查询词典 incidence angle

Pn 2.3.3 Standing Waves or Resonances When a free progressive wave encounters a sharp change in impedance such as at an air-hardwall boundary, and if the angle of incidence is normal, then the reflected wave travels back along the original path of propagation with a 360 ° change in phase.

pn 2.3.3 驻波和共振当自由行波遇到波阻突变时，比如遇到气壁边界，若入射角度垂直于边界，那么反射波会沿原路径返回，相位变化360°。

At each point on the surface, the laws of refection are obeyed, but the angle of incidence varies from one point to another.

The result is that center frequency shifts to low-frequency with increase of incident angle under oblique incidence, the band width narrows correspondingly, for both square element arrangement and regular triangle arrangement.

结果发现，无论单元是按正方形布阵还是按正三角形布阵，在电磁波斜入射时中心频率都随入射角的增大而向低频漂移，带宽都相应减小。

So when the wavelength of the incident light changes, only the position of rhomb-type retarder need to be changed to allow the light to represent oblique incidence in the front of rhomb, and then selecting suitable incident angle can compensate the dispersion phase deviation, and make the same rhomb possess standard λ/4 phase retarder under all different wavelengths.

当入射光的波长改变时，只需改变菱体延迟器的方位，让光线在菱体的前端面上斜入射，适当选取入射角，就可以补偿相位延迟的色散偏差，使同一菱体达到对不同波长都满足λ/4相位延迟。

The numerical results show that a reasonable reconstruction is also possible for low wavenumbers even when the incidence and observation aperture is as small as the possible π/4 solid angle.

数值结果表明，对较小的波数，即使当入射和观测孔径为π/4立体角时，得到一个合理的重构也是可能的。

With oblique incidence transversal wave, defect mode of transversal wave decreases with increase of incident angle.

得到当横波斜入射时，透射波中横波的缺陷模随着入射角的增大而减弱，横波向纵波的转型随着入射角的增大而增强。

It has been suggested that the architecture of the lower lumbar vertebrae and sacrum (e.g., inadequate separation between the inferior articular process of L4 and the superior articular process of L5, a wedged-shape interfacet region of L4, a more frontally oriented lumbar facet, and a wider sacrum), pelvic orientation and lumbosacral parameters (e.g., pelvic incidence, sacral table angle) may play a role in the development of spondylolysis.

低位椎体和骶骨的结构（如L4下关节突与L5上关节突间隔不足，L4下关节突成楔形，腰椎小关节方向过分偏额面方向，骶骨过宽），骨盆方向和腰骶段的参数（如骨盆影响和骶骨水平角）可能在脊柱滑脱的发展中扮演重要角色。

This paper analyzed the reflection spectrum of loess on different granule diameters and irradiant angles. We found that the influence of loessial dense degree on its polarized reflection changed along with loess's moisture content and angle of incidence.

本文以黄土作为代表性土壤，通过对不同粒径，不同光线入射角黄土反射光谱的分析，我们发现黄土的致密程度对其偏振反射光谱的影响与黄土自身的含水量以及入射角相关。

All of the patients were divided into three groups,autologous bone graft in 21 cases,allogous bone graft in 23 cases, autologous bone mixed allogous bone graft in 27 cases. The fusion rate, the Cobb's angle loss rate of incidence and pseudoarthrosis were compared among the three groups at 3,9,15,36 months follow-up.
