摘要

The correlation between shape and size of linear chains on the simple cubic lattice is investigated using a dynamicMonte Carlo technique. A positive correlation between the asphericity parameter A and the square of the end-to-end distanceR2

as well as that between A and the square of the radius of gyration S2

is found for both RW and SAW chains

indicatingthat a chain conformation of small size is usually more spherical than one of large size. The result can explain why the shape of the SAW chain deviate much more from a sphere than that of the RW chain

and can also explain the similar dependence of size and shape on chain stiffness and on the distance of the first bead of a chain from an infinitely large flat surface.
