This normal weight animal like this has its whole equilibrium thrown off, its homeostasis thrown off when its dietary conditions change.
在饮食条件发生变化时,这些正常体重动物的生理平衡被打破,于是摈弃了原来的平衡饮食
And so what I get is the energy of the system at the equilibrium separation is given by minus z plus.
这就是通过减去z+得到得平衡分离时,我得到的能量体系。
You adjust the lengths and when it balances, you can sort of tell what this mass is, right?
调整它与支点的距离,然后当它平衡时,你就能得到质量是多少,对吧
It doesn't tell you, this is the equilibrium concentration that you'll end up with.
他无法告诉你,最终平衡时的浓度是多少。
So, in other words, what happens if we put a bunch of elements, compounds into a reactor but they are not in the balanced amounts?
换句话说,如果我们将一堆的元素,放到一个反应器里面的话,而他们不是平衡时的比例会发生什么呢?
I tie a spring to my back and I anchor it to the wall and see how much the spring stretches before the two forces balance.
我把弹簧一端系在背后,另一端固定在墙上,观察两个力平衡时弹簧的伸长量
That's how by either balancing the unknown force with a known force or by simply measuring the acceleration as I fall towards this podium and multiplying by mass, you can find the force that exerts on me.
我们既可以让未知力与已知力平衡,也可以只测量我冲向讲台时加速度的大小,再与我的质量相乘,都能求出作用在我身上的力的大小
