摘要
Transport coefficients are often expressed in the form of an Einstein relationship. In this report we point out some possibly surprising properties of the correlation functions appearing in such expressions and we discuss under what conditions the relationships are true. We further consider the Einstein relationship for the shear viscosity proposed by McQuarrie [in Statistical Mechanics (Harper and Row), 1976]. On the basis both of theoretical analysis and computer simulation, we conclude that this expression is incorrect.
