water potential gradient的意思|示意
水势梯度
water potential gradient的网络常见释义
水势梯度 当有多个细胞连在一起时，如果一端的细胞水势较高，另一端水势较低，顺次下降，就形成一个水势梯度(Water potential gradient)，水分便从水势高的流向水势低的。植物器官之间水分流动方向就是依据这个规律。
梯度 (2) 蒸腾作用发生时，水分子由叶面蒸发，产生了一个水潜能梯度 (water potential gradient)，不断将水由茎牵引至叶面， 再由叶的木质部引至叶面，这张力状态 令水份被牵引及进入木质部。

Water potential reflects energy level of soil water and the gradient of water potential is an impotent factor describing direction and velocity of water flow.
水势反映土壤水的能态，而水势梯度则是决定水流方向和速度的重要因素。
Affected by hydraulic potential gradient, the unsaturated soil water in the furrow soil may supply laterally the ridge soil of adjacent furrow.
受水势梯度的影响，犁沟内非饱和水可以侧向补给相邻畦埂的土壤。
Meanwhile, by the influence of water vapor in the process of heating, the gradient of equivalent potential temperature weakened, and baroclinic term also declined, so the total MPV increases.
同时，在此过程中受水汽加热的影响，水平相当位温梯度减弱，负的斜压项减弱，使得总的湿位涡正值增大。
