这是原文一部分，有点长，我用在线翻译和软件翻译都试了，差太多。先谢谢各位啦，之后追加50分，谢谢啦。！！！
By the end of the 1930’s, Willem Elenbaas (Philips, the
Netherlands) theoretically predicted a rise of mercury lamp efficacy
with the increase of the arc power loading. This was effectively
verified after the invention of quartz-to-tungsten graded seals in 1935
(Cornelis Bol - Philips). The next year, Philips was then able to market the first low-power high-pressure
(20 atmosphere) lamp, the HP300 (75W). This was followed by a breakthrough source: the water-cooled
SP500W working at 80 atmospheres (Philips). Not only these lamps had a better efficacy (40 and 60 lm/W
respectively), they also showed improved color rendering properties owing to the higher operating pressure.
The SP500W lamp was primarily designed and
used for film projection and floodlighting
applications, while the HP300 remained favored for
street and industrial lighting due to its still
insufficient emi

手工翻译不好找啊~~
我做毕业论文翻译时的方法，挺不错的。
前提，PDF要是非图片格式的（就是说用阅读器打开后可以用鼠标选中文字的）。
关键是要把PDF变成文句通顺的WORD格式，然后用google在线翻译就行了。
第一步，把PDF变成txt。（因为直接拷到word里准确度太低了）
第二步，把txt考到word里，改好格式（主要是去掉多的回车符，调整空格）。用拼写检查修改不准确的地方，使文档通顺。
第三步，把修改好的文档用google在线翻译译成中文。
最后，把文档修改好。
祝你好运！！
