Their condition only proves what squalidness may consist with civilization.

他们的处境只是说明其贫困跟文明的发展水平相反相成。

And there are also mirrorless cameras, which are a cross between compact cameras and DSLRs.

并且还有无反相机，它们是小型相机和反相机的结合。

Ah, well then I'd recommend a nice entry-level digital SLR.

啊，好的，那我推荐您这款不错的入门级反相机。

Called the Lytro Illum, it looks like a serious SLR camera and has a 1,600 price tag.

这款名为Lytro Illum的相机造型和高端专业反相机类似，定价是达到1600美元。

So camera makers are now moving to the more high-end market, the DSLRs and mirrorless cameras.

所以相机制造商们现在正转向高端的市场，反相机和无反相机。

The Q is an output, and the Q bar is the inverted output.

Q 是输出，Q 条是反相输出。

So right now, all you need is the camera and a tripod and, you know, a lens if you have a DSLR.

所以现在，你只台相机、个三脚架，如果你使用的是反相机，还个镜头。

An inverter on its own flips the input from a 1 to an output of a 0 and vice versa.

个反相器本身会将输入的1转换为输出的0，反之亦然。

Moving down to see inside the sense amplifier, we find a cross-coupled inverter.

向下查看感测放大器内部，我们发现了个交叉耦合反相器。

They are small like a compact camera but you can also use the same lenses on them that you can use on DSLRs.

它们像小型相机样小巧，但是你还可以在它们上面使用跟在反相机上使用的样的镜头。

Due to the odd number of inverters, the output rapidly oscillates between a 1 and a 0.

由于反相器的量是奇，输出会在1和0之间快速振荡。

So it's nice to have, if you need the inverted output signal, you can just spare an inverter after that.

所以很高兴，如果你反相输出信号，你可以在那之后备用个反相器。

A curious friendship theirs must have been: a pointed illustration, indeed, of the old adage that " extremes meet" .

他们的友谊必定十分奇特，的确是对“相反相成”这句谚语的鲜明写照。

By contrast, if the waves are exactly out of phase, one rising as the other falls, the interference will be destructive.

相反， 如果波完全反相，个上升而另个下降， 干涉将是破坏性的。

The cross-coupled inverter makes it such that these two bitlines are always going to be opposite one another.

交叉耦合反相器使得这两条位线总是彼此相反。

Now, to put this into perspective, I use a professional DSLR camera now, a real photography camera, to film my YouTube videos.

现在来说说这个， 我现在用的是专业的反相机，真正的摄影相机， 来拍摄我的YouTube视频。

It stands for single-lens-reflex. SLR cameras use a movable mirror that's placed between the lens and the film to project the image.

代表镜头-反光式相机。反相机在镜头和胶片之间放置了块可移动的镜片，以此来投射影像。

The image produced by this new camera is absolutely beautiful, and the new portrait blur emulates the wide aperture optical effect of a professional DSLR camera.

这款新摄像头产生的图像绝对漂亮，新的人像虚化模拟了专业反相机的大光圈光学效果。

So I got the DSLR to actually make videos, and my husband and I had moved up to the Catskills around that time.

- 所以我让反相机真正制作视频，而我丈夫和我大约在那个时候搬到了卡茨基尔。

Let's look again at this inverter looped back upon itself and add two more inverters into the loop, thus creating a ring oscillator.

让我们再次看看这个反相器反馈回自身的电路， 并在环路中再添加两个反相器，从而构成个环形振荡器。
