一、放电现象 --类比猜测 1743年～1744 年间,美国物理学家 富兰克林在费城和 波士顿看到了来自 苏格兰的斯宾塞 (A.Spence)博士利 用玻璃管和莱顿瓶所做的简单的电学实验时,心里 激起了强烈的探求欲望。他买下了全部展品,开始 研究电学问题,一位他在伦敦英国皇家学会结识的 朋友柯林森(Peter Collinson)得知此事后,给富兰克 林寄来了一批电学著作、莱顿瓶和一些摩擦起电的 设备,并在信中介绍了使用方法。富兰克林就用它 做了一系列实验,他根据自己所观察到的实验现象, First, the phenomenon of discharge - analogy guess From 1743 to 1744, the American physicist Franklin saw in Philadelphia and Boston, Dr. Spencer from Scotland using glass and Led Dayton made simple electrical Experiment, my heart provoked a strong desire to explore. He bought all the exhibits and began to study the electrical problem. After one of his friends, Peter Collinson, who met at the Royal Society of London, learned of the incident, he sent Franklin some electrical books, Electrical equipment, and introduced the use of the letter. Franklin used it to do a series of experiments, he observed under the experimental phenomenon,
