摘　　要：对H2D+通过碳膜后的产物H+和D+的获取与测量,研究了H2D+的同位素效应以及离子穿过固体的尾流效应。H2D+的化学结构得到测定。H2D+的非对称结构得到确认。测量结果与通过其它方式对H2D+的研究结果相一致。The Isotopic Effect and Wake Effects of triatomic molecular ions H^+_3 have been studied by captured and measured the fragments from coulomb explosion of its isotopomer H_2D^+. The chemical structure of H_2D^+ has been determined and the result shows an asymmetry configuration for H_2D^+. It was found that there existed clear isotopic effect and wake effect in the structure of triatomic hydrogen molecular ions. It agreed with other experimental results.

关 键 词：同位素效应 尾流效应 非对称结构 库仑爆炸
