电化学的范围很广,在理论化学方面,有浓差电池的电动势,溶液的电导,及其它电化学性质等。这一部分已包括在物理化学的贡献中。它如有机化学、无机化学或分析化学都有电化学的应用。本文以电化学工业为主要对象,例如电分解或电合成的化学工业,金属冶炼所用电炉的设计,干电池或蓄电池的研究等。可是四十年来(1911— A wide range of electrochemical, in theoretical chemistry, the concentration of the battery electromotive force, the conductivity of the solution, and other electrochemical properties. This part has been included in the contribution of physicists. It is as organic chemistry, inorganic chemistry or analytical chemistry have electrochemical applications. In this paper, the electrochemical industry as the main target, such as chemical decomposition or electro-chemical industry, metal smelting furnace design, dry cell or battery research. But forty years (1911 -
