摘　　要：本文以硝基甲烷为碱中心分子探针,应用脉冲色谱技术和TPD法探讨一系列氧化物催化剂表面碱中心的情况,获得若干有趣的结果.Up to date, there is no satisfactory method to measure the strength and number of basic centers of metal oxides. Based on the theory of selective intermolecular force, a new method of applying nitromethane as molecule probe (it's-NO2 group being very weak, nearly inert) with gas chromatographic and TPD technique has been proposed in this paper, because the C=O group of acetic acid in the previous adsorption method may interact with metal ion and then may interfere the measurement of basic centers.
