| 説明 | The surface of the leaves are perfectly smooth on a nanoscale. Since there are no microscopic crevices or pits for the water to sink into and adhere to, the water rolls off the leaves.. The surface is hydrophobic. 1 nanometer equals 1 billionth of a meter. A DNA double-helix has a diameter of about 2 nanometers. |
