the results have shown that the fwhm of light scattering spectrum intensity of bubbles can be used as the criterion of the density and size of bubbles in water. the method may find ma…
研究表明,光散射谱强度分布的半值宽度可以用作为检测水中气泡存在的判据,具有较高的实用价值。
the conclusion is that, when the length of fiber is fixed, different frames lead to different threshold, and the fwhm is different.
得出在光纤长度一定时,腔结构的改变导致腔损耗及激光产生阈值的改变,进一步导致激射中心波长fwhm变化的结论。
that transmission rate and the fwhm of the fiber grating fp are very sensitivity for radial strain. but the central wavelength, mode number of the fiber grating fp are insensitivity for radial strain.
发现光纤光栅f p干涉仪的透射率和光谱半宽度对轴向应变十分敏感,而f p腔的中心波长和工作模式却变化较小。
the theoretic analyses show that the full width at half maximums(fwhm) of different slopes are the same, that is the fwhm of confocal axial response is irrelevant to tilt angle.
理论分析表明共焦轴向响应的半极值宽与被测表面的倾角大小无关。
with the stress increased, two peaks were split apparently and the fwhm broadening of the pl peaks appeared.
同时pl峰的半峰宽随着应力增加而逐渐加大。
finally given are our detailed work results. we get the fwhm and ee of the yunnan observatory 1m optical telescope.
最后给出的是试验步骤和最终结果,我们初步得到了评价天文光学望远镜成像质量的综合指标。
although a number of factors control the fwhm of a stellar image (like focusing, telescope optics, and vibrations), it is usually dominated by the seeing.
虽然影响fwhm的因素很多(例如:焦点是否实,望远镜光学系统以及振动),但通常是受到视宁度的影响。
during lcf test, the fwhm of m(211) decreases, the drop of fwhm of m(211) is linearly related with temperature of fatigue and original hardness of the steel.
低周疲劳过程中钢的m(211)峰半高宽也减小,其减小的幅度与疲劳温度和其初始硬度线性相关。
