rotational

It is clear that for non-concurrent force systems, similar statements could be made with regard to rotations . 可清楚地看出對于非共點力系考慮轉動時也可以作出相似的結論。

The centrifugal force caused by the earth's rotation decreases from a maximum at the equator to zero at the poles . 地球自轉產生的離心力從赤道的最大值降低到極地的零值。

Positive frequencies are produced by anticlockwise rotation and negative frequencies by clockwise rotation . 正頻率是用逆時針旋轉來產生,而負頻率是用順時針旋轉來產生。

The more general case, when the shaft rotation may be significant, is dealt with in chapter 6 . 在較為一般的情況下,軸的旋轉可能有顯著影響,這種情況將在第六章中討論。

Positive frequencies are produced by anticlockwise rotation and negative frequencies by clockwise rotation . 正頻率是逆時針旋轉產生的,而負頻率是順時針旋轉產生的。

The difference in type of information is probably not present during the first third of a test rotation . 在頭三分之一的試驗周期內,資料的類型可能不存在差別。

Farmers find that they can raise most food by a rotation of plants belonging to the most different orders . 農民已知道,把極不同種類的農作物輪種,收獲最多。

The symmetry of the circle, the square, and the face are associated with rotations or inversions in space . 圓、正方形和人臉的對稱與空間的轉動和交換有關。

The anisotropy associated with the earth's rotation results in a slight deflexion of the ray paths . 與地轉有關的不均勻性會導致波向線產生輕微的偏轉。

The susceptor rested on a pedestal whose shaft is connected to a motor that provides rotation . 感應器安裝在軸承臺上,它的支架與提供旋轉的馬達相接。

In strong fields the magnetization usually changes by rotation of the direction of magnetization . 在強磁場中,磁化往往由于磁化方向轉向而改變。

A person who lives at the equator is in accelerated motion due to the earth's rotation . 一個居住在赤道的人由于地球自轉的緣故是作著加速運動的。

The shaft of fig. 3-33 is simply supported at a and b and is keyed against rotation at a . 圖3-33的軸被簡支在A和B上,并在A處用鍵固定防止轉動。

Also important are the rotation of the slipstream and the change of downwash at the tail . 此外,滑流的旋轉和尾翼處下洗的變化也是重要的因素。

The first boundary error has to be weighted by rotations and second by displacements . 第一個邊界誤差要用轉角來加權,而第二個則用位移來加權。

For geophysical purposes it is customary to use solar rotations of 27. 0 day . 為適應地球物理學的需要,習慣上以270日為太陽自轉周期。
