... agreement between experiment and theory implies that the process is
understood . The generalization of the flux Eq . ( 15 ) to the so - called
phenomenological theory of diffusion is possible by treating the system as a
thermodynamic one .

A better representation of Eq . ( 48 ) is possible by denoting Q ( j ) = w2 / ( w2 +
4w , + 7w3 ) [ 1 , 1 , 1 , 1 , 00000 , . . . ) . Hence Q ( j ) is the probability of the
vacancy making a tracer exchange from site j ; Q ( j ) is written as a row vector .

... D = } b rCf = Rf The remainder of the calculation is the determination of the
column vector f from Eq . ( 64 ) . Since the symmetry elements reduced the 19
possible jump types to 13 as given in Table I , there are 13 elements in the vector
f .
