摘　　要：　　Buried nano-structures,such as interface and precipitate,are traditional interests of microscopists and spectroscopists.However,imaging is limited to 2D and often restricted to uniformity through the thickness.AEM analysis Can get partially quantitative information for the buried structures but it complicates with the probe characteristics.An indirect EELS methodology,"spectrum separation"developed based on"spatial difference"technique,is suitable to explore the full chemical information of the buried nanostructures,benefiting from the inherent connection of structure and composition ofany phase from the atomic scale on.……
