• 科技英语是表达自然、思维和社会现象、原则理论和本质定 律的，因而它有平实、严谨、简明和逻辑抽象的措辞规则。 科技英语的“表达方式以抽象性、逻辑性、说理性为特征， 要求平实、严谨、简明。在语文材料和修辞手段的运用上注 重平白质实，不求华巧奇特。在思想内容和表达形式的结合 上，要求谨严切合，直接呈现科学思维的逻辑条理性，而不 运用修辞变通。在表达效果和可读性的追求上，要使人理解 ，而非使人感动，故以明晰简洁为度。用词讲究术语的专义 性、书面性和国际通用性。造句以规范完整的复合句式直陈 事理为基本格调。章法常有一定的程式，按事理的逻辑顺序 布局成文。
虽然这些分子允许可见波长的辐射——阳光的绝大部分能量就汇

• 科技英语用确切具体的词汇, 不用局限粗俗、过时 少用和敷衍邋遢的表达。如方言、俚语、行话、口 语词、废弃词、混杂词,以及笼统词或华丽辞藻。所 以,需要减少陈词滥调, 如swell, stuff, to get a hunch。当然,科技领域亦用同义文雅词来表达客观 真实或抽象内容。 如: stiff→ rigid; suitable→ appropriate; make → fabricate

cations system is first concerned with the collation, processing and storage of information before its transmission. The actual transmission then follows. Finally we have reception.
It is often convenient to vary the capacitance in a circuit without removing the capacitor. The component in Fig. 2 are fixed capacitors, since it is clearly not easy to vary their capacitance. The common variable capacitor is made of two sets of interleaved plates. One set is immobile and the other set is attached to a shaft. If we rotate the shaft, we can effectively change the area of the plates so as to change the capacitance. Because the dielectric is air and it is necessary to make the separation between plates relatively large to assure that they do not touch, maximum capacitance values are limited to about 500 pF.
