查询词典 separations

X-rays are used because they have the same wavelength as the atomic separations so the crystal acts as a molecular diffraction grating to diffract a beam of X-rays, producing a diffraction pattern that can be captured and analyzed.

之所以使用X射线是因为其波长和原子裂解时的波长一样，所以晶体作为分子衍射光栅衍射X射线，产生一种可以获取并分析的衍射图形。

For critical separations, specificity can be demonstrated by the resolution of the two components which elute closest to each other.

对于临界分离，专属性应通过相邻出峰的两个组分的分离度来证明。

In particular,peripheral contrast enhancement with separations of an intradural extramedullaty tumor on MRI will suggest the diagnosis of schwannoma.

椎管内髓外硬膜下神经鞘瘤的MRI特征，有助于椎管肿瘤的鉴别诊断，尤其是伴有瘤内分隔性周围强化，应提示神经鞘瘤。

Although most workers have found that samples containing ionizable components usually are best separated with mobile phases that have a pH less than or equal to 3 , some separations may be impossible at a low pH because components of the sample are unstable at a low pH; protonated basic compounds are eluted too soon; and required band spacings are unobtainable.

尽管许多工作者发现含有离子化组分的样品在流动相pH值低于或等于3的时候有最佳的分离，但许多样品不可能在低pH下分离，因为样品中组分在低PH下不稳定、质子化的生物碱洗脱太快、和不能达到要求的峰间距。

Two power separations fiscal thinking is that with the modern enterprise system, but back in Jinshang era, Jinshang to use such system.

两权分离的理财思想，是现代企业所遵从的制度，但早在晋商时代，晋商就采用了这样的制度。

Its use is usual ly restricted to preliminary work in which products will be held for additional separation at a later time, when most of the volatile component must be removed from the hatch before it is processed further, or for similar noncritical separations.

它的使用项目前期工作提供限制的产品将在为另外的分离晚些时候，当大部分的挥发性成分除去孵化之前进一步处理或类似非临界的分离。

With the short capillary length, the system was capable of performing rapid separations which, combined with the noninterrupted sample introduction, resulted in high sample throughputs of 50/h.

通过短管的快速分离与不间断电压CE自动连续进样相结合，微型化的FI-CE-ECL系统可以达到每小时50样的高分析速度。

The peak height precisions for proline, valine and phenylalanine were 1.4％, 5.4％ and 4.3％ RSD (n=9), respectively. With the short capillary length, the system was capable of performing rapid separations which, combined with the noninterrupted sample introduction, resulted in high sample throughputs of 50/h.

毛细管出口、工作电极和光纤的相对位置会影响样品与电生试剂之间的混合和光的收集效率，影响到系统的灵敏度和分离效率，因而对三者之间的相对位置进行了优化。

These kosmotropes may be divided into two groups which act somewhat differently:(1) polyhydroxy compounds fit in well with the hydrogen bonding arrangements, but stabilize any cluster 'flickering' via hydrogen bond rearrangement, as their hydroxyl groups are similarly separated to water-water separations, and (2) zwitterions where the balance between hydrophilicity, hydrophobicity, anionic and cationic characteristics ensures good solubility but only weak net interactions to surrounding water.

这些kosmotropes可分为两个群体行为稍有不同：(1)多羟基化合物符合了氢键安排但任何稳定集束'摇曳'经由氢键重排，由于其羟基同样隔开水水离职，(2)氨基酸的平衡，亲水性，疏水性，阴离子和阳离子特色ensures溶解性好，但只有弱相互作用网，对周围的水。

The basis for membrane separations is the difference in permeability of a semiporous membrane to different molecular sizes .

膜分离技术的基础是不同大小的分子对半渗透膜渗透性不同。

More direct, directer ; most direct, directest

径直的，笔直的
