"I can understand that people who actually lived at that time, in the communist era, who were hurt by this system it might upset them to see young people who might have basically no knowledge about this system and didn't live in that, wearing the symbols they don't understand.

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。
It means that the properties of the system, the properties that describe the system, don't change in time or in space.
它的意思是指,用以描述系统的性质,不随时间或空间改变。
The U.S. was practically the last country to copy this system because, in the 1930s, because it didn't sound American.

So, they don't start killing all the cells in your respiratory system; they only kill the cells that are harboring the virus.

If you don't account for them all in your design, the system may not work.
若设计时不能全面考虑,该体系就行不通。
Once you have registered, if some other slots become available that weren't previously available, I gather you'll be sent some sort of email by the system, in case some other time would be better for you.

They have refuse to pay the cost that maintain the health care system, and so in countries like Britain and Canada, t find the same availability of health care like that in the United States.
政府拒绝为民众买单,维持医疗福利,所以在英国和加拿大这样的国家,你找不到,you,don’,同样方便的医疗,可以与美国媲美的。
In the nervous system it doesn't work that way.
在神经系统中并不是这样
Don't worry about how they work in the immune system, but what if you could manufacture antibodies then you could make a chemical, an antibody, that is capable of binding to a specific other chemical and you could use that for things.
别管它们在免疫系统内是怎么工作的,只要考虑能不能制造抗体,那么假设你能制造这种化学物质 抗体,抗体又能够同其他特别的化学物质结合,你就可以让抗体为我所用
So we'd really like to be able to find some sort of equation of state, or some sort of rather function of state that's going to relate the heat going in or out of the system with that function of state, because this isn't going to do it.
所以我们真的想要去,找到一些态方程或者态函数,通过这个态函数可以表示热量,在系统与外界的交换,因为这个不能表示它。
That shouldn't be too surprising given what we talked about last week, that your immune system, the adaptive immune system in particular, responds to individual antigens differently.
你们不必惊讶,上周我们讲过免疫系统,特别是适应性免疫系统,对不同抗原的应答是具有特异性的
If banks get in trouble and they can't pay out -if one bank gets in trouble and can't pay out on its deposits, then that can bring the whole system down because it can cause a panic among investors -among depositors and banks -and create a run on a bank.
如果银行出现问题而且他们无法支付...,如果一家银行出现问题,并且无法支付提取的存款,那么这就会使得整个系统崩溃,因为这会在投资者中引起恐慌...,在存款人和银行中引起恐慌,并且造成银行挤兑
The immune system, some cells of the immune system, in particular this class of T-cells called CD8 cells have receptors which recognize MHC1.
免疫系统,其中一些免疫细胞,特别是T细胞中的,CD8细胞含有可识别MHC1的受体
Here's where the intelligence of the immune system comes in, is that these cytotoxic T-cells that are generated only kill cells that have this signal on it.
免疫系统的聪明之处就在此,这些细胞毒T细胞,只能杀死具有特殊标记信号的细胞
So, that's antigen presentation to this population of cells called cytotoxic T-cells, Tc, a subset of the class of T-cells in the immune system.
这些细胞被呈递给另一种细胞,这些细胞被称为细胞毒性T细胞,是免疫系统中T淋巴细胞的亚群中的一种
If you take an organ from one person and put it in another, if their MHC molecules don't match then the immune system recognizes the immune system of the host recognizes 'this is not the right MHC for me' and the immune tries to destroy those cells.
如果将器官从一个人移植到另一个人,免疫系统识别出MHC分子并不匹配,宿主的免疫系统就会说,这不是我的MHC,免疫系统就会试着摧毁移植器官的细胞
