  1. Evapotranspiration is the total evaporation from moist soil and from vegetated surfaces plus transpiration

    濕潤土壤及植物表面的總蒸發量加上蒸騰量稱為蒸散量。
  2. ( 3 ) when evaporation was stopped during the process of soil water redistribution, soil water would move downslope by gravity. when evaporation was in process, due to low initial water content, most infiltrated water from small intensity and amount of rainfall would be consumed by intensive evapotranspiration during rainy season, and lateral downslope unsaturated flow seldom took place. however, soil water would move downslope by gravitational and matric potential gradients after continuous rainfall

    （ 3 ）在防止蒸發條件下，再分佈過程中，土壤水分在重力的作用下有沿坡向下運移的趨勢；在蒸發條件下，由於初始含水量一般較低，雨季量小且分散的降雨極易為強烈的蒸發蒸騰所消耗，側向沿坡向下流難以發生，但在持續的降雨條件下，土壤水分在重力勢和基質勢梯度的作用下易沿坡向下運移。
  3. Evaporation varies from evaporation capability, embedded depth of groundwater is more easy, the effect is more obvious ; evaporation capacity decreases if embedded depth of groundwater become deeply, and close to zero under the some depth ; evaporation capacity of different soil texture is different. at ordinary situation, if embedded depth of groundwater is easy, evaporation capacity of the wide and grit soil is powerful ; if embedded depth of groundwater is deep, evaporation capacity of the slender and viscosity soil is powerful

    潛水蒸發隨大氣蒸發能力的變化而變化，且潛水埋深越淺，受其影響越明顯：潛水蒸發隨潛水埋深增加而減少，在某一埋深以下潛水蒸發接近於零：不同土質其潛水蒸發量不同，一般情況下，在潛水埋深較小時，土質較粗、偏砂性土壤潛水蒸發較大；當潛水埋深較大時，土質較細、偏粘性土壤的潛水蒸發較大。
  4. Based on the observation made on the main crops such as wheat, corn, cotton etc., the observed data from the limited irrigation test for three years are obtained, and then the test data are analyzed with the theory of soil moisture movement and the model of farm crop ' s evaporation is established under the condition of insufficient irrigation

    摘要通過對小麥、玉米、棉花等主要農作物的分階段受旱試驗，獲得了三年的限額灌溉試驗觀測數據；採用非充分灌溉條件下的土壤水分運動理論分析試驗數據，建立了限額灌溉條件下的作物蒸發蒸騰模型。
  5. When water in the soil or in the xylem is put under tension, due to the evaporation of water from a particular site ( which creates a water potential gradient in the direction of the evaporation ), capillarity enables water to overcome the cohesive forces within the water and move against gravity in response to the water potential gradient

    當土壤中或木質部中的水受到張力作用時，由於特定部分水的蒸發（沿著蒸發方向形成水勢梯度） ，毛細現象可以使水克服水分子之間的內聚力並同時沿著水勢梯度逆著重力作用移動。
  6. On the platform of digital basin derived from raster dem data, - a grid - based hydrological model and a subcatchment - based hydrological model were used to study the effects of spatial variability on runoff process on such aspects as precipitation, model parameters and soil evaporation

    在構建的數字流域平臺基礎上，建立分別基於子流域離散和柵格離散的數字水文模型，從而分析研究降水、模型參數和土壤蒸發的空間不均勻性對模擬水文過程的影響。
  7. Milly p c d. a simulation analysis of thermal effects on evaporation from soil [ j ]. water resour. res

    沈榮開，任理，張瑜芳.夏玉米麥秸全覆蓋下土壤水熱動態的田間試驗和數值模擬[ j ] .水利學報， 1997 ， 2 ： 14 - 21
  8. Numerical experiment shows that this heterogeneous disturbance arising from soil water content ' s spatial variability cannot be neglected when regional mean evaporation fluxis estimated

    數值試驗表明，這種因空間變率而引發的非均勻擾動項在估計區域平均通量時具有不可忽視的影響。
  9. Thereby the complicated evaporation process of heterogeneous soil surface is simplified into a flux integral expression which contains two - pail contributions from soil water relatively saturated region and unsaturated region, and it is proved that the calculation of mean evapotranspiration efficiency in grid region can be simplified into weighted average of heterogeneous regions

    從而將非均勻地表區域的蒸發過程的復雜機制分解為地表層土壤水分飽和區與非飽和區影響下的通量貢獻積分式，從理論上證明，網格區平均蒸散率的計算可簡化為不同性質的區域加權平均。
  10. Therefore, metals moving upwards from mineralizations may be absorbed and form weak geochemical anomalies ( weak signals ) in surface loess. the metals can be effectively extracted by neutral salt. loess - covered area in china is primarily distributed at the semiarid region, the secondary carbonates, which were formed after precipitation of ions through evaporation and capillary processes, are widespread in the surface soil

    黃土覆蓋區主要分佈在乾旱半乾旱地區，次生碳酸鹽在地表土壤中普遍存在，蒸發所產生的毛細作用、地氣流的上升作用等所帶入的各種形式金屬元素，在地表土壤（黃土）與碳酸鹽發生共沉澱或被吸持。
