Abstract:To optimize operational parameters of fluidized-bed lignite gasification technology.
It is well accepted that amorphous or glassy phase is formed when coal was heated, which can’t be reflected by an XRD pattern, but the chemical composition in each material can be estimated by portioning techniques from XRD and bulk chemical analysis data [9].

Abstract.
The name and inspiration come from annealing in metallurgy, a technique involving heating and controlled cooling of a material to increase the size of its crystals and reduce their defects.
In this sense, steganalysis is actually a matter of pattern classification in which a key issue is how to select effective features.

Introduction:Graphene, a two-dimensional honeycomb lattice of sp2 bonded carbon atoms, has attracted worldwide interest due to its excellent transport properties that make it a promising material for next-generation nanoelectronics[1-4].
The low nucleation density of graphene on Cu foils is the key for SCG growth.
