两倍的

If the observer is at a great distance compared to the other dimensions of the experiment and the rays are nearly perpendicular to the reflecting surfaces, then the path difference between the two waves (corresponding to r1-r2 in the preceding section) is just twice the thickness d of the air wedge at each point.

如果观察者比起实验装置来讲距离较远而且光线较接近于垂直反射于表面，那么这两光波的光程差(在前面所述的相应部分 r1-r2)就仅仅是空气劈尖在该点处的厚度 d 的两倍。
