| 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
