A 3D T chaotic system with absolute terms is constructed.The bifurcation diagram,Lyapunov exponent，0-1 test and phase diagram of Matlab analyzing system are used to verify the sensitivity of the new chaotic system to system parameters.To further study the influence of the double parameter change on the system,dynamics analysis of the system through space bifurcation diagram is carried out,which reveals the chaotic characteristics and realizability of the system.
