| 1. | Those rays which are near the axis are sometimes called paraxial rays .
靠近轴的那些光线有时叫作近轴光线。 |
| 2. | The preceding chapter, for the most part, dealt with paraxial theory as applied to thin spherical lens systems .
前一章讨论的基本上是应用于薄球面透镜系统的傍轴理论。 |

| 4. | Then the influence of the spectrum property on the non - paraxial property of the pulsed beam is discussed
并对脉冲频谱特性对其非傍轴特性的影响进行了讨论。 |
| 5. | When the beam is thin enough that the width can be compared with the wavelength , we must consider the vectorial and non - paraxial effects
因此，当光束十分细小时(如等于或小于波长时) ，需要使用修正的公式。 |
| 6. | In chapter 2 , we discuss the optics self - focusing in beam propagation . the early research was based on the scalar approximation and paraxial approximation
早期的自聚焦研究是在考虑了傍轴近似和标量场近似的前提下得到的。 |
| 7. | Based on the theory of primary aberration , the first - order optical parameters are determined at first through its paraxial analysis , flat - field condition , and aberration characteristics

| 10. | The conclusion is that the vectorial effect influences more on the small - scale self - focusing than the non - paraxial effect . a new growing mode existing when the modulation on the direction of polarization is discussed in this chapter
同时与极化方向平行的新的增益模式有可能出现并可以在波长的尺度上产生自聚焦，文章讨论了这种可能性。 |
