The phrase "amount of diffusion" is correct and usable in written English.
It can be used in scientific or technical contexts when discussing the extent or quantity of diffusion occurring in a particular situation or experiment.
Example: "The amount of diffusion observed in the experiment was significantly higher than anticipated, indicating a more rapid movement of particles."
Alternatives: "degree of diffusion" or "extent of diffusion".
The phase field model replaces the sharp discontinuities with a scalar damage field representing the diffuse crack topology through controlling the amount of diffusion by a regularization parameter.
Mean diffusivity (MD) is a measure of the total amount of diffusion within a voxel and is computed as an average of all three diffusion axes [ 47].
Two measurement sets are used to study the effect of ignition delay and amount of diffusion combustion on cyclic variations.
The NR results indicated that even at these high molecular weights a certain amount of diffusion did occur but was confined to the first few hundred Angstroms of the interface.
A small amount of diffusion is added to the models to indicate a small difference between the anticipated and the real-life realizations of the event.
where △ represents the graph Laplacian of the network, α > 0 is a real number that scales the amount of diffusion across the nodes, and σ d ω is white noise with scale σ.
In cases with high amounts of diffusion combustion, the effect of fluctuations on average NO emissions correlated with increasing ignition delay.
Combining images obtained with different amounts of diffusion weighting provides an apparent diffusion coefficient (ADC) map.
It is concluded that diffusion is an important transport mechanism in cross-ventilation of buildings, and that special care is needed to select the right amount of physical diffusion and to reduce the numerical diffusion, using high-resolution grids and using at least second-order accurate discretisation schemes.
N UTRIENT diffusion used a discretization of the two-dimensional continuous diffusion equation du/dt = D∇ u, where D is the diffusion constant and u is the amount of diffusible material.
Computed diffusion tensor eigenvectors represent the voxel-specific orthogonal principal axes of diffusion, in which each respective eigenvalue reflects the amount of diffusivity in these axes [ 10].
