• The bubble raft is set in a vibrating state in order to approximate the real crystal in thermal vibratjon more precisely by the model. The exciting vibration of 90 c/sec is transmitted to the bubble raft through the sustaining liquid. In the vibrating state, it is observed that the bubble raft expands uniformly until a critical state is reached, where the regular alignment is destroyed abruptly. By means of the lattice expansion, a formula is proposed defining a reduced temperature of the bubble raft corresponding to each input power of vibration. The diffuseness of the irregularity characteristic of the lattice imperfections, such as the vacancy, the vacancy group, the interstitial and the dislocation, is observed to increase in general under vibration. In the case of the vacancy group, it can be detected the stacking faults characteristic, to the bubble raft. Some preliminary discussions are attached as to the cause of the raft expansion and of the diffused lattice imperfections, the characteristics of the disordered state at the critical point, and the geometrical mechanism of formation of the stacking faults by means of the imperfect dislocations.
