例句 释义: 全部,散射平均自由程 更多例句筛选 1. The average distance a photon travels before it is scattered is called the 'scattering mean free path '. 一个光子在被散射前所传播的平均距离称为“散射平均自由路径”。 dictsearch.appspot.com©...
albedo始终介于0和1之间;它描述了散射事件中发生散射的概率(相对于吸收)。 第二个值是mean free path,1/σt,它给出光线在介质中传播在与粒子发生相互作用之前行进的平均距离。 给定衰减系数σt,描述整体衰减的微分方程如下 \frac{dL_o(p,\omega)}{dt}=-\sigma_t(p,\omega)+L_i(p,-\omega) 可以求解...
在物理上,d 和介质的平均自由程(mean free path) \ell ,即光线在介质内两次连续散射之间传播的平均距离有关,可取值 d = \frac{\ell}{s},其中 s 是标度因子(scaling factor),取决于A; 当光线垂直入射表面时,标度因子可取值 s = 1.85 - A + 7 \left|A-0.8\right|^3; 对于漫反射折射的表面,标度...
In this calculation, viscous damping effects are included, which results in broadening of the resonance function. It is demonstrated that including resonance function broadening ensures a finite mean free path for cosmic ray energies, for which previously reported types of turbulence predicted an ...

Figure 9. The mean free paths in SiO2 as a function of the electron energy for scattering at optical phonons (LO) and acoustic phonons (ac) and for impact ionization (ii), together with the attenuation length (at) for monoenergetic electrons.(Reprinted with permission from Schreiber and Fittin...
(diameter of 1 μm) in PDMS, and its scattering mean free path was determined by measuring the intensity of ballistic photons as a function of the thickness of the layer (Supplementary note3). The typical scattering mean free path of the samples used in the experiment wasls = 102 ...
(Rg). The root mean squared distance calculated from the centre of contrast (typically the centre of mass). Probable frequency of real-space distances p(r) (Otherwise known as pair-distance distribution function). The inverse Fourier transform of the form factor that converts the reciprocal spac...
The method is suitable for cylindrical scatterers with dimensions up to the mean free path of the neutrons. An alternative correction method via an adjusted neutron attenuation correction is discussed.关键词: nuclear reactions and scattering due to neutrons/ A2540 Nucleon-induced reactions and ...
