n.傾斜度；坡度；梯度

The car slid down the steep gradient into the river. 汽車滑下陡峭的斜坡掉入河中。

The road has a fairly steep gradient. 這條路的坡度相當(dāng)陡峭。

The resulting solution is known as the gradient. 合成解就是通常的梯度風(fēng)。

Substrates may accumulate intracellularly against a concentration gradient. 底物可以逆濃度梯度而積聚于細(xì)胞內(nèi)。
