Two of three two-level atoms which are initially in the W state are injected into two empty cavities respectively to have resonant interaction with the light field.The dipole squeezing of the two atoms inside cavities under a rotation operation and direct selective maeasurement are compared numerically.The influences of the manipulation and state-selective measurement of the atom outside the cavities on the dipole squeezing of the atoms inside cavities are discussed.The results show,the dipole squeezing of atoms inside the cavities can be controlled by the manipulation of the atoms outside the cavities; when the rotation angle increases from zero to π/2,the term of amplitude Sx displays a changing process from squeeze strengthening to weakening.It indicates that the dipole squeezing of the atoms inside the cavities can be controlled by the manipulation of the rotation angle of the atom outside.
