half with at half-maximum
解釋
半峰半寬度-
Another phase, the high temperature phase, is hexagonal with space group p - 62m, which is stable from 300 to 800. the lattice parameter and the full width of half maximum ( fwhm ) of xrd peaks of u3o8 were also investigated at different temperature, and it were found that they change with the temperature under rules
在兩種相結構各自穩定的溫度范圍內， u _ 3o _ 8的點陣參數以及衍射峰半高寬（ fwhm ）出現了有規律的變化，這種變化表明u _ 3o _ 8的晶體結構依賴于環境溫度的變化。 -
( 211 ) reflection of the polycrystal a - iron sample is used in the simulation experiments, and both the resulting full - width - at - half - maximum ( fwhm ) of the diffraction peaks and peak shifts under tensive and compressive strain are in accord with that expected from analytical methods. the instrumental resolution curves, under various combination of the first collimator and second collimator and take - off angle of the monochromator, are given
用- fe多晶樣品的（ 211 ）晶面進行了模擬實驗，得到的衍射峰半高寬以及拉應變和壓應中國原子能科學研究院博士學位論文變作用下衍射峰移動的模擬結果都與解析方法的預期值符合得很好。 -
Theoretical analysis shows : compared with oled, moled with alq3 as light - emitting layer can emit different wavelength light by modulating length of cavity, spectral full width at half - maximum of moled changes from 100nm to 10nm ~ 20nm and the light intensity at peak is increased by about 20 times, and luminous efficiency can be enhanced
理論分析表明：通過調節腔長，用alq3作發光層的moled可以發出不同中心波長的光，譜線寬度由oled的約100nm變為10 ~ 20nm ，峰值光強提高20倍左右，總發光效率也有所提高。 -
