然后,继续增加力-,受到重力的影响,不断给它悬挂重量-,然后它开始弯折,到这里的某一点,我们称之为弹性极限。
And then, when you keep adding force — which we will do by gravity, - we will just hang weights on it — then it starts to bend over, up to a point here which we call the elastic limit.
通过在光学元件边缘施加力矩,产生与重力相反的挠性变形,抵消重力变形的影响。
Torque is applied at the edge of the optical cell to generate flexible deformation offset the gravity deformation.
