英文摘要	Using the transfer matrix renormalization group (tmrg) method, we study the connection between the first derivative of the thermal average of driving-term hamiltonian (dtadh) and the trace of quantum critical behaviors at finite temperatures. connecting with the exact diagonalization method, we give the phase diagrams and analyze the properties of each phase for both the ferromagnetic and anti-ferromagnetic frustrated j(3) anisotropy diamond chain models. the finite-temperature scaling behaviors near the critical regions are also investigated. further, we show the critical behaviors driven by external magnetic field, analyze the formation of the 1/3 magnetic plateau and the influence of different interactions on those critical points for both the ferrimagnetic and anti-ferromagnetic distorted diamond chains.
