来自未对准黑洞-吸积盘系统的相对论等离子体喷流将不是轴对称的。在这里，我们分析非轴对称的，固定的，平移不变的喷流在无力近似场能量占主导地位的粒子能量。我们推导出一个流方程，这些配置涉及的通量函数$\psi$的横向磁场，沿沿着射流的磁力线的线速度$v（\psi）$，和纵向磁场$B_z（\psi）$。当$时，方程可以完全解出。|v| =1$，当$|v| E^2$。最后，我们写下具体的解决方案，近似的数值计算结果的非轴对称喷流产生的旋转黑洞在外部，错位磁场。
The relativistic plasma jets from a misaligned black hole-accretion disk system will not be axially symmetric. Here we analyze nonaxisymmetric, stationary, translation invariant jets in the force-free approximation where the field energy dominates the particle energy. We derive a stream equation for these configurations involving the flux function $\psi$ for the transverse magnetic field, the linear velocity $v(\psi)$ of field lines along the jet, and the longitudinal magnetic field $B_z(\psi)$. The equations can be completely solved when $|v|=1$, and when $|v| E^2$. Finally, we write down specific solutions approximating numerical results for the nonaxisymmetric jet produced by a spinning black hole in an external, misaligned magnetic field.
