摘要：
We consider two Cauchy problems for the one-dimensional thermoelastic Bresse model. Using the energy method in the Fourier space, we show that for the first model, the L-2-norm of the solution decays with the rate (1 + t)(-1/12). In addition, the same decay rate has been obtained for the second model.
