The effects of the uniaxial pressure ($P$) are studied by using the pressure-dependent hopping parameters. The system is semi-metallic with the same area of an electron pocket and a hole pocket at $P < 3.0$~kbar, where the energies $(\\varepsilon_{\\rm D}^0$) at the Dirac points locate below the Fermi energy $(\\varepsilon_{\\rm F}^0$) when $H=0$.
