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.
