Abstract To clarify the effect of Hindered amine light stabilizer (HALS) on ultraviolet (UV) aging behavior asphalt binder, evolution history and characteristics UV induced micro-structure modified were characterized. Scanning Electron Microscope (SEM) Atomic Force (AFM) used to analyze microscopic morphology stabilizer-modified during aging. By defining in joints by UV, identification classifi...

Lacustrine mudrocks are composed of minerals and organic matter (OM). The origin preservation OM two controlling factors the hydrocarbon generation capacity mudrocks. It is a key method in source rock research to study deposition process from view sedimentary environment. Following this idea, reason for discrepancy production between northern southern part Dongpu Sag analyzed discussed. lacustr...

The Micro pump is an essential component in a Micro Total Analysis System (μTAS). A feasible and reliable design of the micro pump is a key for the development of the μTAS. The Valve-less Rectification Micro Pump (VRMP) has many advantages, such as: non-moving parts, independent of fluids and channels properties, reliable, and easy to fabricate. Fluid diodicity is an essential parameter of the ...

In this article we mainly aim to know what kind of asymptotic behavior typical orbits can display. For example, show in any transitive system, the empirical measures a orbit cover all dense and intersect some physical-like measures. particular, if union set is not singleton, then will display historic simultaneously for continuous functions limit ergodic average along every function equals clos...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...

Community public space is an important place for daily communication between residents. In the context of current historical change “urban double repairs”, community renewal has raised new heights, and shifted from surface physical transformation layer to protection, inheritance environmental quality community. This article summarizes concept principles micro-renewal, analyzes related influenci...
