Both of the observed radial velocity and separation being projective values, in order to determine the mass of binary galaxies the average projection factor may be derived by a statistical method.
According to the mapping relation of input and output of the parallel robot, Jacobian matrix of this robot was obtained on the basis of velocityprojection method.
