So what they do is, they're describing how these thermodynamic properties change, in terms of only state functions and state variables.
他们的作用是描述,随着状态函数和状态变量的变化,系统的热力性质如何变化。
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。
And I want to remind you, that block of code is a set of instructions, the same set of instructions that are going to be done each time through the loop.
我想提醒大家,这块代码是一个指令集,一个每次循环都会被执行的相同指令集,会变化的仅仅是变量的值。
A futures market has a prediction going out years into the future of what every financial variable will be doing, so you can see the future in a sense through the futures prices.
一个期货交易市场,预测了未来几年,每个金融变量的变化,因此,在某种意义上,你们可以通过期货价格分析未来市场
Then the second derivative gives the change in entropy with respect to the variable that we're differentiating, with respect to which is either pressure or volume.
二阶导数给出熵,随着变量变化的情况,这些变量包括压强或者体积。
And remind you that inside of here, I'd better be changing the variable. All right, if that variable that's counting is not changing I'm going to be stuck in an infinite loop, so I ought to that, right, expect somewhere in there, a change of that variable. All right?
我最好改变了计数器的变量值,好,如果计数的变量没有变化的话,我就会被卡在一个无限循环里面,因此我应该【不可闻的声音】,对,在这里的某个地方,改变下计数器的变量,对不对?我要做的最后一件事情就是?
And the useful outcome of all that is that p we get to see how entropy changes with one of those variables in terms of only V, T, and p, which come out of some equation of state.
这样做的重要结果是,我们得到了熵随着V,T或者,其中一个变量变化的情况,这些可以从状态方程得到。
