您要查找的是不是：
- x ray refractive index x 射线反射率,x射线折射指数
- The function n(x, y)is known as the refractive index profile. 函数n（x，y）称为折射率分布。
- Ray refractive index 射线折射率
- When will I know the result of my x ray? 我何时可以知道X光检查的结果?
- The refractive index n(X) varies gradually over the cross-section of the guide. 折射率n（x）在波导截面内是逐渐变化的。
- X ray is increasingly used in industry as well. 在工业中X射线也得到了广泛应用。
- The x ray show a fractured ankle. X 光片显示足踝骨折。
- You shall have an x ray examination. 你应该作X光检查。
- Shall I use X ray to have a check? 是不是用X光透视一下?
- The dentist showed me the X ray of my teeth. 牙科医生把我牙齿的X光片拿给我看。
- The refractive index of one kind of micro-structured fiber were studied by optical ray theory, the distribution of refractive index is gived. 应用射线理论对一种微结构光纤包层的折射率进行了计算，给出了折射率分布的精确解。
- Dr Hess envisages a ray of light travelling down an optical fibre made from two materials: a core with a negative refractive index and an outer sheath with a positive one. 赫斯博士构想出一个画面，即一道光正穿越于一个由两种材料制作的光导纤维，一种是具有阴性折射指数的纤维核，另一种则是具有阳性折射指数的外围。
- The doctor took an X ray photograph of the chest of his patient. 医生给病人的胸部拍了一张X光片。
- Optical glass of low dispersion and low refractive index. 低色散、低折射率光学玻璃。
- The hospital will arrange an X ray examination next week. 医院将在下周安排一次X光检查。
- The refractive index also increases with the RTA temperature. 薄膜的折射率随退火温度的升高而增加。
- An X ray of of a joint after the injection of a contrast medium. 填充上照影剂后用X射线照关节。
- Chest X ray realed infiltration in low lobes of lungs. 胸部X线 4 5例 (83.;7%25 )表现下肺斑片、片絮状阴影或肺纹理粗乱。
- LDRD images quality is better than routine X ray photographs. 运用LDRD系统实现胸部X线摄影 ,照片的整体质量明显高于传统胸片的影像质量
- Each structure has its own refractive index, and when a light ray crosses an area where the index changes, the light scatters, creating a degree of opaqueness. 每个构造都有各自的折射率，当光线穿越折射率不同的区域时，便会散射而造成某种程度的不透明。
