Abstract: First,some theories of supersymmetry and quantum gravity in particle physics are stated briefly.This paper introduces a super-spin,which is independent of spin,and super-isospin and various supersymmetric transformations,so that describes unification between bosons and fermions.Further,various unifications of different interactions and other aspects in supersymmetry and superstring are discussed.The four quantitative conclusions on the loop quantum gravity are derived.Finally,a possible existence of the extensive spring for different scales from superstring to cosmic string is proposed.

Key words: particle physics, supersymmetry, superstring, loop quantum gravity, unification
