主　　题：In Temperature Dependence of the Unperturbed Dimension of Polydimethylsiloxane 

摘      要：Internal energy changes accompanying thehigh elastic deformation of rubber-like materialshave been of much recent *** Ptitsyn as well as Flory,Hoeve andCiferri have derived the following relationfor the fractional contribution to the tension byinternal energy effects, f_U,to the total tensionf of rubber during extension,(f_U)/f=1-(/)_=,whereis the mean square end-to-end dis-tance of the uncrosslinked rubber moleculeunperturbed by long range interactions,andT is the absolute *** the Flory-Fox theory of intrinsic viscosity,we have
