您要查找的是不是：
- twice reflected beam 二次反射束
- A method to calculate the aberration of the reflected beam of corner cube retroreflector(CCR) is introduced. 提出一种计算角锥棱镜反射光束相位误差的方法。
- Besides,whether the incident beam is elliptically polarized or linearly polarized(with polarization state other than TE or TM),the reflected beam will exhibit a transverse shift. 另外,反射光束不仅在椭圆偏振态入射的情况下会产生横向位移,而且在TE和TM偏振态之外的其他线偏振态入射时,也会产生横向位移。
- Satellite retroreflector is used as laser ranging cooperative target to improve the intensity of reflected beam, which has close relationship with processing parameters of the retroreflector. 卫星角反射器作为激光测距系统中的合作目标, 其主要作用在于提高地面接收机范围内反射光束的能量密度。
- Depending on the nature of the reflecting objects, the intensity of the reflected beam will vary. 随着反射目标的性质不同，反射回来的波束强度也就不同。
- When an acoustic beam, limited both in time and space, radiated from liquid to a plane lipuid solid interface, we observed the nonspecular reflection phenomena (the reflected beam has a fixed reflected angle in some range of incident angle). 当时间·空间上有限的声束入射到液固平界时，我们观察到非镜面反射现象（即在一定入射角范围内有一个以固定角反射的反射波）。
- The flight to Accra goes twice a week. 飞往阿克拉的班机一星期开两班。
- We should brush our teeth at least twice a day. 我们每天应该至少刷两次牙。
- I am more than twice as old as he. 我的年龄是他的两倍还不止。
- Jack was fired twice but both times taken back. 杰克曾两次被解雇，但两次都被允许回去工作。
- The filly has been raced twice this season. 这匹小牝马本季度曾两次参赛。
- Her sad looks reflected the nature of her thoughts. 她面带忧伤显出心事重重。
- She performed on the balance beam with much grace. 她在平衡木上表演得非常优美。
- If I wee you, I'd think twice about it. 如果我是你我会三思而后行。
- A reflected signal on a communication channel. 一种在通信信道上反射回来的信号。
- The caretaker stokes up twice a day. 管理员每天往火里加两次煤。
- A transparent body of this form, often of glass and usually with triangular ends, used for separating white light passed through it into a spectrum or for reflecting beams of light. 棱镜这种形状的透明体，多为玻璃制成，通常两端为三角形，用来分解穿过柱体的白光，使光束发生色散或用来反射光线
- I reflected on this proposal for some time. 这项建议我仔细想了一些时候。
- The beam of the searchlight pierced the darkness. 探照灯的光柱射入黑暗中。
- I go to the university twice daily. 我每天去那所大学两次。
