The intensity reflectivity of the film is correlated with the wavelength of an incident ray and the height of the film.
该空气薄膜的光强反射率是关于入射光波长和薄膜厚度的函数。
The results show that the factors are the refractive index thick ness layer number of one-dimensional dual photonic crystal polarization and incident angle of incident ray .
结果表明：组成一维二元光子晶体的折射率、厚度、层数、入射角、光源的偏振态等都对透射特性有影响。
As the film sample is fixed on one plane by tighten bolt, this device can realize the deflection of optical path. And the reflectivity of the sample is measured by using oblique incident ray.
使用该装置并通过平面和样品背后的顶丝固定薄膜样品的安装方式，可实现光路转折，完成斜入射光对薄膜样品反射率的测量。

In one incident widely reported in 2003 the imaging agent Celobar (something injected into the bloodstream to provide an X-ray contrast) was manufactured in a way that poisoned and killed at least a dozen patients in Brazil.
