hypolimnion

hypolimnion

1. Hypolimnion The lower noncirculating water in a thermally stratified lake.

下层滞水层，均温层：在热层结湖中位置较低的不循环水层。

2. metalimnion A zone of abrupt temperature change (thermocline) between the warm epilimnion and the cool hypolimnion of a lake.

变湖层在湖的温暖表水层与冷的深水层之间的一个突然温度改变(斜温层)的区域。

3. In many lakes in summer that is a warm low-density layer (EPILIMNION) lying above a colder denser layer (the HYPOLIMNION), the zone of rapid temperature change between the two layers being celled the thermocline.

夏季，多数湖中温暖的低密度水层（湖面温水层）在寒冷的较高密度水层（湖底净水层）之上，中间夹有温度改变较快的水层（变温层）。

4. hypolimnion The cold lower layer of a straitfield lake, under the epilimmion and beginning just below the thermocline. This layer is not directly affected by surface events.

斜温层下水分层湖的寒冷低层，在斜温层上水下方与斜温层正下方开始。这一层并不直接被表面事件影响。
