| 摘 要： | The discovery of the induced magnetic field of Callisto that is a satellite of Jupiter has been interpreted as evidence for a subsurface salty liquid-water ocean,so we consider a layered structure of callisto,i.e.,a rock-metal core,an outer layer of ice and a middle layer of ocean.For the rock-metal core we try to indicate how the temperature,pressure and mass density depend on the depth.Due to motionn across the magnetic field of Jupiter in a plasma environment,the ice shell of Callisto must be broken down by electric current.
