剩下的10%主要来自于植物的蒸腾作用。

Most of the remaining 10% is released by plants through transpiration.

气温和蒸气压不足是影响蒸腾作用的关键因素。

Air temperature and vapor pressure deficit were the key factors affecting transpiration.

由于其本质是脂类，因而角质是疏水的，可以帮助减少蒸腾作用。

Being fatty in nature, cutin is water-repellent, therefore helping to reduce transpiration.

白天蒸腾作用散失的水分超过根系吸收的水分，因而叶子的水势就下降。

During the day water loss by transpiration exceeds water absorption by the roots and leaf water potential decline.

在胸中结合自然界的清气，又在心阳的温煦蒸腾作用下，化生为红色的血液。

Combined with the fresh air inhaled into the lung, warmed and steamed by heart-Yang, these refined nutrients are transformed into red blood.
