The ethylene gas that contains the acetate ester element can be removed by applying the pulse voltage (Vd=250V, f=500Hz) to the floating multi-electrode device. This cause will be considered as following : the strong electric field formed in the neighborhood of the electrode dissociates OH from the acetate element, and the radical is generated, and the ethylene is reformed by reacting with OH radical. This reforming is extremely possible by a small electric power, because the current hardly flows in this device. Moreover, because secondary pollution is not caused, practicable use to the large-scale preservation warehouse and the movable preservation warehouse can be expected.Here, the structure of floating multi-electrode is that many electrodes between two main electrodes is placed in the matrix state ; and each electrode except main electrode is flouting potential. The discharge of the wide region becomes possible, because the charge accumulated in each floating electrode discharges.

通过对浮动多极装置施加脉冲电压（Vd=250V, f=500Hz），可以去除含有乙酸酯元素的乙烯气体。这一原因可以考虑为：电极附近形成的强电场使OH与乙酸元素解离，生成自由基，乙烯与OH自由基反应重整。这种重整极有可能通过一个小的电力，因为电流在这个装置中几乎不流动。此外，由于不产生二次污染，可以预期对大型保鲜仓和移动式保鲜仓的实际使用。这里，浮动多电极的结构是将两个主电极之间的多个电极置于基体状态；除主电极外，其余电极均为漏电位。由于在每个浮电极中积累的电荷放电，宽区域的放电成为可能。
