| 英文摘要 | the dynamics and conformations of a single fluorescently stained t4 dna molecule are studied in a random flow of elastic turbulence created by the same unlabeled molecules. the explored polymer concentration covers the dilute and semi-dilute unentangled regimes, according to the measurement of the longest relaxation time by extension relaxation of single polymer chains. the criterion of the coil-stretch transition was found to be close to the theoretically predicted value. using measured polymer stretching statistics and its known elastic properties, the elastic stress in elastic turbulence is obtained over a broad range of weissenberg number and polymer concentration. the existing theory of elastic turbulence is disproved by the measurements of the elastic stress and the degree of polymer stretching. the role of increasing shear rate on polymer extension and angular statistics in a random flow is also studied and compared with theory and numerical simulations. |
