President Barack Obama said a'catastrophic breach'allowed the alleged Christmas Day bomber to set his attack into motion, as it emerged that multiple U.

Successful attack would advance our bomber bases still farther.

进攻成功，可扩张我们的轰炸基地。

Optical observation sight is a dominating air-ground attack method to a large or medium bomber, which its optical systems are usually chosen telescope. The telescope should demand two bands spectrum of visible light and near infrared.

光学观测瞄准是大中型轰炸机主要的对地攻击瞄准方式，其光学系统一般采用望远式光学系统，这就要求光学系统能满足可见光和近红外光两个光谱波段。

The accident report made no mention of nuclear weapons aboard the bomber.

对事故的报道没有提及轰炸机上面的核武器。

The correspondent aroused, heard the crash of the toppled crests. He bore down on the accelerator and the truck roared through its course like a heavy bomber.

记者醒了，他听见了浪头倒塌下来的轰隆轰隆声。他踩下油门，卡车象重型轰炸机似地轰然开过。

Each deployed heavy bomber equipped with nuclear arms counts as just one warhead, and both countries have already been cutting above their current treaty obligations.

每架已部署的挂载核武的重型轰炸机只算一个核弹头，而目前两国各自已经在削减的核武数量，超出它们当前的条约义务。

He bore down on the accelerator and the truck roared through its course like a heavy bomber.

他踩下油门，卡车像重型轰炸机似地轰然开过。

Because many weapon systems, such as aircraft carrier battle group, ballistic missile, cruise missile, long-range fighter-bomber, etc., are various kinds of moving targets.

许多武器系统本身就是运动目标，如航母战斗群、弹道导弹、巡航导弹，远程战斗轰炸机等。

Cr-Cu-N films were deposited using low energy ion beam assisted magnetron sputtering ( IBAMS). The effects of copper and bombardment energy on structure, hardness and fracture toughness of the films were studied.

应用低能离子束辅助磁控溅射（IBAMS）沉积铬-铜-氮薄膜，研究了铜含量和轰击能量对薄膜结构、硬度和断裂韧度的影响。

The added copper had no obvious effects on the film structure and hardness at same bombardment energy of 400 eV. But added copper was beneficial to improvement of the film fracture toughness.

结果表明：在相同的轰击能量（400eV）下，铜含量对薄膜结构和硬度的影响不明显，但是铜的加入有利于提高薄膜的断裂韧度；

When the ion bombardment energy was increased from 400 eV to 800 eV, the film structure was changed remarkably and its fracture toughness and hardness were improved further.

离子辅助轰击能量从400eV增加到800eV时薄膜的结构发生了显著变化，断裂韧度和硬度均大幅度提高。
