摘要

在表面排放臭氧发生器上测量了气体温度的空间分布。利用氦氖激光，用迈克尔逊干涉仪对其进行了测量。臭氧发生器具有薄介质材料板(Al/sub 2/O/sub 3/)的配置，该介质材料板置于条形高压电极和接地电极之间。本实验采用流量为1.5 l/min的氧气生成臭氧，放电功率为0.8 W，臭氧浓度为610 ppm。与此同时，在距离臭氧发生器表面2.2 mm处，平均气体温度的最大增幅约为2℃。

Measurements of spatial distributions of gas temperature and ozone concentration in barrier discharge type of ozonizer

Spatial distribution of gas temperature was measured on a surface discharge ozonizer. It was measured by the Michelson interferometer using He-Ne laser. Ozonizer has a configuration of thin dielectric material plate (Al/sub 2/O/sub 3/) which is put between a stripe shaped high voltage electrode and grounded electrode. In this experiments oxygen gas with flow rate of 1.5 l/min was used for ozone generation, and ozone concentration of 610 ppm was obtained at discharge power of 0.8 W. At the same time maximum increment of average gas temperature was about 2 C at distance of 2.2 mm from the surface of ozonizer elements.
