条件平均是一种从被视为确定性趋势和剩余波动（或概率部分）的组合的突发或准周期现象中提取典型波形的技术。本文提出了一种新的条件平均技术，这是从所谓的模板方法，允许自动选择，使用相关性分析，相同的事件的现象的扩展。将该方法应用于线性磁化等离子体中观测到的准周期振荡，成功地将该现象分为确定性趋势和剩余波动。此外，对残差波动功率的统计误差分析揭示了确定性趋势和残差波动之间存在相互作用。
The conditional average is a technique to extract a typical waveform from bursty or quasi-periodic phenomena regarded as a combination of deterministic trend and residual fluctuations (or probabilistic part). The article proposes a new conditional average technique that is an extension from what is called the template method that allows automatic selection, using the correlation analysis, of the identical events of the phenomena. The proposed method is applied on a quasi-periodic oscillation observed in a linear magnetized plasma, and successfully divides the phenomenon into the deterministic trend and residual fluctuations. Moreover, the statistical error analysis on the power of the residual fluctuations discloses the presence of mutual interactions between the deterministic trend and the residual fluctuations.
