Abstract: Under the assumption of linear field,the equation of the two-dimensional configuration of corona loop or the corona archide may be given as Δψ+G(dG/dψ)=-4π(dp/dψ), which is solved by using the method of Foriour transformation.The analytical solution is applied to explain the observational results.The theoretical results show that the pressure should be uniform along the-loop,and the configuration of the loop is more stable than that of the force free field.The influence of the shear magnetic field and the pressure on the configuration are also discussed.More magnetic energy of shear or twisted magnetic field may be stored in the loop,the corona loop will be driven to produce the corona transient process or the plasma will be heated or accelerated to produce solar flares if part of the stored energy is released.
