The results show that the dynamic stability analysis can be replaced by quasi-static method with the static load multiplying an amplification factor in calculation.
结果表明：在实际计算中，可以将静载乘以某一“放大系数”作为计算荷载进行拟静力分析。

The existence of carbonyl group in structure seems to be a factor that favors the formation of quasi-molecular ion (QMI) or other adduct molecular ion (OAMI) in positive mode.
化合物结构中羰基的存在似有利于化合物在正离子模式下形成准分子离子或其它分子加和离子。

A kind of one -dimensional quasi-periodic grating is designed. Theselfsimilar diffraction spectra are evaluated and the influence of the phason strength onthe structure factor is studied.
