By virtue of the static mixer, the degree of mixing ammonia gas with smoke can be remarkably improved, the uniformity of ammonia-nitrogen molar ratio is improved, small system damage is generated, and the short-distance mixing is achieved; meanwhile, the static mixer has the characteristics of ...
larger than the force of kinetic friction (in the limit as the sliding velocity approaches zero) for solid-on-solid sliding can be accounted for by considering the strain released during atomic level `stick-slip' motion that occurs during the sliding of two elastic bodies relative to each ...
Research has shown that the mechanical response of multi-layer beams also depends greatly on the shape of the interface between the layers.#Some main points in this work are concluded as follows: the natural frequency of the beams will drop if the values ofk0andV0are raised in either directi...

OBJECTIVE: To study the frictional characteristics of LF bracket when it is sliding along an archwire compared with regular four wings bracket in dry and wet state. METHODS: The surface states of the stainless steel rectangular archwires were observed with scanning electronic microscope in order to...
Theoretical modelling predicts very unusual structures and properties of materials at extreme pressure and temperature conditions1,2. Hitherto, their synthesis and investigation above 200 gigapascals have been hindered both by the technical complexity
Thermal Treatment of Stabilized Air Pollution Control Residues in a Waste Incinerator Pilot Plant. Part 2: Leaching Characteristics of Bottom Ashes With the perspective of generating only one solid residue from waste incineration, co-feeding of municipal solid waste and air pollution control residues s...
