In this paper we present clearly a set of postulates on probabilities which are the basis of the nonlinear master equations and multivariate linear master equations appeared in non-equilibibrium statistical physics. By using the methods of probability theory, we deduced these master equations from our general postulates. We further discussed the conditions under which the master equations are consistent with the macroscopic kinetic equations.

By using the methods of probability theory, we deduced these master equations from our general postulates. We further discussed the conditions under which the master equations are consistent with the macroscopic kinetic equations. Finally, we discussed the fluctuation in Brusselator model using multivariate linear master equation approach and made a preliminary explanation on the appearance of dissipative structure through fluctuation.

This paper deals with the macrokinetics of water gas shift reaction on commercial iron oxide catalysts. In an internal recycle gradientless reactor, type B106 and B109 shift catalysts of commercial size and cylindrical in shape, have been studied under atmospheric pressure. Reaction conditions were: temperature 350° to 480℃, molar ratio of steam to carbon monoxide 2 to 11, dry gas space velocity 150 to 1500ml/(h. g). Experimental results showed that the macrokinetic equations for both catalysts can be expressed by the common formula:
