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。

This thesis discusses mainly the hardware design and development of a simulator for airborn phase array radar. The long period of the simulator is implemented by SDRAM MODULES used in Personal Computer, the broadband is implemented by D/A with internal double-data-channel switching architecture, and the control is implemented by a single CPLD.

本文主要探讨了一种机载相控阵雷达回波模拟器的硬件设计和工程实现，采用了PC机内存常用的超大容量高速缓存SDRAM MODULES来实现输出信号的长周期，采用内部具有双路数据分时切换结构的D/A实现输出信号的宽带，采用一片CPLD完成整个系统的时序逻辑控制。

The 151st Airborn Tank Company was not available in time for deployment with airborn units on D-Day,and in July 1944 was transferred from Ft.Knox to Camp Mackall,Noth Carolion, where in was quickly forgotten.

第151空降坦克连没有及时有效的作为一支空降部投入到D日的作战当中，在1944年的6月从诺克斯堡运到了北卡罗来纳的麦考尔训练营并很快的在那里被遗忘。
