Webb14 apr. 2024 · where W represents the amount of water absorbed, A is the area of the specimen exposed to water, and t is time. S 0 is used as a correction coefficient for the initial amount of water absorbed by the pores. Another more recent model by which to represent capillary water absorption is the one proposed by Villagrán et al. . WebbThe gain coefficient can be expressed as: o s o T P P g g 1 ( ) / ( ) 2 2 2 gois the peak gain, is the optical frequency of the incident signal, ois the transition frequency, P is the optical power of the incident signal, T2is the dipole relaxation time, and … compare the market characters
