对来自Mirnov线圈阵列的信号的双正交分解分析能够提供托卡马克中磁流体动力学（MHD）不稳定性的空间结构和时间演化。这样的分析可以适用于适合于快速真实的时间应用（例如不稳定性检测和中断测量标记计算）的数据采集和细化系统。本文介绍了该技术在弗拉斯卡蒂托卡马克升级（FTU）中的应用。
The biorthogonal decomposition analysis of signals from an array of Mirnov coils is able to provide the spatial structure and the temporal evolution of magnetohydrodynamic (MHD) instabilities in a tokamak. Such analysis can be adapted to a data acquisition and elaboration system suitable for fast real time applications such as instability detection and disruption precursory markers computation. This paper deals with the description of this technique as applied to the Frascati Tokamak Upgrade (FTU).
