It is based on the measurement of the free induction decay ( FID) signal of the solid phase ( protein and carbo hydrate) and the liquid phase ( oil) of oilseed. 它是测量油料种子的固相(蛋白质和碳水化合物)和液相(油)的自由感应衰减(FID)信号。
Free induction decay signals were transferred into one-dimensional NMR spectrogram via 32 k Fourier transformation. 自由感应衰减信号经过32k傅立叶变换转为一维NMR谱图。
Free Induction Decay Quantum Beating in Eu ∶ Y_2O_3 Powder 稀土粉末Eu∶Y2O3的自由感应衰减量子拍
It has been shown that the optical free induction decay in hollow slab optical waveguides has a lot of different properties from those in non-waveguides. 结果表明:与非波导情况相比,空心平板光波导中的光学自由感应衰减有许多不同的性质。
Measurement of NMR transverse relaxation time of water protons in blood cells by using free induction decay signal 利用FID信号直接测量血细胞中水质子的NMR横向弛豫时间
This chapter starts from the history and characteristics of the low-field NMR, then introduces the phenomenon of nuclear magnetic resonance free induction decay ( FID) signal and spin-echo signal and their obtaining principle, and the entire experiment measuring devices and circuit analysis. 这一章从低场NMR的历史、特点出发,介绍了核磁共振现象中自由感应衰减(FID)信号和自旋回波(spin-echo)信号的获得原理、整个实验系统的测量装置和电路分析。
