Slope Ground Mass is a naturally damage the material, due to inability to accurately obtain the elastic modulus when the lossless, so the slope body forming state as the reference damage state, the surface water infiltration of slope as the n-damage state.
Equivalent strain hypothesis according to Lemaitre after injury expression derived benchmark status: D=1-E′/E Wherein, E is the intact material elastic modulus, E' is the elastic modulus of the damaged materials.

Crystallite size and strain study of a nanostructured Fe-Cu alloy from
diffraction profile analysis
O.
X-ray diffraction peak profile analysis is a powerful tool for the characterization of microstructures in crystalline materials.
Diffraction peaks broaden when crystallites are small or the material contains lattice defects.
The blend was loaded under Ar atmosphere into stainless steel vials previously coated with the material to be ground.

Indeed, simulation can be applied to analyze how manufacturing systems performance is influenced by different factors such as layout structure, number of resources are used in material handling, resource functioning policies and usage of various kinds of material handling systems.
For production of industrial paints at first, raw material is moved from the inventory part and resin is added to the calderon and then carried to the mixer by jack pallets.
If the product does not meet the standards it is mixed again and other necessary material are added to the paint.

LGD Process
FGD system includes the raw material conveying system, the preparation system of absorbent slurry, the flue gas system, the SO2 absorption system, gypsum dewatering and storage, and recovery gypsum system.
The nozzle made of wear-resisting SiC material can spray the slurry with fine droplets covering the entire interface of stream through and the nozzle service life is long [4].
Generally, in the stage of raw material preparation, particle size of the limestone must be strictly controlled, which the ≤325 meshes particle is above 90%.
However, anticorrosion measures should be considered in design, such as alloy material for manufacturing equipment and pipeline, using lining, reinforcing thermosetting resin using glass fiber, and designing a bypass of heat regulation [5].
