"because the virus can spread rapidly, but what we're seeing so far is a pretty stable position as far as the virus is concerned, it's producing relatively mild illness in most people, but in a small proportion it's causing serious problems and we have in place the plans in our health care system to deal with those problems,".

Hydrogen gas it's in its most stable state, right at room temperature and pressure.
和常压下氢气是氢元素,最稳定的状态,这个小“0“
It then made Massachusetts the most stable state or essentially the most stable state in the country and it was widely-admired.
那时,它使马萨诸塞州成为了美国最稳定的州,或者说本质上最稳定的州,并广受好评与赞赏。
Now in this particular reaction, I've got hydrogen gas, iron solid. Those already are elements in their most stable forms at room temperature and pressure.
特定的反应中,我有氢气,固态铁,这些都已经是,处于室温和常压下,最稳定的元素单质。
But I want you to tell me in terms of thinking about formal charge, which Lewis structure would you predict to be the most stable?
但我想让大家告诉我,从形式电荷的角度考虑,你会预测哪一个路易斯结构是最稳定的?
We take in a lot of food and water everyday, every year, and yet most of us our weight stays remarkably stable over that period of time for adults despite how much we eat and how much we drink.
日复一日年复一年,我们都摄入大量的食物和水,但我们绝大部分人的体重,在成年期都保持得很稳定,不管我们怎样大吃大喝
Delta H of formation means the enthalpy of this compound minus the enthalpy of its constituent elements in their most stable state at room temperature and pressure.
生成焓就是这种组分,的焓减去它的所有组成元素,在室温和常压下处于,其最稳定的状态时的焓。
Iron as an element is a solid. That's it's most stable state at room temperature and pressure, right, and so on. And then we can figure out heats of formation.
铁单质是固态,这是他在室温和常压下,最稳定的状态,然后我们,可以算出生成热,现在这个。
We knew from Friday, when we talked about energy, that ground state was that n equals 1 value, that was the lowest energy, that was the most stable place for the electron.
我们上周五知道了,在讨论能量的时候,基态指,n等于1的态,它能量最低,是,最稳定的态。
So what we see is that structure a is the most stable because we have the least separation of charge in the case of structure a.
因此我们看到结构,A,应该是最稳定的,因为这种情况下,分开的电荷最少。
