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。

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数码单反相机。

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

所相机制造商们现在正转端的市场，数码单反相机和无反相机。

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

并且还有无反相机，它们是小型相机和数码单反相机的结合。

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

这款名为Lytro Illum的相机造型和端专业单反相机类似，定价是达到1600美元。

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

Q 是输出，Q 条是反相输出。

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

由于反相器的数量为奇数，输出在 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.

所很兴，如果需要反相输出信号，在那之后备用一个反相器。

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

它们像小型相机一样小巧，但是还在它们上面使用跟在数码单反相机上使用的一样的镜头。

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

反相器本身将输入从 1 翻转为输出 0，反之亦然。

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.

代表单镜头-反光式相机。单反相机在镜头和胶片之间放置了一块移动的镜片，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单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.

- 所我让数码单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.

让我们再次看一下这个反相器环回到自身， 并在环路中添加另外两个反相器，从而创建一个环形振荡器。

And then there are SLRs and DSLRs which are bigger, and you can change the lenses on these cameras and they allow for a lot of manual control.

然后还有体积大的单反相机和数码单反相机，并且换这些相机的镜头，并且它们允许进行很多手动控制。

The  cross-coupled inverter makes it such that these two bitlines are always going to be opposite  one another, and they're called a differential pair.

交叉耦合反相器使得这两条位线始终彼此相对，它们被称为差分对。

And there are also mirrorless cameras, which are a cross between compact cameras and DSLRs. They are small like a compact camera, but you can also use the same lenses on them that you can use on DSLRs.

同样还有无反光镜相机，它是袖珍相机和数码单反相机的结合体。它们像袖珍相机一样小巧，但是同样在它们上面使用数码单反相机所使用的镜头。

5 volts and, by having a  differential pair of active and passive bitlines, the easiest solution is to disconnect the cross  coupled inverters and open a channel between the two using a transistor.

5伏， 并且通过使用有源和无源位线的差分对，最简单的解决方案是断开交叉耦合的反相器并使用晶体管打开两者之间的通道。

Well, when the active bitline is  a 1, the passive bitline will be driven by this cross-coupled inverter to the opposite value  of 0, and when the active is a 0, the passive becomes a 1.

嗯， 当活动位线为 1 时，被动位线将由这个交叉耦合反相器驱动为 0 的相反值，而当活动位线为 0 时， 被动位线则变为 1。
