图10. $\nabla ^2\bar{{V}}$ 与 $r^\ast $ 的对应关系. (a) 软区的 $\nabla \bar{{V}}$ 场与四极非仿射位移的对称关系, (b) 仅 $x $方向上梯度大, (c) 仅 $y $方向上梯度大,(d) 仅 $y = x$ 方向上梯度大, (e) 仅 $y = - x$ 方向上梯度大
Fig. 10. The relationship between $\nabla ^2\bar{{V}}$ and $r^\ast $. (a) Symmetry between $\nabla \bar{{V}}$ of soft region and quadrupolar nonaffine displacement. (b) Large gradient only in the $x$ direction. (c) Large gradient only in the $y$ direction. (d) Large gradient only in the $y = x$ direction. (e) Large gradient only in the $y = - x$ direction
