总蒸发

一个改进的计算麦田总蒸发量的能量平衡&空气动力学阻抗模式

An improved energy BALANCE-AERODYNAMIC resistance model used estimation of evapotranspiration on the wheat field

小麦地蒸发强度大，蒸发高峰出现早且具有最大的年总蒸发量；

In wheat fields , an high evapotranspiration intensity with a peak which happened earlier and a maximum annual rate of evapotranspiration were found .

文中还给出了燃料总蒸发速率和单位长度上的蒸发速率随该发动机燃烧室轴向距离变化的曲线。

Curves of total vaporization rate of fuel and vaporization rate per unit length as functions of the axial distance of combustor for given rocket engine are also presented .

本区域内广泛采用覆膜作为农业增产措施，覆膜管理方式有效抑制了蒸发，使总蒸发量大幅度下降，保证了耕层土壤有较高的含水量，增加了耕层的土壤温度，从而到达增产的效果。

Mulching with plastic is a widely used measurement of increasing agricultural production in this region . Plastic mulching measurement can effectively inhibit evaporation to significantly decline the total evaporation so as to ensure that the topsoil has a higher water content .

结果表明，夏玉米总的蒸发蒸腾量在年际间变化较大，其中叶面蒸腾总量变化较大，在158.44-233.99mm；

The results showed that the change of total evapotranspiration was large among years , among which the change of total transpiration is larger , the range of transpiration changes from 158.44 mm to 233.99 mm ;
