“reptation”的概念、定义、翻译、参考文献-科学参考

reptation

Physics

A motion describing the dynamics of a polymer in a highly entangled state, such as a network. Regarding the entangled state as a set of chains between crosslinks, it is possible to regard the chain as being in a ‘tube’, with the tube being formed by topological constraints. The chain is longer than the tube so that the ‘slack’ of the chain moves through the tube, which causes the tube itself to change with time. This motion was called reptation (from the Latin reptare, to creep) by the French physicist P. G. de Gennes, who postulated it in 1971. Many experiments indicate that reptation dominates the dynamics of polymer chains when they are entangled.

Geology and Earth Sciences

A mode of particle transport in which grains are lifted or ejected only weakly and do not rebound or eject other particles when they return to the bed.

Geography

A method of sand transport whereby grains are set into a low motion due to the high-velocity impact of a descending saltating grain. In this way, grains are set in motion at wind velocities lower than those required to move them by wind alone.
