【Abstract】 This paper discusses some class simulative microbe bottom interaction of BOD DO SDE which derive from optimal control system in active sludge theory, it is often used in city sludge transaction mill. By the property of ITO SDE and singular perturbation theory, we export the asymptotic expansion formula of solution of SDE.更多还原
