"One of the absolutely key, most important variables as to whether or not a forest survives and continues is whether local people monitor each other and its use.
VOA: special.2009.10.16
Now, this is still a little bit cumbersome, in part because of the variables involved, S including S.
但是这个方法还是有一些笨拙,部分是因为所涉及的变量,包括。
I don't know what the names of the variables are, I don't care, I can basically suppress away that detail.
在solve函数中使用了些什么值,我不知道里面的变量的名称,我可以简单的跳过这些细节。
ArgV You can think of this variable Arg V as literally an array a sequence of chunks of memory that literally are back to back to back in memory, and when you say bracket zero, by convention, you are referring to the variables stored here.
你可以想象这个变量,按顺序排列的一块块内存,依次地在内存中紧邻着的,当你指明,按照惯例,涉及,存储的变量在这里。
That is, in real life, the variables that you'd normally control aren't some combination of entropy and these variables, but really their temperature, volume and pressure, any couple of those, might be what you'd really have under experimental control.
在生活中,我们所能控制的,不是熵和其他变量的组合,而是温度,体积,压强,以及其中的两两组合,这些才是试验中所能控制的。
That's not just a set of functions--variables, as one might say in the lab.It's produced by genius.
它不仅仅只是一套机器,像人们在实验室所见的一样多变,它是由天才创作的。
The Taylor rule specifies specific variables and everybody at the markets would understand the rule, ? and that's correct, right?
像泰勒规则就明确了具体的变量,市场中每一个参与者也都能够理解,这个没错吧?
So similarly, as we now move up only one more atom in the table, 3 so to an atomic number of three or lithium, now we're going from six variables all the way to nine variables.
类似地就像我们现在,移动到周期表中仅仅多一个电子的情况,移动到一个原子数为,或者锂元素,现在我们从6个变量到了9个变量。
The big three are three variables that the effects are so powerful that they almost don't need to be discussed in much detail.
是指三大因素,力量很强悍,我们几乎不用说得太细。
I think that book will give you all the basic principles you need in calculus of one variable, more variables, elementary complex numbers, maybe solving some problems with vectors and so on, which you're going to get into.
我想那本书会给你所需的所有基本知识,包括一元和多元微积分,简单的复数运算,可以解决一些与矢量有关的问题,而这正是你们将要学的
You have discrete random variables, like the one I just defined, or there are also--which take on only a finite number of values-- and we have continuous random variables that can take on any number of values along a continuum.
就像刚定义的,是一个离散型随机变量,随机变量还可以有无限种取值,也就是连续型随机变量,随机变量可以取某一区间的一切值
So, these on-changing properties that describe the state of the equilibrium state of the system are called state variables.
这些描述,系统平衡态的,变化的属性,就叫做状态变量。
OK. So if we have variables, one of the questions we can ask is, what's the type of the variable.
好,如果我们有了一个变量,我们要问的问题之一就是,这个变量的类型是什么?
I've decided that I need to be able, in my program, to swap the value of two variables. All right.
我觉定在我的程序中,我可以,交换两个变量值,好的。
You don't have to mention any of the local variables, because at this point in the story, they're just not relevant.
你不需要提及任何一个局部变量,因为在这个地方,它们是不相关的。
So the state variables describe the equilibrium's state and they don't care about how this state got to where it is.
状态变量,描述平衡态,它们并不关心,系统是如何演化成这样的。
It turns out that slightly before the stack, slightly before this conceptual chunk of memory, there's other things called environment variables that we may see over time but elsewhere in memory are other things.
结果是稍微在堆之前,稍微在这个内存块概念之前,另外还一个东西叫做环境变量,我们之后可能看到,内存中的其他地方,是其他的东西。
So when I do the analysis, I want to think about what am I doing here, am I capturing all the pieces of it? Here, the two variables that matter are what's the length of the list, and how many times I'm going to search it?
这里,要关注的,两个变量是列表,的长度以及我要搜索的次数,这种情况下,这个算法赢了?
So it's initialized outside the loop when it should be initialized inside the loop. Or conversely, inside the loop when it should be outside the loop. So look carefully at when variables are being initialized.
却忘记了,意思就是它本来应该,是在循环外初始化,但是却是在循环初始化的,所以在初始化变量的时候注意这一点。
Now in a stoplight, it only has three, one is tempted to say, variables plainly differing from each other: red, yellow and green we have two ways of thinking about the red light.
交通灯,三种灯,红黄绿,它们的颜色和彼此不能,我们有两种方式认识红灯的意思。
Well, because the memory we've been using for local variables, and for functions, storage space is what computer scientists generally call the stack.
好的,因为我们看到的内存是用于局部变量的,用于函数的,存储空间就是计算机科学家,通常说的堆。
We're going to find other properties that do care about the history of the system like work, that you put in the system, or heat that you put in the system, or some other variables But you can't use those to define the equilibrium state.
我们还会发现其他一些,与系统的历史有关的性质,比如你对系统做的功,或者你向系统传递的热量,或其他的变量,但你不能用它们,来定义平衡态。
Conceptually, it's put at the top of my chunk of RAM, -- below it, goes initialized and uninitialized data -- - this is a fancy way of saying global variables come next -- and below that, comes what's called the heap.
概念上,它放置在内存块的顶端,在下面,已初始化的和未初始化的数据-,这是一种指明紧随其后的全局变量的设想方式-,在后来,引入了一个叫做堆的东西。
At the top of your file, you can also put variables there.
在文件的顶端,你们也可以加入一些变量。
But we said earlier that, you know, we're going to get - to the point where we want to have a lot of pieces of -- a lot of variables in memory, maybe 140,000 dictionary words for some future peace set, but we don't want to enumerate line by line by line 140,000 variables.
但是我们之前说过,你们知道的,我们将获得,有很多块--很多变量的内存的指针-,可能有140,000个单词的集合,但是我们不想一行行地列举,140,000行变量。
All the local variables can be dealt with later.
所有的局部变量将在之后处理。
So, you need to know the variables.
你需要知道采用哪些变量。
On the other hand, temperature, volume and pressure are variables that are much easier in the lab to keep constant.
另一方面,温度,体积和压强,在实验室中比较容易保持恒定。
It tells you what kind of molecule it is andgives you twovariables that are state variables You could have the volume and the temperature.
告诉你它是哪种分子,还给你了两个状态变量,它们可以是体积或温度。
If you have the number of moles and two intensive variables, then you know everything there is to know about the system.
如果你有摩尔数,和两个强度量,你就能知道关于这个系统的一切,关于系统的平衡态的一切。
