龍須草能改善紫色土的土壤結構龍須草純種植被和林草立體種植植被能不同程度地降低土壤容重，減少土壤砂粒含量，增加土壤的毛管孔隙度、非毛管孔隙度和孔隙比，以及增加粉粒含量，從而降低土壤分散度，提高土壤團聚性，增加土壤團粒結構數量，改善土壤的透水性，促進良好土壤結構的形成，最終提高土壤的蓄水保肥性能，增強土壤的抗蝕性和抗沖性。Many factors have effect on irrigation uniformity. with the growing of pressure, how is irrigation uniformity of trickle irrigation varying on different condition of the diameter of drip line, the distance of emitters, the length of drip line, the style of emitters, the flux ratio of emitters and the face gradient of little irrigation district. the consequence shows that pressure has puny effect on irrigation uniformity
滴灌系統的灌水均勻度受眾多因素的影響，本文通過毛管的管徑、滴頭間距、毛管的管長、灌水器的類型和灌水器的流量系數不同的情況下，灌水均勻度隨壓力水頭變化模擬結果顯示，壓力水頭對灌水均勻度影響非常小。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流主要機制是： 1 ）當雨前土壤含水量未達到飽和狀態時，表面產流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孔隙密切相關；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表層，表面產流峰也有明顯滯后現象。 2 ）表面徑流的產流方式主要是超滲產流，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流發生，但主要是飽和超滲產流發生，因為紫色土的相對不透水層和其它透水障礙層不明顯。 3 ）壤中流主要是飽和產流，與降雨過程有明顯的滯后，而且雨停后的壤中流產流歷時與降雨特徵無關。On the contrary, the length of drip line, the diameter of drip line, the distance of emitters and the face gradient of little irrigation district have remarkable effect on irrigation uniformity
在田間工程中，毛管長度、毛管的管徑、滴頭間距和地形坡度對灌水均勻度影響非常顯著。In the hillslope, d ( ), c ( ) and k ( ) of soil water have high spatial correlation. d ( ), c ( ) and k ( ) are significant affected by soil water content, capillary pore and sand content bulk density and non - capillary pore aperture are significantly affected on permeability rate. correlation analysis indicates that it is significant correlate
在坡面上，含水量、毛管孔除和砂粒含量對土壤水的擴散率、比水容量和導水率的影響較大;容重和非毛管孔隙對滲透率的影響較大，相關性檢驗達顯著和極顯著水平。On the other hand for four main vegetation typies, which are picea crassifolia, forests sabina przewalskii forests, bushes and pastureland, whose soil permeability function was analyzed from angle of its physics, capacity of water, storing water in it. the results show as follow : permeability function of soil is controlled by quality of soil hole. the quality and quantity of soil hole under picea crassifolia forests are the best, and the permeability also is the best
另外，從土壤物理性質、蓄水量、貯水量等角度對祁連山苔蘚雲杉林、祁連圓柏林、亞高山灌叢林、牧坡草地4種主要植被類型的土壤滲透功能進行分析，結果表明：土壤的滲透功能主要由土壤非毛管孔隙度的質和量決定的，苔蘚雲杉林土壤非毛管孔隙度的質和量最好，它的滲透也最好；雖然亞高山灌叢林的滲透功能次之，但由於它所處的位置和面積大，現實貯水量在祁連山四種主要植被類型中最大。Measuring unsaturated hydraulic characteristic parameters, such as capillary soil water, saturated soil moisture, field moisture, saturated conductivity etc., is not only expensive but also accuracy uncontrolled
測量非飽和帶水力特性參數：毛管上升水、飽和含水率、田間持水率、給水度、飽和滲透系數等，即費時、費力又難以保證試驗精度。The fractal dimension of the mixed forests were lower than the pure forests and grassland, and the soil weight diameter of the mixed forests were higher than the pure forests and grassland, which indicated that the mixed forest had best soil structure property in stability infiltration and water - holding ; the soil total porosity and the soil noncapillary porosity were different greatly between forest types, but the soil capillary porosity had little differ
混交林分分形維數均低於單純林與荒草地，土壤重量平均直徑均高於單純林與荒草坡，說明混交林土壤結構穩定性最好，土壤通透性較好，具有較高的水土保持功能；不同林分類型之間，土壤總孔隙度與非毛管孔隙度差異較大，而毛管孔隙度的差別較小。It was showed that forest with good structure could improve the soil noncapillary porosity and water conversation function, and it was implied that forest with rational structure stored rainfall and surface runoff quickly
表明具有良好結構的林分，可有效改善土壤非毛管孔隙度和滯留貯水功能，從而有效地提高對降雨的快速貯存以及蓄洪與涵養水源作用。Non - aqueous capillary electrophoresis, nace
在非水毛細管電泳These small smokey - black birds fly in flocks and, in flight, look like small anchors due to their short square tail and long narrow wings
桉樹樹皮非常薄，據說耳朵貼著樹干靜心細聽，可聽到樹內的毛細管吸水聲。Based on the theory of shrinkage, capillary force theory, the influence of road concrete additives in common use on surface tension of water is studied, and the results show that the influence of water reducer is very small whereas shrinkage - reducing agent and air entrainer can reduce surface tension of solution significantly. the relation between surface tension and additive dosage are non - linear relation. each additive has an obvious critical micelle concentration ( cmc )
從混凝土收縮的基本理論? ?毛細管張力理論出發，通過道路混凝土外加劑對水的表面張力的影響研究發現，減水劑對水的表面張力的影響很小，而減縮劑和引氣劑可以大幅度降低溶液的表面張力，溶液的表面張力隨外加劑的摻量呈非線性形式降低，而且都存在臨界膠束濃度。分享友人
