英语翻译The narrower the input beam,the higher the critical angl

The narrower the input beam,the higher the critical angle and the smaller the deviation of q0 from 。
输入光束越窄,那么临界角就越高,且对q0的偏差就越小。
The guided-wave amplitude is always smaller than that for the soliton beam in a uniform medium and approaches as guiding parameter p !0。
在相同的介质中,导波的振幅总是小于孤波光束的。且导波干涉成导向性的p !0参数。
Numerical simulations indicate that beams moving along the grating slowly radiate—an effect not captured by the effective-particle approach。
数值模拟表明向光栅缓缓移动的波束会发生辐射------一种不受有效粒子接近俘获的效应。
When solitons cross the waveguide,they lose a fraction of their energy because the wing of the soliton spatial spectrum overlaps the spatial spectrum of the guided mode。当孤波经过导波器时,它们会损失一小部分的能量,这是因为孤波翼侧的空间波谱与导波的空间波谱重叠。
The radiation rate increases as the incident angle approaches angleαb corresponding to the edge of the first Brillouin zone。12,13
随着入射角往 ab角靠近的时候,辐射速率是增加的,这与第一个布里渊散射区12。13是相适应的
The energy losses caused by the excitation of consecutive waveguides result in the slant soliton beam being trapped in one of the grating channels。
受连续性导波的激发而损失的能量会造成偏斜的孤波波束会被其中的一个光栅通道俘获。
This situation is shown in Fig。1(c)。Note that the propagation distance at which trapping occurs is relatively small。
这种情形在图1(c)可以得到说明：在俘获发生处的距离增殖是相对较小的。
Intuitively,it is clear that the larger the incident angle,the higher the channel number at which trapping occurs。
通过我们的直觉,很明显,入射角越大,在俘获发生处的通道数量会越高。
Such radiative trapping has much in common with the properties of discrete solitons in waveguide arrays;
在导波阵列中,这种辐射俘获与分离的孤波的性能有很多共同之处。
