The dependence of emission spectra line intensity and electronic temperature and FWHM ( the full width half maximum ) on the space and pressure of buffer gas are studied. 研究了原子发射谱线强度、电子温度和半高全宽(FWHM)随空间、缓冲气体压力变化的规律。
With the increase of the periods and the absolute value of refractive index difference, the full width at half maximum of spectrum decreases. 介质折射率差的绝对值越大、周期数增加都使透射波谱宽度变窄。
The relationship between air pressure giving birth to bubbles and the full width at half maximum ( FWHM ) of light scattering spectrum intensity is investigated experimentally. 提出了测量水中气泡光散射特性的一种新方法,利用光散射谱强度分布的半值宽度随产生气泡气压的变化测量水中气泡的分布情况。
The effect of acid - base medium and temperature on full width at half maximum intensity were discussed. 并探讨了酸碱介质与检测温度对17O-NMR谱线半峰宽的影响。
The recovery coefficient and the full width at half maximum of the hot lesion were measured. 由图像热灶的恢复系数及半高宽分析部分容积效应。
