 note = {application/pdf, We deform the 3-sphere into non-commutative ＄c*＄-algebras ＄S_{￥Theta}^{l}＄ by continuous functions ＄￥Theta' s＄ . We then prove that the fixed point ＄C^{*}＄-subalgebra of the non-commutative 3-sphere ＄S_{￥Theta}^{3}＄ under the action of the unit circle ＄S^{1}＄ is isomorphic to the ＄c*＄-algebra of all continuous functions on the 2-sphere. This means that the non-commutative 3-spheres have Hopf  fibered structures in non-commutative sense.},
