图3 风条痕特征参数的定义(据参考文献[17]修改)
θ是风条痕的角宽度,指风条痕张开的最大角度;?是风条痕的伸展方向,从正北方向顺时针旋转至角宽度的平分线处所对应的角度
Fig.3 Definition of characteristic parameters of wind streaksmodified after reference17])
θ is the angular width (maximum whole angle measured along the sides of the streak); ? is the direction of wind streaks (defined as the bisector of the angular width from north)
