The recent controversy over whether the photon diffusion coefficient depends on absorption is addressed by use of the analytical solution of the photon transport equation in an infinite homogeneous scattering medium. The diffusion coefficient is found to be independent of absorption but temporally dependent...
In the formulation presented in this work, the diffusion coefficient depends on the mixing length when the mixing length is very small. In calculations with the method of Langer et al., the efficiency factor of the diffusion coefficient of chemical species is sometimes much smaller than 1. This...
水泥细度对混凝土氯离子扩散系数影响不大；6.This equation describes the diffusion coefficient depends on a quantity and its gradient in a diffusion procedure.这一方程描述了扩散过程中扩散系数依赖于未知量及其自身梯度。
so that diffusion-controlled reactions will occur at a lower rate inlipidmedia. The experimental determination of thediffusion coefficientdepends on•NO interaction with fluorescent orspin probesinserted in the membrane. The parameter readily available from these experiments is the apparent diffusion (D...

The threshold concentration depends on the length of the percolating cluster. Consequently, Eeff is also size dependent. So it is shown that the diffusion coefficient depends on the distance of diffusion. The determination of the effective activation energy from the slope of the Arrhenius plot of ...
In the case when\({D}_{1,\,{z}_{{i}_{1}}}\)is uncorrelated with\({z}_{{i}_{2}}\)and\({D}_{1,\,{z}_{{i}_{2}}}\)uncorrelated with\({z}_{{i}_{1}}\), then the growth of the variance only depends on the diffusion coefficient. ...
Error expressions derived from the commonly used equations of electroanalytical chemistry using Taylor''s series show how a calculated value of n, the number of electrons transferred, depends on the error in D, the diffusion coefficient. The error relationships for chronoamperometry, polarography, ...
However, the porosity test method can determine the diffusion coefficient based on the porous material microstructure. For the first time, this method was developed by Carniglia (1986) to obtain the effective diffusivity of gaseous species in oxidants and catalysts. And then, it was later employed...
We study independent stochastic processes , defined by a stochastic differential equation with diffusion coefficients depending nonlinearly on a random variables and (the random effects).The distributions of the random effects and depends on unknown parameters which are to be estimated from the continuous...
