1) F-K spectra
F-K 谱
2) similar 2D F-K spectra
似二维F-K频谱
1.
Extending original length of spatial distance,thickening spatial and wavenumber sampling and taking out certain spectra by similar 2D F-K spectra can eliminate noise and alias,and also enhance the amplitude.
针对上述问题,提出了一种改进插值方法,即扩大原来的空间距离长度,使空间波数采样变密,然后根据似二维F-K频谱图里取中间某一范围的频谱值,就可以去掉噪声和假频,振幅也可得到很好加强。
3) the f(a) spectrum
f(a)谱
5) correlative spectrum
F-F 相关谱
1.
The structure of fluorine-containing functional groups in photographic compound is studied with NMR ~(19)F spectrum and F-F correlative spectrum.
我们采用核磁共振~(19)F 谱和 F-F 相关谱对照相化合物中的含氟官能团进行了结构研究。
6) Optical spectrometers (F)
