couple of forces
解釋
力偶-
This method makes it possible for investigating the unsteady nonlinear potential flow in a complicated environment with higher efficiency. the aerodynamic forces of a wing in couple motion of heave and pitch with ground effect are analyzed in detail based on the numerical result. it is shown that a thrust force exists when the wing is in heave motion
深入系統地分析了存在表面效應時機翼運動規律和氣動力之間的關系，研究結果表明，機翼升沉運動產生的推力與升沉速度幅值的平方成比例，推力和推進效率和振蕩頻率成反比；機翼的俯仰運動可以調節推力和推進效率，但是單純的俯仰運動不會產生推力。 -
A torque of this kind, arising from a pair of equal and opposite forces, is sometimes called a couple.
由一對相等而相反的力產生的這類轉矩，有時叫做力偶。 -
Multicast technology promises to enhance the capabilities of wide - area networks for supporting these applications. multicast transport mechanisms have been a topic of intense research and development efforts over the past couple of years. both the internet engineering and internet research task forces ( ietf and irtf ) have been heavily involved in coordinating multicast transport protocol research, development and standardization
組播是一種高效率的點對多通信方式，在過去幾年中組播傳輸機制己經成為一個活躍的研究領域， irtf和ietf （因特網研究和工程任務小組）在組播傳輸協議研究、開發、標準化等方面作了大量的工作。
