高频率的

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。

Pass " of word of antonym word coupling or the statistical analysis that ","OR" uses a case actually in daily language, can see,"Or the meaning;" that " comparing "OR" conveys " of extract of " of logistic coupling word on taller frequency or after " and "OR" are advanced exchangeability respect difference is not big;"OR" compares " perhaps " more is upper the tendentiousness; that reveals a choice serves as antipathic choice,"OR" compares " or " show is more apparent.

概要： 通过对语词联结词"或者"、"OR"在日常语言中实际使用情况的统计分析，可以看出，"或者"比"OR"在更高的频率上表达逻辑联结词"析取"的涵义；"或者"和"OR"在前后项的可交换性方面差别不大；"OR"比"或者"更多地表现出选择的倾向性；作为不相容选择关系的"OR"比"或者"其前后项更多地满足逻辑排中律；在和其他联结词的相互转化方面，"OR"比"或者"表现更为明显。

Methods 65 patients were scanned in brain with magnetic resonance spectroscopy,the location and the size of region of interesting and other scanning parameters values （FOV,frequency matrix,phase matrix,saturate cingulum,etc.） were changed intentionally,the values of full width at half maxium and water suppression lever were recorded.A preliminary evaluation of the resulted waves and the relationship between the parameters data and the quality of the MRS waves were probed.
