查询词典 sieve analysis

A two-component carbon tetrachloride system and a two-component aqueous system have been treated with the proposed strategy where only 21 calibration samples are needed, and the result showed that the predictive ability was not obviously impaired for the former system while being clearly strengthened for the latter one in comparison with a conventional way that required a calibration set of 100 samples.5 An unlooked-for experimental observation that in near-infrared spectroscopy the second overtone of aniline adsorbed by 13X molecular sieve nearly disappeared led us investigate a fundamental problem: the behavior of NIR when the outside space surrounding a molecule is too small to allow the molecule to vibrate freely.

同时，最小相关样本设计能进一步减少所需的校正样本数，且能提供更多合适变量以建立多元校正模型。这两方面的改进使模型的预测能力得以提高，其预测精度即使在水体系中也有明显的改善。五、近红外漫反射光谱在线非接触监测气-固吸附过程中出现了一个意外现象，即在近红外光谱上，被13X分子筛吸附的苯胺的二级倍频几乎完全消失了。这促使笔者深入探讨了近红外光谱的空间效应(当一分子被一足够小的刚性空间限制时，其振动的受限导致一级倍频和二级倍频强度均减少，并且后者减少的程度比前者更大)。
