This is Comus, line 588 -- the Elder Brother. The brother says: Virtue may be assail'd but never hurt, Surpris'd by unjust force but not enthrall'd, Yea even that which mischief meant most harm Shall in the happy trial prove most glory.

这是《科玛斯》，第588行--哥哥这个角色，他说：,诗歌大意：，贞操或许遭袭，却不会受损，或许为不义之力突袭，却不会乱了阵脚，是的，对于贞操最重的伤害也不过是玩笑,考验只是证明它无上的荣光。

The force may taper off, the force may not be given by a straight line, but for modest deformations, every spring will have a linear regime in which the force is linearly proportional to the stretching.

它产生的力可能会渐渐消失,力的曲线可能不是一条直线,而有轻微的弯曲,每个弹簧都有一个线性区间,在这一区间内,力和伸长量是线性关系

What makes the law surprising is that if I only gave you half the law, namely every body will remain at rest if it's not acted upon by a force, you will say, "That's fine. I accept that, because here's something, you leave it there, it doesn't move.

这条定律妙就妙在,如果只看定律的前半段,即,如果物体不受外力作用,将保持静止状态,你肯定会觉得,"这没什么,我能理解,因为你把一个物体放在那里,自己肯定不会动

When you say the rope is under tension being pulled from both sides by a certain force, the tension is not 0 just because this T and that T cancel.

当绳子被绷紧,即两端被拉伸时,拉力并不为 0,因为这个 T 和那个 T 相互抵消了
