Therefore , the ultimate target of basin hydrological model is to develop models based on dual water evolvement mode . so this is bmbc 因此，对流域水文过程研究的最终目的，就是建立基于“流域二元水循环模式”的流域水文模型。
" but for all of those theories , one needs to understand the water cycle : how much water there was , where it went to , and where it ' s at now 但是，在所有的理论中，人们应该弄清的是水循环：曾经有过多少水，流向了哪里，现在在哪里。
Base flow separation method and isotope technique were adopted to study the cyclic relationship between river water and groundwater 通过基流分割计算和同位素技术的应用，研究了区内地下水和地表水之间的水循环规律及地下水对黄河的贡献。
Based on the traits and existent problem of water cycle in western china , the key scientific issues of water cycle in western china has been addressed in this paper 从中国西部流域水循环的特点及存在的问题出发，探讨了中国西部流域水循环研究基础科学问题。
To the former , the great influence brought to the natural water cycle has always been ignored . consequently , enormous damage has been made to the environmental value 在第一类活动的实践中，对自然水循环造成的重大影响常常被忽视，从而造成对环境价值的巨大破坏。
As a matter of fact , contradictions like this exist not only in places with pond or river , but also in places without water - pond , owing to the ubiquity of water cycle 并非只是有水体存在的地方才存在这样的矛盾，事实上在没有水体的地方同样存在，因为水循环是无处不在的。
Products and systems for the protection and repair of concrete structures - test methods - volume and weight changes of injection products after air drying and water storage cycles 混凝土结构的保护和维修用产品和系统.试验方法.空气干燥与储水循环后注入产品的体积和重量的变化
Rapidly increasing oxygen in water , driving water circulation in pond , and efficiently handling hypoxia in fish , prawn and eel , it is a necessary tool of increasing oxygen for aquiculture 1迅速增加水中氧气，推动池中水循环，有效快速解决鱼虾鳗等浮头现象，是水产养殖的必要增氧工具。
Soil water infiltration is aimportant link in nature water cycle , study on soil water infiltration may make sure reasonably farmland irrigation technical parameter to offer science reference 土壤水分入渗是自然界水循环中的一个重要环节，土壤水分入渗问题的研究，可为合理确定农田灌溉技术参数提供科学依据。
The technology we first research heat for twice is successful , let the connection of the high temperature high effect and hot water fast circulation perfect , pushing the solar energy into a new stage 我们首次研发的“二次换热”已取得成功，使得高温度高热效高热水循环更加完美，将太阳能热水器推向了一个新台阶，新舞台。
