flow factor meaning in Chinese

流动性系数
流量系数
流量因数

The surface material is liable to erosion wear with high - velocity sediment - laden flow , hi this paper , sand wear mechanisms are discussed and some effects of significant flow factors on material wear are analyzed ; the possibility of preventing erosion wear with aeration is proposed ; based on test data , the formula for calculating the concrete material wall surface wear rate is derived . it is indicated that the wear rate is related to the air concentration , the strength of material , the flow velocity and the sediment content . it is shown that wear rate can be reduced with the help of flow aeration
分析了空蚀与磨蚀的不同物理特征；探讨了沙粒磨蚀机理，提出了影响磨蚀vi河海大学博士学位论文一的因素；研究了掺气抗磨的可能性：建立了混凝土材料壁面磨蚀率的计算公式；说明含沙水流对固壁材料的磨蚀率随掺气浓度、材料强度的增大而减小，随水流流速、含沙量的提高而增大；利用掺气可有效地降低过流表面的泥沙磨蚀率。
