But he said the energy of an X-Y bond is going to be equal to the square root.
但他说XY键的键能,会等于XX键与YY键键能乘积的平方根。
That says that if you have independent probabilities, then the probability of two events is equal to the product of their probabilities.
意思是,几个相互独立的事件,其中两个事件同时发生的概率,等于他们分别发生的概率的乘积
And if you're below this temperature here, this quantity, p times v it would be negative.
压强与体积的乘积将变成负数,这可能吗?
We don't know what the force is, because we are hoping to say force is going to be m times a.
我们不知道力有多大,因为我们希望力是 m 和 a 的乘积
So you take the square root of the product.
你应该用乘积的平方根。
If you had one negative number in it, then the product would be a negative number and, if you took a root of that, then you might get an imaginary number.
如果这当中有一个负数,乘积就会变成负的,如果你对一个负数开根号,你就会得到一个虚数
So the product would be negative.
这样乘积就是负数
n It takes discrete values, multiples of some integer n, and the multiplication factor is the ratio of the Planck constant divided by 2 pi where n takes one, two, three and so on.
这些离散的值乘以整数,乘积因子,是普朗克常数除以2π,其中n可以取1,2,3,等等。
The property is the limit as p goes to zero of pressure times molar volume.
与摩尔体积的乘积,在气体压强p趋于0时的极限。
Then we may, from this equation, say a certain force is acting in a given situation by multiplying the m times the a.
然后根据这个方程,我们就能说,得到给定条件下的作用力,它等于 m 和 a 的乘积
That m times a is the force the spring is exerting.
与 a 的乘积就等于弹簧产生的力
It is defined as rho= That's the correlation coefficient.
定义为,rho等于xy的协方差比xy各自的标准差的乘积,这就是相关系数
For example, we know that if a body is near the surface of the Earth, the force of gravity of that object seems to be m times g, where g is 9.8.
例如,我们知道,如果在地球表面有一个物体,该物体受到的重力大小为 m 与 g 的乘积,g 等于 9.8
