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 streaks（modified after reference［17］） 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)
