一、电极制作将八块牙膏皮(铅锡合金的而非铝质的)剥开后,先用热烧碱溶液洗去表面的油漆,再用砂纸打磨,就制得了铅箔。将四块铝箔铺成一排,使其首尾相接,前一块压住后一块一厘米。再用第一块铅箔将一根直径0.5厘米的玻璃棒(或园筷子)卷在里面。在铅箔上铺一张与它等宽,但比整个铅箔条稍长的糊窗户纸(也可用吸墨水纸或卫生纸
First, the electrode production will be eight pieces of toothpaste leather (lead-tin alloy instead of aluminum) peeled off, first with hot caustic soda solution to wash off the paint on the surface, and then sanding, to produce a lead foil. The four aluminum foils are laid in a row and they are connected end to end. The front piece is pressed one centimeter behind. Then use a lead foil to wind a 0.5 cm diameter glass rod (or chopsticks) inside. Spread a sheet of lead paper on the lead foil that is equal in width but slightly longer than the entire lead foil. (You can also use ink blotting paper or toilet paper.)
