在觀察電壓-時間（V-T）圖的同時，它也可以提供圖4中這三種電解液樣品

While observing the voltage-time (VT) diagram, it can also provide a view of the trend change of the surface roughness of the three electrolyte samples in Figure 4. It can be seen that the surface roughness values ​​of the SEHi and SEH samples (up to 1.8μm) are higher than those of the SE sample (1.577±0.063μm). It is speculated that the higher the breakdown voltage and the voltage in the critical voltage region, the more intense the entire discharge process, leaving more holes and ridges on the surface of SEHi and SEH samples.

While observing the voltage-time (V-T) graph, it can also provide an idea of the change in surface roughness trend of the three electrolyte samples in Figure 4. As can be seen, the surface roughness values of both SEHi and SEH samples (up to 1.8 m) are higher than those of SE samples (1.577±0.063 m). It is assumed that the higher the voltage in the knockout voltage and critical voltage zone, the stronger the entire discharge process, leaving more holes and ridge lines on the surface of the SEHi and SEH samples.

While observing the voltage time (V-T) diagram, it can also provide the view of the surface roughness trend of the three electrolyte samples in Fig. 4. It can be seen that the surface roughness values of sehi and sEH samples (up to 1.8 μ m) are higher than that of Se samples (1.577 ± 0.063 μ M). It is speculated that the higher the breakdown voltage and the voltage in the critical voltage region, the stronger the whole discharge process is. In the sehi and sEH samples, the higher the breakdown voltage and the voltage in the critical voltage region are, the stronger the discharge process is More holes and ridges are left on the surface.<br>
