Below the superfluid transition temperature, the eddy viscosity in addition to the viscosity caused by the normal fluid component was observed when the velocity of cell-wall exceeded the critical velocity. The magnitude of the critical velocity depends on the roughness of the cell wall. In the case of a cell with rough wall, the critical velocity is low compared with a cell with smooth wall.}, pages = {79--88}, title = {超流動ヘリウム4中の量子渦粘性率の測定}, volume = {29}, year = {1994}, yomi = {オガワ, トモユキ and シゲマツ, トシノブ and フジイ, ヨシコ} }
