[英]['pə:kə,leit] [美]['pɝkə,let]
渗流;渗透
5) permeating airflow
渗透气流

针对地下通风中的渗流问题 ,选取一个有代表性的渗流区域作为原始模型 ,通过相似分析 ,确定模型主要参数 ,进而建立了用于研究渗流运动规律的实验模型 ,该模型对把握渗透气流的运行轨迹 ,验证渗流速度场通用数学模型的正确性 ,确立流态指数与渗透速度之间的关系等方面 ,起到了重要作用。
6) seepage velocity
渗透流速
1.
Model research of heat source method by using water temperature distribution in borehole to determine seepage velocity of dyke;
利用孔中温度场分布确定堤坝渗透流速的热源法模型研究
2.
There exist shortcomings or restricted conditions in preceding formulae of obtaining the seepage velocity.
地下水渗透流速是一个很重要的水文地质参数,示踪技术可较为准确地估算地下水渗透流速。
3.
Owing to are some questions about the traditional dilution formula and the generalized dilution formula deduced by predecessors,a new dilution formula was derived to calculate seepage velocity with tracer method,based on the condition that there existed vertical flow in the borehole and a reasonable physical model was adopted,considering the seepage velocity as a function of tracer dilution time.
基于传统稀释公式和前人推导的广义稀释公式存在的种种问题,在钻孔中存在垂向流的情况下,在合理的物理模型的基础上,考虑了渗透流速是示踪剂稀释时间的函数,重新推导了示踪方法测流速的稀释公式。
补充资料：土壤细流
1.语出《史记．李斯列传》:"是以太山不让土壤，故能成其大;河海不择细流，故能就其深。"后因以"土壤细流"比喻微不足道的事物。
