effective stream meaning in English

有效射流

Secondly , the total resistance is studied directly . the relationship between total stream power and effective stream power is proposed by analogizing the method of engelund
二是直接研究河床总阻力，类比engelund的方法，建立了总水流功率与沙粒水流功率的关系。
The measured data show that the bedload sediment transport rate is related more closely to the effective stream power within the bed - surface layer than to the river stream power
实测资料表明，推移质输沙率与床面层内有效水流功率有良好的相关性，且高于推移质输沙率与水流功率的相关性。
Based on the relationship between energy and flow within the bed - surface layer , a relationship between the bedload sediment transport rate and effective stream power within the bed - surface layer is derived
摘要基于床面层内的水流能量关系，推导了推移质输沙率与床面层内有效水流功率的关系式。
