At current growth rates, the W.H.O.expects the number to reach twenty million by two thousand fifteen.

Unfortunately, this is also call the Rydberg constant, so it's a little bit confusing. But really it means h the Rydberg constant divided by h, and that's equal to 3 .

不幸的是，它也叫Rydberg常数，所以这可能会有点混淆,但它表示Rydberg常数除以。

H And, by the way, if you do this for the hydrogen, H it ought to come out the same.

顺便说一句，如果是，或者如果是。

printf That's not actually where someone implemented print F and related functions, rather, in dot H files, by convention, are prototypes.

那实际不是有某人在哪里执行,相关函数，而是在，h文件中，按照惯例，它们是函数原型。

So I show that here, so in green, you have what's called a carboxcylic acid group, a c o o h, which gets converted by s o c l 2 to a c double bond o c l or an acid chloride.

我在这里用绿色表示，我们所说的羧酸族化合物，碳，氧，氧，氢，它被亚硫酰氯转化为,一个碳氧双键与碳氯单键组成的酰氯。

OK, delta H is delta of u plus pV. By definition that's how we define enthalpy up here.

好，ΔH=Δ,根据定义，这就是我们。

So, since the speed of light equals lambda nu, we can say that momentum is equal to h divided by lambda.

所以，既然光速等于λ乘以υ,我们可以得到动量等于h除以λ

stdio h This file here is called standard I/O or stdio.h and this is just another text file someone else wrote many years ago and by using that line of code there, I'm telling the computer, give me acces to this code that this other person wrote that's in that file.

在这里的头文件称为标准输入输出文件或,这是由某位前人编写的文本文件,我们只需要刚才所述的一行代码，就能告诉电脑，让我连接到,这个前人在那个文件中写的代码。

So we can figure out the energy of each photon emitted by our UV lamp by saying e is equal to h c over wavelength.

所以我们可以计算出,每个从紫外光源射出的光子,也就是e等于h乘以c除以波长。

So, we can get from these energy differences to frequency h by frequency is equal to r sub h over Planck's constant 1 times 1 over n final squared minus 1 over n initial squared.

所以我们通过不同能量,得到不同频率，频率等于R下标,除以普朗克常数乘以1除以n末的平方减去。
