查询词典 temperature gradient

Our results showed 1 The changes in trends of leaf traits response to the rainfall gradient differed either with species or with a specific trait; 2）The same trends were found at the functional group level, However, leaf traits for grasses tends to be less sensitive, then for forbs, and the legumes is the most sensitive functional group along the rainfall gradient, indicated that the Grass function group is quite strong to the soil moisture content tolerance, and which certainly explained to the local vegetation distribution and the substitution between species.

主要结论如下：1 叶片性状在降雨量梯度上的变化趋势在物种水平上表现出多样化的特点，性状的变化趋势是否有显著的格局取决于物种或特定性状。2 叶片性状对水分梯度的响应在功能群水平上表现出各自的特点，Grass功能群对水分梯度的响应敏感性较低，Forb居中，Legume表现出较强的敏感性，表明Grass功能群对水分的耐受性比较强，这在一定程度上解释了当地克氏针茅草原上目前以禾草类为主的现状，对物种之间的替代有一定的指示性。

The shear layer vortices dominate in the initial portion of the jet, which are a result of the K-H instability. The crossflow encounters an adverse pressure gradient ahead of the jet and separates to form horseshoe vortices under the pressure downstream, and they develop into the wake. The wake vorticity comes into being in the actions of an adverse pressure gradient and a wall-normal component of vorticity, which originates from the wall boundary and is entrained into the jet. The shear layer vortices encounter adverse pressure gradients in the lee of the jet and break down, leading to the formation of the CVP and the CVP is the most important characteristic of the jet in crossflow.

文中指出：剪切层涡源于射流与横流之间的K-H不稳定性；马蹄形涡的产生是由于射流喷口上游迎风侧的壁面边界层内存在逆压梯度，使流动发生了分离，在下游逆压梯度的挤压作用下，形成了马蹄形涡，马蹄形涡向下游发展，进入尾迹区；在逆压梯度和法向涡生成项的共同作用下产生了尾迹涡，尾迹涡源于壁面边界层，止于射流，并将部分涡量向上输运至射流内部的CVP；CVP是横向紊动射流的重要特征，剪切层涡破裂后，在逆压梯度的作用下CVP形成。
