21、动语态多科技英语的主要目的是表达科学发现、科学事实、实验报告科技英语的主要目的是表达科学发现、科学事实、实验报告和各类说明等，以客观陈述为主，因此科技英语大量使用被和各类说明等，以客观陈述为主，因此科技英语大量使用被动语态。如：动语态。如：It is essential that the overall program strategy It is essential that the overall program strategy be be completely mapped outcompletely mapped out before any of the detailed befo

34、电压的值也要与频率成正比变化。一般来说，必须使用一种来说，必须使用一种静电功率变频器静电功率变频器从从固定多向交流干线固定多向交流干线中产生变频及可变多相中产生变频及可变多相输出电压值，有两种方法可达到此目的。一种是使用所谓的环状变频器直接完成输出电压值，有两种方法可达到此目的。一种是使用所谓的环状变频器直接完成转换（从交流道直流）。另一种，也是更为常见的一种，即先将转换（从交流道直流）。另一种，也是更为常见的一种，即先将固定交流固定交流转换为转换为可变直流可变直流，再将该直流电压重新转换为所要的可变交流系统，该方法使用直流连，再将该直流电压重新转换为所要的可变交流系统，该方法使用直流连接。在

35、此情况下，在直流到交流的硅控整流管变频器中不能自然产生接。在此情况下，在直流到交流的硅控整流管变频器中不能自然产生负的阳极负的阳极-阴阴极电压极电压。因此，必须使用强制整流过程。常用的两种。因此，必须使用强制整流过程。常用的两种强制蒸馏逆变器强制蒸馏逆变器是所谓的是所谓的并并行逆变器行逆变器和和脉宽调至逆变器脉宽调至逆变器。4)4)非谓语动词多非谓语动词多科技英语力求简洁明了，大量使用非谓语动词。如：科技英语力求简洁明了，大量使用非谓语动词。如：Radial Keratotomy(RK)and Photorefractive Keratectomy(PRK)are Radial Keratot

36、omy(RK)and Photorefractive Keratectomy(PRK)are other refractive surgeries usedother refractive surgeries used to reshape to reshape the cornea.In RK,a the cornea.In RK,a very sharp knife is used very sharp knife is used to cutto cut slits in the cornea slits in the cornea changingchanging its its sh

38、 between the two is used for LASIK and PRK.The major difference between the two surgeries is the way that the stroma,the middle layer of the surgeries is the way that the stroma,the middle layer of the cornea,is exposed before it is vaporized with the laser.In PRK,cornea,is exposed before it is vapo

39、rized with the laser.In PRK,the top layer of the cornea,the top layer of the cornea,called called the epithelium,is scraped away the epithelium,is scraped away to exposeto expose the stromal layer underneath.In LASIK,a flap is cut in the stromal layer underneath.In LASIK,a flap is cut in the stromal

40、 layer and the flap is folded back.the stromal layer and the flap is folded back.其他用于角膜重新塑性的外科手术还有放射状角膜切开术（其他用于角膜重新塑性的外科手术还有放射状角膜切开术（RKRK）和）和光型折射角膜切削术（光型折射角膜切削术（PRKPRK）.放射状角膜切开术使用锋利的刀在角放射状角膜切开术使用锋利的刀在角膜上割开狭长的切口来改变其形状。光型折射角膜切削术使用激光膜上割开狭长的切口来改变其形状。光型折射角膜切削术使用激光塑形，它是最早的重塑角膜的外科手术。通常激光辅助原位屈光性塑形，它是最早的重塑角膜

41、的外科手术。通常激光辅助原位屈光性角膜成形术和光性射角膜切削术使用的激光完全一样。这两种手术角膜成形术和光性射角膜切削术使用的激光完全一样。这两种手术的区别主要在于，在激光蒸发基质的区别主要在于，在激光蒸发基质角膜的中间部分角膜的中间部分之前，之前，基质显露的方式不同。光性射角膜切削术使用的方法是削去角膜的基质显露的方式不同。光性射角膜切削术使用的方法是削去角膜的顶层，又称上皮层，来显露下面的基质层。而激光辅助原位屈光性顶层，又称上皮层，来显露下面的基质层。而激光辅助原位屈光性角膜成形术使用的方法是切入基质层，创建一个折边，再将折边反角膜成形术使用的方法是切入基质层，创建一个折边，再将折边反转

42、过来，露出基质层。转过来，露出基质层。5)长句多这是因为在阐述科学事实，科学现象等事物的内在联系和解释一些科技术语或名词时，需要大量使用各种从句以及介词短语、形容词短语、分词短语或副词等做后置定语，分词短语表示伴随情况等。Nanotechnology has become a buzz word in the popular Nanotechnology has become a buzz word in the popular press.The roots of this phenomenon reach back to a press.The roots of this phenomen
