基本解释

The ocean surface mixed layer can be approximated to a vertical uniform layer on temperature, salinity and current.
海洋的上混郃層可近似爲溫度、鹽度和餘流的垂直均勻層，如同大氣的充分混郃層一樣。
Soil retention capacity of surface layer is the best in the mixed forest, while differences are little in other forests.
混交林表層土壤蓄水功能最好，其他林分各層次差異較小；
The ocean surface mixed layer plays an important role in the processes of the exchange of heat and momentum between the upper ocean and the atmosphere.
海洋上混郃層在大氣和海洋之間的水汽、熱量和動量的交換過程中有著重要的作用。
