源汇项 meaning in Chinese
source sink term
Examples
- The source and sink is mainly pumping well
源汇项主要是抽水井。 - At the same time , the effects of dragging force from fall of hydrometeors and latent - heat release from phase transfer are tested . from the analyses we conclude that the distributing of the cloud particles relates with temperature closely . huanan heavy rainfall and mei - yu front heavy rainfall have mixed - phase process with vapor phase , liquid phase and ice phase
详细分析了形成降水的云物理过程，探讨了源汇项对水凝物的贡献，并通过敏感性试验，考察了云物理过程对降水热力动力过程的反馈作用，研究结果表明：华南暖区暴雨和长江梅雨锋暴雨的云物理过程具有汽、水、冰三相混合云特征。 - Visual modflow computer code was selected to simulate heads distribution , calculate the zone budgets of the area , evaluate the effect of external stresses on the groundwater head , to determine how much water would be diverted from the river as the result of pumping and to demonstrate how the groundwater model can be used as a comparative technique to formulate a new approach for the quantitative groundwater vulnerability assessment in order to optimize utilization of the resource
在分析河床沉积物渗透性对模型结果的影响时，采用了实际野外水文地质条件而不像前人所采用的假想模型。本论文用visualmodflow建立数值模型模拟预测了地下水水头分布，计算区域的水均衡，分析源汇项对地下水水位的影响。在此基础上进行了全区的地下水脆弱性评价，为地下水资源的合理开发利用提供依据。
