  We proposed a general transformation in probabilistic teleportation, which is
based on different entanglement matching coefficients $K$ corresponding to
different unitary evolution which provides one with more flexible evolution
method experimentally. Through analysis based on the Bell basis and generalized
Bell basis measurement for two probabilistic teleportation, we suggested a
general probability of successful teleportation, which is not only determined
by the entanglement degree of transmission channels and measurement methods,
but also related to the unitary transformation in the teleportation process.
