摘要：

Cylindrical specimens of L.D. polyethylene were brought to various temperatures above the melting point and rapidly drawn to form filaments. Depending on temperature and stretching rate, surface instabilities were observed. A linear stability analysis was performed in the classical way by first reducing the system equations to an equivalent set which admits a steady-state solution. Both Newtonian and Maxwellian fluids were considered. © 1978.
