查询词典 microwave spectroscopy

Terahertz radiation, which is a kind of electromagnetic wave between the infrared and microwave bands, belongs to far-infrared band. THz time-domain spectroscopy which developed in the 1980\'s has the advantages of high signal to noise ratio, obtaining the absorption coefficient and refractive index of the sample at one time , low energy that can not distroy the biology organise and so on.

太赫兹辐射是指频率位于微波和红外光之间的电磁波，属于远红外波段；20世纪80年代发展起来的THz时域光谱技术，具有信噪比高，能同时获得样品的吸收系数和折射率，能量低，不会对生物组织造成破坏等优点，在材料和生物学等领域得到了迅速的发展和广泛的应用。

Characterization of cotton fiber using solid-state ~(13)C-CP/MAS NMR spectroscopy shows that the crystallinity after MHT is lower than the original sample,but the cotton after MHT has a higher lateral orientation index,which has a good definition in C2,3,5 resonance region.~(13)C-CP/MAS NMR spectroscopy and X-ray diffraction reveal that cellulose I_βis the main cellulose in cotton,and microwave change the allomorphs content.

通过核磁共振碳谱表征分析可知，微波处理之后的结晶度要小于原样，但是由于微波处理之后的棉纤维有相当高的侧向有序指数，其在C2，3，5共振区域有更好的清晰度。X衍射和核磁共振均表明棉纤维是以纤维素I_β为主，微波处理改变了纤维素的晶型，晶型含量I_α和I_β均降低，但是比例基本保持不变，微波处理之后向次晶转化。
