【正文】 ed in 1931.Founded in 1931, Xidian University is one of the national key universities in China.One of the national key universities in China, Xidian University was founded in 1931.26. 交流電能轉換成直流電，這一過程稱為整流。Because puters are accurate in operation and high in speed, they found wide application in all fields.Accurate in operation and high in speed, puters have found wide applications in all fields.24. 本文介紹了一種測溫新方法，重點放在其基本原理上。Then a problem arising, blind speed.Then the problem of blind speed arises.22. 我們通常使用像電阻器、電容器、電感器等元件。 exist。 …occur。 arise from。Capacitor is a device consisted of two conductors which are separated by a insulator.A capacitor is a device consisting of two conductors separated by an insulator.consist of。Semiconductors are very sensitive to light and heat, and both the factors effect their conductivity greatly.Semiconductors are very sensitive to light and heat, both of which have a great effect on their conductivities.19. 用這種方法所導出的數(shù)學模型證明是簡單而實用的，從而為最佳設計創(chuàng)造了良好的條件。 pair。 form。 a new kind [type。 the northeast。The other two problems will be discussed in detail later.The two other problems will be discussed in detail later.iron and steel。The information contained in [by] this signal is three times more than that signal.The information contained in [by] this signal is four times more than that contained in [by] that signal.This signal contains four times more information than that one (does).*** China has several times as large an area as France (does). 16. 其余的[剩下的]問題以后再討論。At last [In the end], we provided some problems that should be noted in implementing this method and solving ways.Finally, some problems that deserve to be noted in implementing this method and their solutions are given.14. 本文提出了估算多普勒調(diào)頻率的一種新方法，其精度高、計算量少。The mathematical description and the fullpensation condition of the 3axes steadytracking principle are also given.A mathematical description of and the fullpensation condition for the 3axis steadytracking principle are also given.12. 這位教授在研究和應用圖像處理方面起了重要作用。This is due to that there exists a capacitance on the PN junction.This is due to the fact that there exists a capacitance across the PN junction. [This is due to the existence of a capacitance across the PN junction.]10. 我們只需要測量這個元件上的電流和電壓。There are M polygons in all, whose vertex number is all N.There are M polygons in all [altogether], the number of vertexes of each of which is N [each of which has N vertexes].8. 對構件承載能力作了具體的分析。 leads to] C.6. 這個方法需要精確的定位，這就使得它的實現(xiàn)具有一定的難度。 produces。If A is substituted in B, we get C.Substituting A in [into] B, we have [get。 give rise to。 occur] in the LC oscillator.A poor [An improper] design of the bias circuit will lead to [result in。If the bias circuit does not design good, the LC oscillator will occur chopping oscillations.If the bias circuit is not designed well [properly] (If the bias circuit is of poor design), chopping oscillations will take place [result。The model successfully explains the experiment curves of the base surface current varying with the gate current.The model explains successfully the experimental curves of the variation of the base surface current with the gate current.

This algorithm can lead to the reduction in the amount of putation.”我們可以把它改寫成“This paper presents a new algorithm, which can lead to the reduction in the amount of putation.”又如：“本文介紹了一種新的CAD設計方法, 重點放在其基本原理上。（由于我們漢語中的句子一般比較短，所以不少人在撰寫英語科技論文時喜歡用不少簡單句或并列句，使文章顯得很松散?！睉獙懗伞癐t was realized at that time that light is a kind of electromagnetic wave.”一般不要寫成“People realized at that time that …”?！蓖鶎懗伞癐t is desired to develop this function into a Fourier series.”（當然我們也可使用主動句“We wish to develop …”）?！盩his is what is referred to as acupuncture.二、科技英語寫作的主要特點*** Main features of scientific writing:1. long but simple sentences by often using phrases instead of clauses （句長而簡單）2. pact instead of loose（緊湊而不松散）3. sentence patterns preferred by scientists and engineers（句型）4. impersonal expressions (so passive voice is widely used)（無人稱句）廣泛使用被動句 由于科技文主要涉及科技事實，所以往往不需要涉及具體的人，因而被動句使用得比普通文章中
