| 1. | The viscous drags is equal to the resultant force .
粘阻力等于合力。 |
| 2. | At equilibrium the resultant of all external forces vanish .
在平衡时，所有外力的合力为零。 |
| 3. | This single force is called the resultant of the original forces .
这样一个单独为力称为原力的合力。 |
| 4. | The summation of forces in this and that directions must be zero .
在这个和那个方向上的合力必定为零。 |
| 5. | In other words, zero resultant force is equivalent to no force at all .
换句话说，合力为零就相当于没有任何力的作用。 |
| 6. | The binding affinity of remaining hemoglobin sites for oxygen is changed by the presence of co binding .
氧在血红蛋白其余位置上的键合力被一氧化碳所改变。 |
| 7. | The resultant force on the loop is evidently zero, since the forces on opposite sides are equal and opposite .
这一回线所受的合力显然为零，因为作用在相对两边上的力是等值而反向的。 |
| 8. | In other words, the vertical component of its linear momentum remains zero, since there is no resultant vertical force .
换句话说，因为没有竖直方向的合力，所以线动量的竖直方向仍为零。 |
