- This shows there is a good linear relation between the spectral intensity and the elemental density
结果表明元素含量与谱线强度之间有良好的线性关系。 - Our cosine correctors couple to optical fibers and spectrometers for relative and absolute spectral intensity measurements , for emissive color applications , and for evaluation of light sources such as leds and lasers
我们的余弦校正器可与光纤和光谱仪连接，用于相对光谱强度和绝对光谱强度测量、发射光谱测量，以及对led光源和激光光源进行评价。 - If the focal point of the len shifts around the surface of the sample , the mass ablation , the temperature of the plasma and the spectral intensity appear asymmetric and their maximum occur at the location which is about 0 . 4mm under the surface of the sample . ( 2 ) to the plasma of the aluminum alloy sample , when the operating voltage is 1600v , the height from the observed location of the plasma to the surface of the sample is 2mm and the argon pressure is 660 torr , the spectral intensity have the maximum values

在进行理论分析和研究的基础上，提出了因血细胞中存在多种荧光团，且这些荧光团的电子能级上又存在大量的不同的振动能级，从而导致被激发的荧光团发出较宽的荧光光谱；血细胞浓度的增大，荧光团以及其他大分子之间的距离变小，造成它们之间因碰撞的能量转移概率加大，因而易产生荧光猝灭，结果导致荧光强度的变小；血细胞溶液中重吸收所导致的荧光猝灭和二次荧光发射，以及血细胞浓度的变化对其中荧光团能级系统的影响都是导致荧光峰值波长“红移”的原因；进而研究了led光诱导血细胞产生荧光光谱的机理。 - First , a new method of ultrasound - modulated optical tomography with real - time fast fourier transformation ( fft ) is reported to improve the detection sensitivity and snr . by discriminating ultrasound modulated information carried by scattering photons , the tomographic images of the biological tissue simulating media and a buried object are reconstructed with fft spectral intensity
