  The Born cross section and dressed cross section of $e^+e^-$ to $b\bar{b}$
and the total hadronic cross section in $e^+e^-$ annihilation in the
bottomonium energy region are calculated based on the Rb values measured by the
BaBar and Belle experiments. The data are used to calculate the vacuum
polarization factors in the bottomonium energy region, and to determine the
resonant parameters of the vector bottomonium(-like) states, the Y(10750),
Upsilon(5S), and Upsilon(6S).
