METHOD OF ANALYZING SHEET PRODUCT, SHEET PRODUCT MANUFACTURING METHOD USING THE FORMER METHOD, AND SHEET ARTICLE MANUFACTUREING APPARATUS

摘要

At least two elements contained in a sheet product (22) are determined by irradiating the sheet product (22) with a plurality of beams of X-rays of different wavelengths and by measuring the intensities of the X-rays transmitted through the sheet product (22). By this method, at least two elements in the sheet product containing two or more elements can be determined.
