敢“捉”雷电的人 1752年6月的一天,美国著名科学家富兰克林冒着生命危险,用风捕捉到了天空的闪电,当携带雷电的乌云来到风筝上方时,风筝上方细的铁丝立即从云层中“捕捉”电荷,当这些电荷传到被雨水浸湿了的风筝及其绳索上时,绳索上的松散纤维就向四周直立起来,并且电荷能从手指传遍全身,富兰克林用自己的身躯证实了闪电就是一种短暂的电流,并在一年后制造出了世界上第一个避雷针,富兰克林是幸运的,1753 年,俄国科学家罗蒙诺索夫和他的朋友利赫曼也试图用类似方法“捕捉”闪电时,利赫曼不幸遭电击身亡。
One day, in June 1752, the famous American scientist Franklin risked his life and caught the lightning of the sky with the wind. When the dark cloud carrying lightning hit the top of the kite, the fine iron wire above the kite immediately fell from the clouds. In the “catch” of the charge, when these charges were transmitted to the kites and ropes that had been soaked by the rain, the loose fibers on the ropes stood upright, and the charge could spread throughout the body from the fingers. Franklin confirmed with his own body. Lightning was a short-lived current, and after one year it produced the world’s first lightning rod. Franklin was lucky. In 1753, the Russian scientist Lomonosov and his friend Lichman tried to use similar When the method “catch” lightning, Lichman was unfortunately killed by electric shock.
