Temperature Independent Renormalization of Finite Temperature Field Theory [PDF]

open access: yesAnnales Henri Poincaré, 2000
We analyse 4-dimensional massive $\vp^4$ theory at finite temperature T in the imaginary-time formalism. We present a rigorous proof that this quantum field theory is renormalizable, to all orders of the loop expansion. Our main point is to show that the

Generator flow field and temperature field analysis [PDF]

open access: yesMATEC Web of Conferences, 2018
In this paper, the flow area of the generator and the solid area of the generator are taken as the research object. According to the theory of fluid mechanics and heat transfer, the CFD software Fluent is selected as the calculation tool, and the direct ...

Medley in finite temperature field theory [PDF]

open access: yesCanadian Journal of Physics, 1993
I discuss three subjects in thermal field theory: why in \sun gauge theories the \zn symmetry is broken at high (instead of low) temperature, the possible singularity structure of gauge variant propagators, and the problem of how to compute the viscosity

Research on Aerodynamic Performance of High-Pressure Capturing Wing with Bi-Wing Configuration in Wide-Speed Range

open access: yes气体物理, 2023
The aerodynamic configuration design of wide-range hypersonic vehicle has become one of the research hotspots. The new aerodynamic configuration of high-pressure capturing wing (HCW) can meet the requirements of high volume ra-tio, high lift and high ...

Identification of secondary fatty alcohols in atmospheric aerosols in temperate forests [PDF]

open access: yesBiogeosciences, 2019
Fatty alcohols (FAs) are major components of surface lipids (waxes) and can act as surface-active organic aerosols in the atmosphere, influencing chemical reactions, particle lifetimes, and the formation of cloud droplets and ice nuclei. However, studies

Early snowmelt by an extreme warming event affects understory more than overstory trees in Japanese temperate forests

open access: yesEcosphere, 2022
The occurrence of extreme warm events and early snowmelt is predicted to increase in high‐latitude ecosystems, even during periods of time when there is no coincident reduction in total precipitation.

Effects of the glacial meltwater supply on carbonate chemistry in Bowdoin Fjord, Northwestern Greenland

open access: yesFrontiers in Marine Science, 2022
To understand the effects of the glacial meltwater supply on carbonate chemistry and the air–sea CO2 flux within the fjord, water samples were collected in Bowdoin Fjord in northwestern Greenland for dissolved inorganic carbon (DIC) concentration, total ...

Thermodynamic Simulation Analysis of Variable Buoyancy Device for Underwater Gliders

open access: yes水下无人系统学报, 2022
The heat generated by its driving motor and pump affects the internal structure of the device when a variable-buoyancy device on an underwater glider is operating, thus posing risks to its normal operation.
