Pore width是什么意思
WebSep 2, 2016 · Now, I want to calculate pore volume and average pore diameter. ... In the excel file, the cell B60 is BJH Adsorption average pore width (193.728A o). WebPore area is dynamically adjusted by changes in pore width, because pore length is rather rigid during opening and closure of stomata (Lawson et al., 1998). Maximum stomatal pore width can be approximated only under very low evaporative demand, low carbon dioxide concentration and high light intensity (Drake et al., 2013; Dow et al., 2014a).

Webpore widths (array) -- The widths of the pores. pore_dist (array) -- The distributions for each width. pore_vol_cum (array) -- Cumulative pore volume. Notes. Description. The H-K method [5] attempts to describe adsorption within pores by calculation of the average potential energy for a pore and equating it to the change in free energy upon ... Web)O systems, the pore size distributions of the HTlcs were narrower and the pore diameters were smaller. The BJH pore diameters and pore volumes confirmed that O was an Cu(Fe) non-porous material, which explained its low surface area. The BJH pore diameters and pore volumes also illustrated that most of the prepared MO were non-porous materials.
