9. However, instead of lenses made of glass, the transmission electron microscope uses electromagnets as lenses, as do all electron microscopes.(TPO38-P1)

但是,与光学显微镜不同的是,它不是用玻璃作为镜片,而是使用电磁体作为镜片,正如所有的电子显微镜一样。

10. Specimens are cut into extremely thin sections, and the transmission electron microscope aims an electron beam through a section, just as a light microscope aims a beam of light through a specimen.(TPO38-P1)

样本被切割成极其薄的切片,透射电子显微镜将电子束穿透切片,正如光学显微镜将光束透过样本一样。

11. The transmission electron microscope, on the other hands, is used to study the details of internal cell structure.(TPO38-P1)

另一方面,透射电子显微镜被用来研究细胞的内部结构。

12. The scanning electron microscope produces images that look three-dimensional.(TPO38-P1)

扫描电子显微镜的成像看起来是三维立体的。

13. Biologists use the scanning electron microscope to study the detailed architecture of cell surfaces.(TPO38-P1)

生物学家使用扫描电子显微镜研究细胞表面的具体构造。

14. Only under special conditions can electron microscopes detect individual atoms. (TPO38-P1)

15. In fact, the most powerful modern electron microscopes can distinguish objects as small as 0.2 nanometers, a thousandfold improvement over the light microscope.(TPO38-P1)

实际上,现代最先进的电子显微镜能够识别直径为0.2纳米的物体,比光学显微镜进步了成千倍。

16. Instead of light, the electron microscope uses a beam of electrons and has a much higher resolving power than the light microscope.(TPO38-P1)

不再利用光线,电子显微镜利用的是电子束而且比光学显微镜具有更高的分辨率。

17. Our knowledge of cell structure took a giant leap forward as biologists began using the electron microscope in the 1950s.(TPO38-P1)

直到二十世纪50年代,由于电子显微镜的使用,我们对于细胞结构的了解实现了巨大飞跃。

18. From the year 1665, whenEnglish microscopist Robert Hooke discovered cells, until the middle of thetwentieth century, biologists had only light microscopes for viewing cells. (TPO38-P1)

从1665年英国显微镜学家Robert Hooke发现细胞到二十世纪中期,生物学家只能通过光学显微镜来观察细胞。

19. The light microscope cannot resolve detail finer than 0.2 micrometers, about the size of the smallest bacterium; consequently, no matter how many times its image of such a bacterium is magnified, the light microscope cannot show the details of the cell's internal structure.(TPO38-P1)

光学显微镜不能够分辨小于0.2微米的细节,这相当于最小的细菌的大小;因此,不论这个细菌被放大了多少倍,光学显微镜都不能展现出细胞内部结构的细节。

20. Light microscopes can magnify objects up to1,000 times without causing blurriness.(TPO38-P1)

光学显微镜能将物体放大1000倍而不会模糊不清。

21. Glass lenses in the microscope bend the lightto magnify the image of the specimen and project the image into the viewer'seye or onto photographic film.(TPO38-P1)

显微镜中的玻璃镜片通过弯曲光线将样本放大,并将样本的影像投进观察者的眼中或者感光胶片上。

22. The first microscopes were light microscopes, which work by passingvisible light through a specimen.(TPO38-P1)

第一代显微镜是光学显微镜,其工作原理是将可视光透过样本。

23. Before microscopes werefirst used in the seventeenth century, no one knew that living organisms werecomposed of cells.(TPO38-P1)

在17世纪显微镜第一次投入使用之前,人们都不知道生物体是由细胞构成的。

24. And as microscopes improved, we discovered some microorganisms that were incredibly small.(TPO50-L2)
