title: A discussion about the DiFrancesco-Noble model.
abstract: An obvious defect in the DiFrancesco-Noble (DN) model was found, so methods to overcome this inadequacy are put forward. Based on these methods, different kinds of modified DN model can be obtained, and numerical results show that most of the dynamics of the DN model can be essentially preserved by these modified systems.
