Abstract

The concept of electromotive field appears in various applications in space and astrophysical plasmas. A review is given on the electromotive field highlighting our current understanding of the theoretical picture and the spacecraft observations in interplanetary space. The electromotive field is a key concept to successfully close the set of turbulent magnetohydrodynamic equations and also to construct a more complete picture of space plasma turbulence. Applications to astrophysical cases (Earth magnetosphere, heliospheric shocks, interstellar medium, and relativistic jets) are also briefly introduced, as well.

摘要

电动势的概念出现在空间和天体物理等离子体的各种应用中。本文综述了电动势，着重介绍了我们目前对理论图景的理解以及在行星际空间中的航天器观测结果。电动势是成功闭合湍流磁流体动力学方程组以及构建更完整的空间等离子体湍流图景的关键概念。文中还简要介绍了其在天体物理情形（地球磁层、日球层激波、星际介质和相对论喷流）中的应用。
