摘要：

Differences in the overall level of tan δ are reported for measurements on high density polyethylene in tension under various gaseous environments. The differences do not appear in torsion. The tentative explanation is offered that the effect is due to thermoelastic relaxations of magnitude dependent upon the thermal properties of the environment. In addition a loss peak in tension is reported occurring at 220K in air but not in nitrogen, argon or helium. © 1979.
