where [tau] is the relaxation time
, [omega] is the angular frequency, and H (r) is the relaxation time
The measured parameters compared between the two groups included T1, T2, T2* relaxation times
, fat fraction (FF), and cross-sectional area (CSA) of the quadriceps femoris and the hamstring muscles.
At the new structure, we set the Fermi energy of graphene [E.sub.F] = 0.8 eV and the relaxation time
of graphene [tau] = 1.5 ps; the constants of dielectric slab 1 and dielectric slab 2 are set as 11.9 and 3.84, respectively.
It is evident from Figure 7 that relaxation time
increases with increase in concentration of polyvinyl alcohol in solution.
Figures 1(c) and 1(d) show that, under different storage conditions, the extension of storage time for all fresh wet noodles gradually decreased the relaxation time
[T.sub.22] of the intermediate state water, and the water transformed from the combinative state to the intermediate state, for an overall decrease of total water content.
Here we will use the normalized time t by introducing the dimensionless time [??] = t/(L[square root of ([rho]/3[mu]))], [??] = c/(2[mu][L.sub.3]L[square root of ([rho]/3[mu])) and dimensionless relaxation time
[??] = ([eta]/[[mu].sup.B])/(L[square root of ([rho]/3[mu])), and we may reduce (12) and (13) to the following form:
The amounts of proton nuclei, T1/ T2 relaxation times
and the kinetics of molecules of water, are the most important parameters.18,20 The contrast of an MR image depends simultaneously on several considerations, e.g.

The [T.sub.2] relaxation time
was obtained using MESE sequences (Seq.
The combined phonon relaxation time
r for impurity scattering and U scattering can be given by Matthiessen's formula, as in (5), and the possibility of boundary scattering is only dependent on its locations in the simulated physical model.
Relationship between the Capillary Pressure ([P.sub.C]) and the Nuclear Magnetic Transverse Relaxation Time
