电化学是化学中重要的一部分 ,我们针对有关电解、原电池、溶液的导电性等实验内容设计并制作了这台电化学多功能显示器。它有三个方面的功能 :①判断溶液的导电性 ;②电解电源 ;③原电池。为实现上述三方面的功能 ,其工作电路由直流电路和音响电路两部分组成。再配上电源、波 Electrochemistry is an important part of chemistry. We designed and fabricated this electrochemical multi-function display for experiments on electrolysis, primary cells, and the conductivity of solutions. It has three functions: 1 to determine the conductivity of the solution; 2 electrolytic power; 3 primary battery. In order to achieve the above three functions, the working circuit consists of a DC circuit and an audio circuit. With power and wave
