體阻力特性的影響With the in - built drip irrigation belt and thin wall chip irrigation belt taken as examples, the flow rate distribution and hydraulic losses of drippers along capillary tubes at different inlet pressures were measured under the conditions of horizontal slope and slope gradients of 0. 5 % and 1 %, then the uniformity of capillary tubes was calculated at different slope gradients and pressures in consideration of the manufacture deviation of drippers
摘要以內鑲式滴灌帶和薄壁滴灌帶為研究對象,測定了平坡、 0 . 5 %坡度和1 %坡度時,不同入口壓力下滴頭沿毛管的流量分佈和水力損失,並結合滴頭的製造偏差,計算得出不同坡度和壓力條件下滴灌毛管的均勻度。( 3 ) based on the experiments data, it has been found that if the emitter discharge of sdi was little, the depth of pipe buried should be shallow, and the distance between two micro holes should be chosen to equal or close the distance between two lateral pipes, if the emitter discharge of sdi was great, the pipe may be buried deeper, and the distance between two micro holes could be greater than the distance between two lateral pipes
根據一維土柱近似的濕潤輪廓線初步選定了工程設計參數。在地下滴灌灌水器出流量較小情況下,埋深應淺,孔距應選擇和毛管間距相等或接近;出流量大時,埋深可深,孔距大於毛管間距仍可獲得較均勻的土壤水分分佈。This reflux of air could contain contaminated droplets of sewage present in the soil stack. the contaminated droplets could deposit virus on various surfaces, such as the floor mat, towels and other bathroom equipment
