Oxidation of soot particles under the silent discharge have studied in the room temperature. The following results were obtained: (1) From the experiment of CO oxidation and observations of emission spectra from the silent discharge, it is found that OH radicals are generated in the dischare reactor. (2) It is found that the soot collected on the filter is oxidized in the silent discharge. (3) In the experiments of flow system, the soot concentration is reduced from 75 mg/Nm^3to 30mg/Nm^3for 3.0 sec of residence time at a supplied electric power of 180 W (4) The soot reduction did not take place in the presence of a large excess of CO concentration over 1400 ppm.

在室温下研究了无声放电条件下碳烟颗粒的氧化.（1）通过CO氧化实验和无声放电发射光谱的观察，发现在放电反应器中产生了OH自由基。(2)研究发现，在无声放电中，收集在过滤器上的碳烟被氧化。(3)在流动系统的实验中，在180 W的供电功率下，停留时间为3.0秒，碳烟浓度从75 mg/Nm^3降低到30 mg/Nm^3。（4）当CO浓度超过1400 ppm时，碳烟的减少不会发生。
