查询词典 higher-pressure region

Because of the absorption of ozonosphere existing in higher level atmosphere,the sun-blind-region ultraviolet radiation (200～280nm) of solar spectrum could hardly reach the surface of the earth. Therefore, the communication system using this spectral coverage could hardly be disturbed.

由于地球大气上层臭氧的吸收作用，阳光中的日盲区(200～280nm)辐射几乎无法到达地球表面，因此，采用这个波段的光学通信系统几乎不会受到太阳光的干扰。

The distribution of tropospheric ozone of east asia show higher in the middle region and lower in the north and south side.

夏季臭氧的分布表现为中间高，南北两边低的特点，夏季平流层输送影响比秋季小。

The following main results are obtained: The TiO_2 photocatalyst with small crystallite size, high surface area, narrow and uniform pore size distribution, and microporous frameworks could be prepared out by applying MW radiation in the preparation process. The microwave-induced fluorescence technique verified for the first time that microwave enhanced the formation rate of hydroxyl radical, leading to the increase in the photocatalytic efficiency. Compared with the conventional catalyst, TiO_2 prepared by MW dielectric heating owns a higher UV absorption ability, and its optical absorption edge and photovoltaic response are shifted toward the short wavelength region, resulting in increase of photooxidation efficiency. The photocatalytic conversion and the mineralization ratio of acetaldehyde are increased respectively by 30% and 40% over the TiO2 prepared by MW radiation when compared to the TiO2 prepared by the conventional heating. For the MW-assisted photocatalytic reaction over the MW-prepared TiO2, production of hydroxyl radicals is enhanced by 22.5%, and the photocatalytic conversion is accordingly increased by 20%. Similarlly, applying MW also increased the photocatalytic conversion and the mineralization ratio of acetaldehyde over TiO2/Al2O3 sample.

论文得到如下主要结果和结论：(1)微波介电加热TiO_2 溶胶可得到晶粒度小、光催化活性高、比表面积大和孔径分布窄而均一，且微孔发达的TiO_2光催化剂；在溶胶干燥处理过程中微波可使催化剂表面缺陷增加，进而导致光催化反应过程有更多的活性羟基自由基产生；(2)微波制备能显著增强TiO_2 样品的紫外光吸收率，并使其光吸收和光伏响应阈值发生蓝移，从而提高TiO_2的氧化还原能力；(3)与常规加热法所制TiO_2比较，微波法制备的TiO_2对乙醛的光催化降解转化率提高30%，CO_2生成率提高40%以上；(4)与未加微波辐射时相比，发现在光催化反应过程中施加微波，TiO_2 的羟基自由基生成速率提高了22.5%，相应CH_3CHO 光催化降解转化率提高了20%；对Al_2O_3/TiO_2催化剂，CH_3CHO 光催化降解转化率甚至提高了33%，同时CO_2 的生成率也都大幅度提高；(5)微波辐射可改变光催化降解乙醛的产物分布，推断施加微波时乙醛光催化降解按照羟基自由基引发的链式反应机理进行，微波&非热效应&起主要作用。

Because of the high discharge current, the thickness of this region is very thin, the electric filed is much higher than that of the cold cathode glow discharge.

由于大电流放电效应，使得阳极位降区厚度很薄，因而相对于常规辉光放电而言，阳极区的电场强度比较高。
