查询词典 ray of light

When propagating light\|ray passes through two fixed points in the gradient index mediums and a cuspidal variable\|point （at this point the trace equation of propagating light\|ray is non\|differentiable） at the borderline of two different GRIN mediums, the mathematical relationship, which the trace equation of propagating light\|ray and borderline equation of two different GRIN mediums should satisfy, is derived by the Fermat's principle and calculus of variation.

The ray from the plasma lamp will go through into the light pipe with little incident angle after reflection by the reflector, and then the total reflection of the ray will occur among the prismatic reflecting films. Some ray may come to the end mirror and will be reflected back, and only a little of rays pass through the prismatic reflecting films, most of the rays will go forward by the action of the bottom light extracting surface and go out to be lighting.

等离子灯球发出的光线经过反射器反射后，以很小的入射角进入到导光管，光线在棱镜反光膜管子内进行全反射，到达丙烯酸树脂管端底镜面的光线，再反射回到管子内部，只有少量的光线透过棱镜反光膜出来，最终大部分光线通过管子底部的光线提取面引出管外，传送到所需要照明的宽广区域（见图7）。

Results In 7 cases of odontoid process fracture, X-ray demonstrated 4 cases and CT demonstrated 5 cases, whereas the spiral CT reconstruction diagnosed 7 cases, which could display the displacement of fracture clearly. The X-ray and CT showed asymmetric space between left and right gaps of atlantoaxial joint in 6 cases, while spiral CT reconstruction showed normal and excluded the possibility of atlantoaxial dislocation. There was one case of lateral atlantoaxial joint dislocation, which was demonstrated by the spiral CT reconstruction clearly but not by the X-ray and CT scan. There were 3 cases of atlantoaxial congenital deformity (1 case of absence of both posterior arch of atlas and odontoid process and 2 cases of maldevelopment of the odontoid process), which were displayed clearly by spiral CT reconstruction, but misdiagnosed as odontoid process fracture and atlantoaxial subluxation by X-ray and CT scan.
