| 1. | Advances in the inhibition of soil evaporation in farmland 抑制农田土壤蒸发的研究进展 |
| 2. | All we have to do is vaporize the stuff 诀窍就是把土壤蒸发。 |
| 3. | The relations between soil surface resistance and evaporating time , and difference of vapour pressure between evaporating plane and atmosphere were simulated . simulating result of the latter was better than that of the former 同时,还对土壤表面阻力与蒸发时间的关系、与蒸发时间及土壤蒸发面和大气间水汽压差的关系进行了模拟,结果后一种比前一种模拟更符合实际。 |
| 4. | The estimation methods of water requirement , and determination of basal crop coefficient and soil evaporation coefficient under the controlled alternative furrow irrigation in summer maize were studied and verified in the fifth chapter ( 4 )夏玉米田棵间土壤蒸发主要发生在灌后几天表层土壤比较湿润的时期内,其中表层土壤含水率和叶面积指数是影响土面蒸发的两个基本因素。 |
| 5. | ( 7 ) during the process of water consumption , soil water almost lost from the whole profile . the great depth that resulted from evapotranspiration formed soon , but not gradually . infiltrated water was mostly consumed by evapotranspiration during ra ( 7 )在以土壤水分消耗为主的时期,土壤蒸发时水分的整体移动性能较强,最大蒸发蒸腾作用层深度很快形成,并不是一个“由浅而深”的渐进过程。 |
| 6. | The result shows that not only spatial precipitation heterogeneity and spatial land use / cover variability but also spatial soil evaporation heterogeneity influences flood simulation . as remarked above , spatial variability is very crucial to hydrological modeling 计算结果表明不仅降水空间分布、模型参数对水文过程模拟的精度有很大的影响,而且土壤蒸发空间不均匀性对模拟洪水也有一定的影响。 |
| 7. | The effects and mechanisms of different water saving agricultural practices ( mulching , cultivating practice , planting treatments and irrigation treats ) on preventing soil evaporation and the possible measures that should be emphasized in the future are discussed 摘要阐述了节水农业措施(覆盖、耕作方式、种植方式和灌溉制度)对农田土壤蒸发的抑制效果,并分析其抑制土壤蒸发的机制和减少土壤蒸发的可行途径,指出今后该方面的研究重点。 |
| 8. | 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 在构建的数字流域平台基础上,建立分别基于子流域离散和栅格离散的数字水文模型,从而分析研究降水、模型参数和土壤蒸发的空间不均匀性对模拟水文过程的影响。 |
| 9. | This website provides a vast amount of information and resources including : examples of itrc projects , the 2004 itrc short course schedule , on - line reports and papers from1990 to 2003 written by itrc staff , california evapotranspiration data , and related water and soil resource websites as well 该主页提供大量的信息与资源,包括:美国灌溉培训与研究中心项目, 2004年短训课程表,中心员工撰写的自1990年至2003年在线报告与论文,加里福尼亚土壤蒸发蒸腾数据,以及与水土资源相关的网站。 |
| 10. | And this is the first full application of two - layer model in remote sensing . from separated evaporation and transpiration through the model some important field parameters can be derived , such as canopy resistance , co2 flux and crop water use efficiency . a simplified two - layer model was also presented in case of that only radiative temperature is available 在组分温度的帮助下,实现了土壤蒸发和植被蒸腾的准确分离,并且用植被蒸腾速率反算出冠层气孔阻抗、二氧化碳通量、以及作物群体水分利用效率等农田关键参数,是遥感获得此类参数的新思路。 |
