A study of reflectivity-measurement in far ultraviolet and vacuum ultraviolet 盲肠后腹膜外阑尾炎远紫外及真空紫外反射率测量的研究
Astronomers found the halo using NASA's Far Ultraviolet Spectroscopic Explorer ( FUSE) satellite to peer beyond the edges of our home galaxy. 天文学家是使用美国航空航天局的远紫外线光谱探测仪(FUSE)卫星,在我们所居住的星系边缘外发现此日冕的。
The results of electronic microscope scanning of sub-micrometer patterns by far ultraviolet lithography are given. 并给出远紫外光刻亚微米级图形的电镜扫描照片结果。
The AlN film has an excellent preferred ( 100) orientation structure, intense absorption in the far ultraviolet ray range of 200& 300 nm, and high transmission in the wavelength range of 300-1 000 nm. 结果表明:利用磁控溅射方法可以获得(100)择优取向AlN薄膜;AlN薄膜在200~300nm远紫外光范围内具有强烈的吸收,在300~1000nm波长范围内具有良好的透过率。
The Raman spectra of calf thymus DNA in aqueous solution with 2 and 16-hour UV-A radiation were presented to study the damage of DNA molecules by UV-A radiation, which was far less than that with the whole ultraviolet radiation. 检测了小牛胸腺DNA水溶液经2h和16hUV-A区段紫外辐射的拉曼光谱。实验结果表明,该区段紫外辐射对DNA的影响要比全波段紫外辐射的影响小得多。
Spraying drugs, irradiating wound with far infared rays and sterilizing wound with ultraviolet rays punctually are controlled by a microcomputer. 该机采用微机控制喷药、远红外线创面烘烤并自动定时进行紫外线创面消毒。
The Experimental Study of Far Ultraviolet Lithography 远紫外光刻的实验研究
It is something like the existence of far infrared, infrared and ultraviolet regions outside of the visible light region. 这儿有可能象原子光谱中的可见光区域的两侧存在远红外,红外与紫外区域一样。
So far, most photocatalytic materials are semiconductors with wide band gap, which only absorbs ultraviolet light and limits the utilization of solar energy. 迄今为止,大多数用于光催化的材料都是宽带隙半导体,只能吸收紫外光,对太阳能的利用受到极大的限制。
