We also point out that the effect of the presence of spectator electrons for the diagram lines is the main contribution of the formation of quasi - continuum spectra Sa波长范围内的半连续x射线谱峰，并且揭示了半连续谱峰的形成机理是由于旁观电子的存在。
From a demand for further amount of aggregate transmission capacity , not only expanding an available wavelength range but also cramming frequency - spacing have been investigated 考虑到将来信息传输容量的急剧增长，因此不仅要拓宽可复用的波长范围，而且信道间距也需进一步降低。
By the late 1980s , scientists had learned that methane traps more heat than an equivalent concentration of co2 because it absorbs a wider range of wavelengths of earth ' s outgoing radiation 1980年代后期，科学家即知道甲烷捕捉的热大于等浓度的二氧化碳，因为散发自地球的辐射中，甲烷能吸收的波长范围较广。
It is found that all the thin films have a preferential c - axis orientation . with increase of al doping , the peak position of the ( 002 ) plane is shifted to the low 2 value 同时, zno通过掺杂,对其带隙进行调整,使探测器的吸收截止边按需求被控制在特定的波长范围内,将成为zno基紫外探测器研究中新的热点。
In this paper we expatiate the importance of using the x - ray to detect the laser - produced plasmas and developing the two - channel elliptical crystal spectrometer ( tcecs ) in the 620 ~ 6200 - ev x - ray region 本文阐述了利用x射线谱进行激光等离子体诊断和国家863军口主题研制用于探测0 . 2 ~ 2nm波长范围的x射线谱的双通道椭圆弯晶谱仪的重大意义。
With each grating , you consider its groove density ( which helps determine the resolution ) , its spectral range ( which helps determine the wavelength range ) and its blaze wavelength ( which helps determine the most efficient range ) 对每个光栅都要考虑其条纹密度（有助于确定分辨率） 、光谱覆盖范围（有助于确定波长范围）以及闪耀波长（有助于确定最佳效率范围） 。
The o - azo / cnts nanocomposites show better photosensitivity than the bulk material in the visible and near - ir region , as well as enhancement effects in photo - response in the visible and near - ir region ( 470 - 800 nm ) 研究发现该复合材料体系在可见光区和近红外光区( 470 800nm )均有光谱响应，光谱响应范围得到了拓宽，并在该波长范围内的光电导性能有大幅度提高。
Because of its excellent electro - optic effect , very short electro - optical response time , and wide transparent wavelength range , linbo _ 3 material meet the demands of low - loss , low drive voltage , high - speed and wide - band intensity modulator 由于linbo _ 3材料具有良好的电光效应、很短的电光响应时间、较宽的透明波长范围,因而适合于制低损耗、低电压、高速宽带强度调制器。
Two - segment distributed feedback ( dfb ) semiconductor lasers can achieve tuning with single longitudinal mode in a certain wavelength range ; at the same time , its superiority also includes bistablity and wavelength conversion 其中，两段式分布反馈( distributedfeedback ， dfb )半导体激光器可以在一定波长范围内实现单纵模、可调谐工作；同时，它还具有双稳、波长转换等功能。
A gas - jet - type vuv source that can give a spectrum in the wavelength range of 5 ~ 200nm was used in this paper to research of vuv radiation effects on upilex films which used as canopy of the space inflatable antennas and al / kapton films 利用射流式真空紫外地面模拟设备研究了5 200nm波长范围内的真空紫外辐照对al / kapton薄膜与空间充气展开天线透射面材料upilex薄膜的性能影响。
