摘要：
Measurements on the lattice thermal conductivity of Na in the liquid He-4 temperature range indicate that the phonon mean free path is independent of the phonon frequency and hence the temperature. The measured mean free path of 1.7-mu-m is believed to represent the scale of the martensitic transformation that occurs in Na below about 36 K.
