%X By using the elastic approximation model and scattering matrix method,we investigated the acoustic phonons transport and thermal conductance in a H-branch four-channel nanostructure. The calculated results show that,for the incident acoustic phonons of low frequency,as long as the transverse width of each channel is equal,the transmission coefficient of mode 0 in each channel almost equals 0. 25 and receives no influence from the changes of the other structure parameters. But for the incident acoustic phono...
