diffusion distance造句

• Thus they present a large surface to volume ratio with a small diffusion distance.
• To decrease run times and increase selectivity, smaller diffusion distances have been pursued.
• To achieve smaller diffusion distances there has been a decrease in the particle sizes.
• Monoliths also have very short diffusion distances, while also providing multiple pathways for solute dispersion.
• This is achieved by depositing the electrodes away from the mirror, at least several carrier diffusion distances.
• The pore elimination occurs faster for a trial with many pores of uniform size and higher porosity where the boundary diffusion distance is smaller.
• The concept of diffusion arises from the definition of a family diffusion distance { D _ t } _ { t \ in N}
• Although its lifetime is fairly short ( about 50 microseconds ), superoxide has the potential to reach cell surfaces since it has a diffusion distance of about 320 nm.
• Fine lamellae solve this problem by shortening the diffusion distance between phases, but their high surface energy makes them unstable and prone to break up when annealing allows diffusion to progress.
• Immature chorionic villi are larger and have more central blood vessels; thus, the diffusion distance for gas and nutrient exchange is larger and, therefore, placental function is impaired.
• Fish must extract oxygen dissolved in water, not air, which has led to the evolution of gills and lamellae : the lamellae contain capillaries and provide a large surface area and short diffusion distance, as they are extremely thin.
• Important examples of such techniques include : classical multidimensional scaling, which is identical to PCA; Isomap, which uses geodesic distances in the data space; diffusion maps, which use diffusion distances in the data space; t-distributed stochastic neighbor embedding ( t-SNE ), which minimizes the divergence between distributions over pairs of points; and curvilinear component analysis.
