| 英文摘要 | A new magnetopause model is proposed based on observation results, in which the magnetic field includes one constant component and one monotonically increasing component, so that magnetic field shear exists during the intervals when the interplanetary magnetic field has a northward component. Under this model, a completely analytical self-consistent equilibrium distribution function is derived based on the Vlasov-Maxwell equations. Through the analysis of this distribution function and its moments, the following on be concluded: (i) The equilibrium distribution function consists of a homogeneous Maxwellian distribution and two inhomogeneous shifted-Maxwellian distributions. There are ''hole'' and ''bump'' structures which have different cross-field drift velocities in the velocity distribution. (ii) The density decreases monotonously from the outside of the magnetopause to the inside. (iii) The electrical current distribution is a typical current sheet structure. (iv) Under a certain condition of temperature parameters, the thickness of the magnetopause may be larger than the ion gyroradius. These results are applicable to the region of the low-latitude magnetopause during the intervals when the interplanetary magnetic field has a northward component. |
