初版与再版邮票的质子激发X荧光鉴别法

报道用质子激发X荧光（PIXE）法分析我国初版与再版纪念邮票和特种邮票的实验结果。实验表明，初版和再版邮票所用印刷油墨颜料的化学元素的成分是不同的，因而PIXE方法可以用来实现初版和再版珍贵邮票的无损鉴定。这一方法也可以应用到对某些重要纸质文献或艺术品真伪的鉴定。

The identification of the republication and first publishing postage stamps by PIXE

The experimental results of the identification of some republiscation and first publishing postage stamps were reported by proton induced X-ray emission method (PIXE). The mea sured PIXE spectra showed that the chemical element composition and their relative concerntration were different each other, resulting from the different pinting inks used although their colours appear to be same. The experimental results show PIXE technique can be used to distinguish precious first publishing postage stamps from the republication or fakes non-destructively. This method also can be applied to distinguish the important document and precious paper arts from the fakes.
