加州大学戴维斯分校的科学家们已测定哥登堡圣经印刷的纸张和墨水的成分。这是用活字印刷的第一本书,曾被一些专家认为是自有印刷术以来的最好的印刷版本。用粒子感应 X 射线发射进行分析。这里的2m同步回旋加速器产生的质子束在样品上能产生3.8MeV,产生一 X 射线被放大,然后用脉冲光学反馈检波器测量,以任意峰值探测技术为基础的光谱分析提供了基本的识别方法。 Scientists at the University of California, Davis, have determined the composition of the paper and ink printed on the Bible in Gothenburg. This is the first book printed in movable type and was considered by some experts as the best printed version since its own printing. Analysis with particle-induced x-ray emission. The proton beam generated by the 2-m synchrotron here produces 3.8 MeV on the sample, produces an X-ray that is amplified and then measured by a pulsed optical feedback detector, providing the basic method of spectroscopy based on arbitrary peak detection techniques .
