%X Based on the reviewing of the implements of no-slip boundary conditions for SPH method, it combined the method brought by M. Ellero and viscosity solved by second derivative and analyzed the instability problems which were brought by numerical errors and different evolution methods of the boundary particles when M. Ellero's method was imposed on Poiseuille flow. And then it put forward corresponding resolve methods and some improvements of M. Ellero's method and got more accurate results. Finally, attempted an equivalent method to the improved method and validated by Poiseuille flow.
