  The transformation of space-time $x_{\mu}$ and ${x_{\mu}}^{\prime}$ in the
two inertial reference frames $\sum$ and
  ${\sum}^{\prime}$ in which their relative velocity is less than light speed,
and the relation of a particle mass $m$ with its movement velocity
  $v$ and so on are expatiated by Einstein's special theory of relativity.
  In this paper, we set forth a new transformation of space-time $x_{\mu}$ and
${x_{\mu}}^{\prime}$ in two inertial reference frames in which their relative
velocity is equal to or more than light speed, the new relation of a particle
mass $m$ and energy $E$ with its velocity $v$ $(v \geq c)$, the new mass-energy
equation and the new dynamics equation of a particle.
