两倍

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。

Therefore, the postmasters at these two offices should exchange assignments: the Presto City postmaster will solve the problems of inefficiency and customer dissatisfaction at the Lento City office while the Lento City postmaster learns first -hand the superior methods of Presto City.

邮局办公业务的地区总监的备忘录：在为期2周的邮政操作研究中，Presto城的邮政处理的项目为Lento城的邮局两倍，虽然两个城市规模差不多，但是，P城的顾客满意度看起来更高，因为研究发现的对P邮局的抱怨要比较少。因此，两个邮局的局长应该交换位置。P城的局长将解决L城邮局的低效和顾客不满问题，而L城的局长可以从P城学习第一手的管理方法。

This product was listed on the end of 2007, incorporates the industry's original Bi-ink double-charged print head technology, two lines of black line up the print head nozzles disnature width to one-inch, print range is from the past two times, the same print area, the sprinkler head General printer requires two round trip, but an C110 to complete.
