Magnetic reconnection has been suggested to play an important role in the dynamics and energetics of plasma turbulence by spacecraft observations, simulations, and theory over the past two decades, and recently, by magnetosheath observations of MMS. A new method based on magnetic flux transport (MFT) has been developed to identify reconnection activity in turbulent plasmas. This method is applied to a gyrokinetic simulation of two-dimensional (2D) plasma turbulence. Results on the identification of three active reconnection X-points are reported. The first two X-points have developed bidirectional electron outflow jets. Beyond the category of electron-only reconnection, the third X-point does not have bidirectional electron outflow jets because the flow is modified by turbulence. In all cases, this method successfully identifies active reconnection through clear inward and outward flux transport around the X-points. This transport pattern defines reconnection and produces a new quadrupolar structure in the divergence of MFT. This method is expected to be applicable to spacecraft missions such as MMS, Parker Solar Probe, and Solar Orbiter.

过去 20 年的航天器观测、模拟和理论以及最近 MMS 的磁鞘观测表明，磁重联在等离子体湍流的动力学和能量学中发挥着重要作用。已经开发出一种基于磁通量传输 (MFT) 的新方法来识别湍流等离子体中的重联活动。该方法应用于二维 (2D) 等离子体湍流的陀螺动力学模拟。报告了识别三个主动重连 X 点的结果。前两个 X 点已形成双向电子流出射流。除了仅电子重联的类别之外，第三个 X 点没有双向电子流出射流，因为流动受到湍流的影响。在所有情况下，这种方法通过围绕 X 点的清晰的向内和向外的通量传输成功地识别了主动重联。这种传输模式定义了重新连接并在 MFT 的发散中产生了新的四极结构。该方法有望应用于 MMS、Parker Solar Probe 和 Solar Orbiter 等航天器任务。
