• 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.

    行星大致相同地表面积,都有极冠,都有类似倾斜旋转轴,使得火星和地球都有很强季节性变化

  • 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.

    结果表明填充颗粒表面积越大极板间距越小、电压,越有利于氟离子去除
