图4 细长柔性植株和刚性圆木棒周围地表剪应力减小区域（A）和增加区域（B）的比较（ $τ_{s 0}$ 为来流地表剪应力， $τ_{s} / τ_{s 0}$ 为局部地表剪应力与来流地表剪应力的比值）

Fig.4 Comparison of areas of decreased （A） and increased （B） surface shear stress between slender flexible plant and rigid round stick （ $τ_{s 0}$ is the incoming surface shear stress， $τ_{s} / τ_{s 0}$ is the ratio of local surface shear stress to the incoming surface shear stress）
