摘要：

The constitutive laws are obtained for the linear micropolar thermopiezoelectric/piezomagnetic continuum with two relaxation times. A positive decreasing dissipative pyroelectric/pyromagnetic function is introduced and a uniqueness theorem is proved. The equation of motions and the boundary condition are obtained from a Hamilton's type variational principle. Extended Hamilton's principle is given.
