摘要或動機

本文所探討的議題為電解質溶滿通以電流後所產生的效應與機制。本實驗所採用的方法為電解與電鍍,運用這兩種方法,來比較電解液在不同狀況下所產生的結果;經過多次的實驗,累積了許多實驗結果,使我們可以得到更精確的數據 · 在此次實驗中,我們發現電解液在相同的電壓下,通以電流後的穩定性與金屬的活性有關,活性越大越不穩定;反之,活性越小越穩定。另一個發現為,只有單一極性離子移動的情形,可通過的電流,比陰陽離 r 同時移動時為大;但因通過的電流大使電解液反應劇烈,產物時時覆蓋電極使電流下降。所以就穩定性來說,是以陰陽離子同時移動為佳 · 在展望方面,希望可以發展到液態磁屏避的設備,可減少設備過重之問題 ·This is a study of how electric current effects the electrolyte solution. The experiment was conducted through two methods: electrolysis and electroplating, the results of which were compared. The experiment of the same designs hi been conducted repeatedly and, as a result, accurate data were collected and accumulated.One of the two major findings from the experiments was that, when under the same voltage, stability of the electric current varied with the change of activity of the metals; the greater the activity of the metals, the less stability of the current, and vice versa. The other major finding was that, with the movement of dipole-ion, a greater amount of current would go through the solution than that which would go through with the movement of cathode and anode; however, the greater amount of current would cause intense reaction of electrolyte solution, hence merging the electrode and reducing the current. So as long as stability is concerned, the movement of cathode and anode is preferable.It is hoped that more sophisticated experiments designed on the basis of the similar principles will eventually lead to the construction of equipment of liquid-magnetic shielding of smaller weight and size.
