科研人员称,其中最重要的因素是水合,指皮肤吸收水分、保持湿度的过程。
The team believes one of the most important factors is hydration - the way skin collects and retains moisture.
因为温暖的空气比冷空气能容纳更多的湿气,所以只有当大气中的水蒸气量随着温度的升高而增加时,相对湿度才会保持不变。
Because warm air can hold more moisture than cool air, the relative humidity will be constant only if the amount of water vapor in the atmosphere increases as the temperature rises.
土壤中的有机碳是土壤是否能够保持湿度,提供营养和维持生产能力的重要指标。
Soil organic carbon is a key indicator of how well soil will hold moisture, provide nutrients, and remain productive.
