摘　　要：报道了一系列双环戊二烯基二卤化铝（Ⅳ）及钨（Ⅳ）化合物在７０ｅＶ电离能量下的电子轰击质谱（ＥＩ）及以甘油作底物的快原子轰击质谱（ＦＡＢ），分别总结了其谱图特征，讨论了其碎裂机理，为这类化合物结构鉴定提供了依据。The structure of a series of bis-cyclopentadienyl molybdenum(Ⅳ) and tungsten(Ⅳ) dihalids compounds is studied by electron impact mass spectrometry under 70 eV electron energies and by fast atom bombardment mass spectrometry with glycerol as the matrix. The characteristics of mass spectra have been summerized. The fragmentation mechanisms have been discussed. These mass spectra provide information of structure for these compounds.
