But through technique alone to the extensity even existence cannot be found alone There isn't any or many or much meaning maybe limited cases I don't care.
当时仅仅通过技术,连存在都难以实现,如果这样,有技术也没有什么意义了,或许我举的例子不多。
I don't have any very good answers for that and yet it is one part of the traditional explanation is this, and it's a very important one and much debated, that at a critical time in the battle one technique would be one side would give one great big shove.

There's one on DNA fingerprinting, for example, that gives you a little bit more detail about that specific technique; another one on production of therapeutic proteins.
例如,这里有一段,是关于DNA指纹图谱法,提供了这项具体技术一些更详尽的细节,另一段是关于治疗性蛋白质的生产的
Here's the problem with that technique, and by the way, a number of programming languages use this, including Lisp.
这会指向元素的值,然后对内存进行切分,关于这种技术有个问题,顺路说下。
And, in fact there's a technique of analysis used today that's called Rutherford back scattering where people actually saw that this is a means of identifying the substance, the sample.
事实上这是现在用的一种分析技术,称作卢瑟福背散射,就是人们实际上看到的那样,这是鉴别物质样品的一种方法。
So I said that this technique was used to experimentally determine what the different binding energies or the different ionization energies are for the different states in a multielectron atom.
我说过,这项技术被用来,在实验上确定多电子原子的,各个不同态相应的束缚能,或者电离能。
But the point is still the same that technique is in itself doesn't provide meaning.
但我的观点仍是,技术本身并没有什么意义。
The technique I want to talk about is one called Polymerase Chain Reaction.
我想讲的技术是聚合酶链式反应
And this is what lies at the heart of this very general technique called dynamic programming.
这也就是动态编程,这种通用技术的核心。
Lisp The problem with that technique, while it's very general, is how long does it take me to find the i'th element of the list?
很多编程语言包括,都是用了这种技术,这个问题就是,当数组很大的时候?
I'm going to show you one last technique.
我要给你展示最后一项技术。
It's not merely a function of technique.

but though there were also chapters that analyze films to be count as being a form of films studies, too but the first chapter is concerned about the whole question about form and content technique and meaning.
虽然也有章节,是分析电影的,所以这本书也算讨论了电影,但是第一章讲的是,关于内容和形式的问题,关于技术和意义的问题。
We did not yet have good methods for screening blood to look for HIV, we didn't have the ELISA technique that I--we talked about in section a few weeks ago and so there was a great concern that there might be other diseases that you'd be passing on from-- unknowingly from this subset of patients that you're isolating the vaccine from.
那时我们还没有一种好的方式,来从血液中筛查出HIV,也还没有ELISA技术,该技术我们在几周前的一个章节中谈到过,因此,那时仍存有,很大的担心,那就是你有可能,在不知情的情况下,被那些病人,感染上其它疾病,因为疫苗就是从他们身上提取出来的
