用维纳滤波法复原闪光X光图片

In X-ray fluorescence, pieces of the filter are used directly.

在 X 射线荧光法中, 可直接使用滤纸.

The ROSS filter spectrometer for soft X ray spectrum measurements has been studied in this paper. The basic principle of the ROSS filter difference pair is introduced. Design and the calculation results of ROSS filter difference pair are given.

介绍了ROSS滤片差分法基本原理，给出了ROSS滤片差分对的理论设计及实际应用差分对的响应函数计算结果。

The relation between the filter transmissivity and density, thickness and x-ray wavelength is studied by the Lambert-Beer law, it will decrease when the x-ray wavelength increases, and it is lower especially for the longer wavelength.

根据朗伯&比尔定律，研究了滤光膜的透射率与其密度、厚度和X射线波长之间的关系，它随X射线波长增大而减小，尤其是对长波长X射线衰减得相当厉害。
