| 1. | The critical state of flow is defined as the condition for which the froude number is equal to unity . 将弗氏标数等于1的情况规定为流动的临界状态。 |
| 2. | The argument hangs around what is known as a froude number 问题就在于那个著名的“弗鲁德值” 。 |
| 3. | Volume froude number 排水容积傅汝德数 |
| 4. | If the froude number exceeds 0 . 5 , then it is more efficient to run than to walk 如果弗劳德数超过0 . 5 ,跑动就比步行更有效。 |
| 5. | If the froude number exceeds 0 . 5 , then it is more efficient to run than to walk 如果弗鲁德值超过0 . 5 ,那跑步比走路更省力。 |
| 6. | If the froude number exceeds 0 . 5 , then it is more efficient to run than to walk 如果佛氏数大于0 . 5 ,那么奔跑比行走更有效率。 |
| 7. | In this essay a kind of auxiliary energy dissipator arplying to underflow energy dissipation of low froude number is developed . it mainly applies to the small - sized projects , especially to the canal system structures 本文研究了一种适用于低佛氏数底流消能的辅助消能工? ?拱形网板(简称拱网) ,它特别适合于小型工程尤其是渠系建筑物。 |
| 8. | The results of soil trough experiment indicated that , the flow velocity and froude number would add when the rainfall splash intensity rose ; the flow depth and resistance coefficient would decrease when the rainfall splash intensity increased 土槽试验结果表明:土壤坡面薄层水流流速和弗汝德数随雨滴打击强度的增加而增加,水深、阻力系数随雨滴打击强度的增加而降低。 |
| 9. | The results of flume experiment indicated that , the flow velocity and froude number of the overland flow would fall with the rainfall splash intensity rose ; the flow depth and resistance coefficient would enhance with the rainfall splash intensity increased 水槽试验结果表明:水槽槽面薄层水流流速及弗汝德数随雨滴打击强度的增加而降低,水深、阻力系数随雨滴打击强度的增加而增加。 |
| 10. | The quantitative relational expression is obtained about the coefficient of additional pressure loss and the froude number by experiment , and the relation is made clear between the average speed of waste plastics particles and the pressure loss of per unit length 由实验得出废塑料输送管内气力输送附加压力损失系数与弗劳德准数的定量关系式,废塑料颗粒平均速度与单位管长压力损失的关系。 |
