diffusion damping造句
例句與造句
- Diffusion damping thus damps temperature and density anisotropies in the early universe.
- This reduction in anisotropy is the " damping " of diffusion damping.
- Scientists say diffusion damping affects " small " angles and corresponding anisotropies.
- The effect of diffusion damping is greatly augmented by the finite width of the surface of last scattering ( SLS ).
- What affect the diffusion length are primarily the properties of the plasma in question : different sorts of plasma may experience different sorts of diffusion damping.
- It's difficult to find diffusion damping in a sentence. 用diffusion damping造句挺難的
- The structure of the cosmic microwave background anisotropies is principally determined by two effects : acoustic oscillations and diffusion damping ( also called collisionless damping or Silk damping ).
- The scale on which diffusion damping works is called the "'Silk scale "'and its value corresponds to the size of galaxies of the present day.
- In diffusion damping, photons from hot regions diffuse to cold regions by random walk, so after \ mathit { N } steps, the photons have travelled a distance \ lambda _ D = \ sqrt { \ mathit { N } } \ lambda _ C.
- Though general diffusion damping can damp perturbations in collisionless dark matter simply due to photon dispersion, the term " Silk damping " applies only to damping of adiabatic models of baryonic matter, which is coupled to the diffusing photons, not dark matter, and diffuses with them.
- The strength of diffusion damping is calculated by a mathematical expression for the " damping factor ", which figures into the Boltzmann equation, an equation which describes the amplitude of perturbations in the CMB . The strength of the diffusion damping is chiefly governed by the distance photons travel before being scattered ( diffusion length ).
