Both planets have roughly the same amount of land surface area, sustained polar caps, and both have a similar tilt in their rotational axes, affording each of them strong seasonal variability.
这两个行星都有大致相同的地表面积，都有极冠，都有类似的倾斜旋转轴，使得火星和地球都有很强的季节性变化。
The result showed that the removal efficiency was improved with larger specific surface area of particle electrodes, decreased space between polar plates and higher voltage.
结果表明，填充颗粒比表面积越大、极板间距越小、电压越高，越有利于氟离子的去除。
