有效原子序数

For the request of the high resolution ability of X-ray imaging, the inorganic scintillating materials with high effective atomic numbers and high density are studied intensely.

针对X射线高分辨成像的要求，具有较高有效原子序数和较大密度的无机闪烁材料成为当今研究的热点，重点阐述了溶胶－凝胶法制备这类闪烁薄膜的研究现状，并对其今后的发展进行了展望。

R is a reference referring to effective atomic number directly.

R是与有效原子序数直接相关的量。
