编輯同志: 物理通報1954年12月號登載了朱明生同志写的“在初中進行歐姆定律的教學的一點體會”一文,我对于其中关于引用歐姆的另一定义来解释公式(i=U/R的由來有不同的意見,現在写在下面: 我們知道,歐姆的另一定義,顯然是從歐姆定律推導出來的,也就是先有一系列的實驗基础证明欧姆定律i=U/R的真實性,然後才能导出歐姆的另一定義(歐姆的規定已在課文33頁講過)。因此歐姆的另一定義,只能由歐姆定律來决定,而歐姆定律决不能由歐姆的另一定義來驗证,這是不難理解的,现在朱明生同
Editorial Comrade: The Bulletin of Physical Education, December 1954, published in Comrade Zhu Mingsheng’s article “A Little Understanding of Teaching Ohm’s Law in Junior High Schools,” I explain another formula in which I refer to Ohm (i = U / R We now know that the other definition of Ohm is obviously derived from Ohm’s law, that is, there is a series of experimental foundations that prove the truth of Ohm’s law, i = U / R, Then another definition of ohm can be derived (the ohm rule has been quoted on page 33). Thus another definition of ohm can only be determined by Ohm’s law, which can never be verified by another definition of Ohm , It is not hard to understand, and now Zhu Mingsheng same
