By choosing suitable parameters, several new and convergentseries are obtained.
适当选取参数，得出了几个新的收敛级数。
2
The MHD equilibrium solutions of a toroidal plasma with non-circular cross-section and linear current distribution are written in terms of a fast convergentseries.
用一个收敛很快的级数构造了非圆截面、线性电流分布环形等离子体的磁流体平衡解。

By algebraic dynamical method, the exact analytical solutions of the ordinary differential equations are obtained in terms of Taylor series with local convergent radius.
