The columns exhibited good separation ability for disubstituted benzene isomers, especially for xylenes and cresols. In addition, the three peralkylated-β-CD columns offer better selectivity than the (2,6-di-O-benzyl)-β-CD column.

同一根柱不同次进样和不同柱之间表现出良好的重复性，保留时间的相对标准偏差小于8.5%；对使用大约40次后的溶胶-凝胶柱重新进行测试，柱效下降不明显，说明该类色谱柱的稳定性良好。

Three rooms with natural ventilation and eleven streets (includes two streets which the viaducts crossed) are selected as sampling points, CO concentration and aerosol particle number concentration are employed as the test parameters for gaseous and particulate pollutants, respectively.

本文分别选择了上海市和西安市的三个自然通风房间和十一条街道(包括两条高架桥穿越的街道)作为典型测试点，并分别以CO浓度和气溶胶粒子数浓度作为测定参数，对室内外污染物浓度间的关系进行了系统的实验测试和详细的理论研究。

It was observed that the reduction behavior of catalysts was dependent on the calcination temperature of their precursors, and the higher ability of hydrogen uptakes has been obtained in the p.
