我们提出了一个例子，一般禁止在一维相变在有限的温度应力诱导和热辅助粗糙化的超攀位错的Peierls潜力。我们还认为，这种粗糙化是在最近由Ray和Hallock [Phys. Rev. Lett. 105，145301（2010）]。
We present an example of a generically forbidden phase transition in 1D at finite temperature-stress induced and thermally assisted roughening of a superclimbing dislocation in a Peierls potential. We also argue that such roughening is behind the strong suppression of the superflow through solid (4)He in a narrow temperature range recently observed by Ray and Hallock [Phys. Rev. Lett. 105, 145301 (2010)].
