金与碘相比，有着更高的原子序数和X射线吸收系数。
Compared with iodine, Gold has a larger atomic number and X-ray absorption coefficient.
文中分别得出了透射线及多次衍射线功率的表达式以及有效线吸收系数。
Separate expressions for the transmitted, and multiply diffracted power are obtained, which enable the effective absorption coefficient to be calculated.
这些样品本身对X射线的吸收系数及掺杂浓度不一样，因此它们的光发射效率也有所差别。
In addition, the absorption coefficients and the dopant concentration doped of these samples weren't the same for X-ray excitation, therefore, their light emission efficiencies were also different.
