| 1. | This is equivalent to an angular distribution of constituent plane waves .
这等价于各种成分的平面波的角分布。 |
| 2. | If the wavefronts are parellel lines, the waves are called plane waves .
假如波前为一些互相平行的轮廓面，这波就叫平面波。 |
| 3. | Keep in mind that an idealized monochromatic plane wave must be depicted as an infinite wave train .
要记住，一个理想的单色平面波应当表述为一个无限的波列。 |
| 4. | The born approximation assumes that the incident and the outgoing particle can be described by plane waves .
玻恩近似假定入射粒子和发射粒子都可以用平面波来描述。 |
| 5. | It is important to recall that a sound wave in a nonhomogeneously deformed material cannot be a plane wave .
重要的是要记得，非均匀变形材料中的声波不可能是平面波。 |
| 6. | When an inhomogeneous plane wave is introduced into a dense dielectric layer, it can bounce between the two boundaries .
把一非均匀平面波引进折射率较高的介质层时，它会在上下界面间来回地“弹”射。 |
| 7. | Therefore, these equations with vanishing body forces cannot admit plane wave solutions under an arbitrary initial state of stress .
因此，这些方程当彻体力为零时，在任意的初始胁强状态下并不具备平面波解。 |
| 8. | A special type of unsteady motions which bear a resemblance to plane wave solutions of the linear theory of elasticity can be constructed .
一种特殊类型的、和线性弹性理论中的平面波解有点相象的非稳态运动可以建立起来。 |
| 9. | Admittedly, it is not at all obvious that by now shining a plane wave through the processed hologram one could reconstruct an image of the original object .
当然，我们还根本看不出，用一个平面波照射处理后的全息图，为什么能再现原来物体的一个象。 |
