“Strange–Rahman–Smith equation”的意思、由来-开放百科全书

The Strange–Rahman–Smith equation is used in the cryoporometry method of measuring porosity.

NMR cryoporometry ^[1]^[2]^[3] is a recent technique for measuring total porosity and pore size distributions. NMRC is based on two equations: the Gibbs–Thomson equation, which maps the melting point depression to pore size, and the Strange–Rahman–Smith equation, ^[1] which maps the melted signal amplitude at a particular temperature to pore volume.

Equation

If the pores of the porous material are filled with a liquid, then the incremental volume of the pores

with pore diameter between

and

may be obtained from the increase in melted liquid volume for an increase of temperature between

and
