摘要: Abstract Previous studies on the influence of a heat current flow helium II in narrow tubes, have been extended following ways: (i) mass is now rigidly imposed by use belows to drive flow, (ii) homogeneity states tubes investigated means number carbon thermometers placed along length and (iii) comparison made between results obtained for glass tube metal similar dimensions (inner diameter about 0.2 mm). Well-defined, reproducible steady can generally be both tubes. Special attention paid transport regions which negative differential resistance appears occur occurrence inhomogeneous states, small quantitative as well qualitative differences behaviour
