The other type is the transmission electron microscope, or TEM.

另一种是透射电子显微镜，或简称透射电镜。

He ended up as President pro tem after George Clinton passed away.

在乔治·克林顿去世后，他最终担任了临时院主席。

Let's first focus on the TEMs as they are more commonly used in developing cutting-edge technology.

让我们先关注透射电子显微镜，因为它们在开发前沿技术方面更为常用。

We just let the president pro tem do the job.

我们只是让临时总统来处理这件事。

How was your TEM this time?

这TEM怎样?

For example, TEMs are used to take the pictures of these sections of a transistor.

例如，透射电子显微镜用于拍晶体管这些部分照片。

If the vice president is unavailable, then the president pro tem of the Senate is kind of the backup for that.

如果副总统无法履职，那院临时主席就相当于这个职位后备人选。

Additionally, a useful variation of the transmission electron microscope that's worth mentioning is called an S-TEM, where the S is for scanning.

此外， 还有一种有用透射电子显微镜变体值得一提， 称为S-TEM，其中S代表扫描。

The senators also elect a president pro tem who acts as the president of the Senate when the vice president of the United States cannot participate.

当美国副总统不在场时，员也可以选出院临时主席代行主席职务。

The best cure is for everyone to try to make his own assumptions explicit and beg the others to accept them pro tem.

最好治疗方法是每个人都尝试明确自己假设并恳求其他人立即接受它们。

The chief justice will be sworn in by the longest-serving member of the Senate, known as the president pro tem of the Senate. That's Senator Chuck Grassley.

首席大法官将在院任职时间最长员主持仪式上宣誓就职，这名员是院副长查克·格拉斯利。

More expensive TEMs typically have the optical elements and circuitry to perform both TEM and STEM, and the user can toggle between the two modes.

更贵透射电子显微镜通常配备有执行透射电子显微镜和扫描透射电子显微镜所需光学元件和电路，用户可以在两种模式之间切换。

The basic idea behind a TEM is that it generates electrons and accelerates them to around 70% the speed of light, thus creating a beam of electrons.

透射电子显微镜基本原理是生成电子并将其加速到接近光速70%，从而形成一束电子。

This microscope is similar to the TEM, but like the SEM, we focus the beam into a spot and then use deflection coils to scan the spot through the specimen.

这台显微镜与透射电子显微镜类似，但像扫描电子显微镜一样， 我们将束聚焦成一个点， 然后使用偏转线圈使该点在样品上进行扫描。

However, in other domains of science, TEMs can be used to take images of proteins inside mitochondria, the powerhouse of the cell, or of nanoparticles of pure gold.

然而， 在科学其他领域，透射电子显微镜可以用来拍线粒体内蛋白质图像，线粒体是细胞能量工厂， 或者拍纯金纳米粒子图像。
