SAT写作经典事例：赫兹

　　本文将为大家介绍著名物理学家赫兹。他证明了电磁波的存在以及光是一种电磁波。现在电磁波频率的单位就以他的名字命名。他的发现为无线电通讯的出现起到了巨大作用。

　　As is commonly believed, Heinrich Rudolf Hertz is most renowned for being the first one to conclusively prove the existence of electromagnetic waves. He clarified and expanded the electromagnetic theory of light that had been put forth by James Clerk Maxwell. As a physicist, Hertz maintained a spirit of exploration and insistence, and his story inspires people who intend to pursue contributions in the sphere of science.

　　众所周知，海因里希 鲁道夫 赫兹因他第一个结论性地证明了电磁波的存在而出名。他阐明并扩张了由詹姆斯 克拉克 麦克斯韦提出的光电磁理论。作为一名物理学家，赫兹始终保持着探索精神和坚持不懈的精神。他的故事不断激励着想在科学领域做出贡献的人们。

　　At that time, people firmly believed Maxwell s theory of electromagnetism, that is, electromagnetic waves existed and moved at the speed of light, and light itself was just a wave. Though it was popular, the theory was still only a prediction. Encouraged by his mentor, Hertz was to prove it. He made many experiments and finally managed to make a precise wave-detecting apparatus, though he failed multiple times before success. In the experiment, he discovered the electromagnetic wave. In more advanced experiments later on, he measured the velocity of electromagnetic radiation and found it to be the same as the light s velocity. He also showed that the nature of radio waves reflection and refraction was the same as those of light and established beyond any doubt that light is a form of electromagnetic radiation obeying the Maxwell equations.

　　在他的年代，人们坚信麦克斯韦的电磁理论，也就是，电磁波是存在的，它以光速运动，而光不过也就是一种波而已。虽然这个理论很流行，但它毕竟只是一个猜想。赫兹受他的导师鼓舞，决定去证明这个理论。他做了许多实验，在失败了多次之后，终于成功制作出一个精确的测波仪。在这个实验中，他发现了电磁波;而在紧接下来的更深入的实验中，他又测出了电磁波的速度，发现确实和光速一致。他还发现无线电波的反射和折射的本质和光是一致的，并因此证明了光是一种电磁波，就和麦克斯韦方程中描述的一样。

　　With his insistence, Hertz was definitely a legend in science. His experiments soon triggered the invention of the wireless telegraph, radio and television.

　　因为他的坚持，赫兹成为了科学史上的传奇。他的实验不久就引发了无线电报，收音机和电视的发明。

　　当大家需要在文章中使用关于热爱科学、坚持不懈、战胜挫折等的事例时，不要再千篇一律地使用爱迪生啦!物理学家赫兹的事例或许能让你的文章与众不同，脱颖而出。
