查询词典 hereditarily indecomposable continuum

Through the Laplace and Z transformations, it represents the varying features of electromechanical disturbance in a uniform chain network using the family of Bessel functions; the growing or attenuating laws are the same as that of electromechanical wave in a continuum model along the corresponding transmission media. Furthermore, the time of electromechanical disturbance arriving at any bus in the discrete model is also the same as that of electromechanical wave arriving at the corresponding bus in the continuum model.
