等离子体不连续性及其相关物理过程的研究，必须了解它们的方向、运动和厚度。在ISSI原始方法手册[Paschmann和Daly，1998年]（以下简称ISSI SR-001）的第8-12章中，介绍了用于确定这些量的各种单航天器和多航天器方法。自该书出版以来，通过对集群使命数据的分析，对这些方法进行了各种相互比较和归纳。在本章中，我们将简要概述这些发展。迄今为止的应用包括行星际不连续性以及地球的弓形激波，磁层顶和尾电流片。第三章讨论了基于Cluster的曲率计和梯度能力的方法，这些方法对于小型航天器分离是有用的。
Knowledge of their orientation, motion, and thickness is essential for the study of plasma discontinuities and the physical processes associated with them. In Chapters 8-12 of the original ISSI methods book [Paschmann and Daly, 1998], hereafter referred to as ISSI SR-001, a variety of singleand multi-spacecraft methods for determination of these quantities were presented. Since the publication of that book, the analysis of data from the Cluster mission has led to various inter-comparisons and generalisations of these methods. In this chapter, we present a brief overview of these developments. Applications to date have included interplanetary discontinuities as well as Earth’s bow shock, magnetopause, and tail current sheet. Methods based on Cluster’s curlometer and gradient capability, of utility for small spacecraft separations, are discussed in Chapter 3.
