By using Green's functional method, we investigated the influence of different strength constants at defected bonds and the junction's size on the transmission properties of the lattice wave in a one-dimensional chain. The heat currents of several defected chains are also calculated. The results show that correlation transmission between two defected bonds in a chain different from electron behaviors. Furthermore, for a large-size junction embedded in a chain, the transmission of high frequency phonons will disappear while having smaller strength constant in the junction than in two semi-infinity chains. On the other hand, for larger strength constant than in two semi-infinite chains, all phonons can transport through the junction with a certain transmission value, although the number of transmission peaks decreases. Finally, the lower frequency lattice waves have better transmission through a junction with a series of strength constants according to the Fibonacci sequence.
