1) approach velocity
行近流速
1.
3 m in width,by multiple groups stability experiments of sand ribbed soft mattress at dike head under conditions of different dike lengths,approach velocities,water depths,and block thicknesses,it shows that the stability is related to the block thickness on the sand ribbed soft mattress,the ballast thickness is correlative with the dike length,approach velocity and water depth.
3m的水槽,对砂肋软体排在不同压载厚度条件下进行不同行近流速、不同坝长、不同水深的多组次室内试验研究,得到砂肋软体排的稳定性主要与压载的块石层厚度有关,铺设在丁坝坝头的砂肋软体排临界块石压载稳定厚度与行近流速、丁坝长度以及水深等因子有关,采用相关因子多元回归分析得到丁坝坝头砂肋软体排临界稳定的压载厚度经验公式,可指导现场施工实践。
2) velocity of bottom of water
近底流速
1.
Professor Wen Heng and his students found that velocity of bottom of water is too much,and found that roughened apron by waste tires can adjust velocity and low velocity of bottom of water .
文恒教授等研究发现,利用废旧轮胎对海漫进行柔性加糙,可充分调整海漫下游流速分布,降低近底流速,对于解决闸下冲刷破坏,效果非常显著[1,4]。

5) rate of epidemies
流行速度
1.
The movement of disease index of infected leaf of soybean in filed expressive “s” form, and the rate of epidemies of disease index can forecasting by k.
灰斑病叶的病情田间动态分布呈“S”型,病情的流行速度可用K。
6) epidemical rate
