    网络口碑由于具有不受时间限制、双向性并且规模巨大等传播特征,其对消费者的影响已经越来越受到各界的重视。但同时,网络口碑由于发送者的匿名性和关联性弱等原因,导致内容特征方面与传统口碑有明显差异。文章在文献研究基础上全新构建内容特征的理论结构,并通过收集数据验证了内容特征的相关性、可靠性和完整性三个维度对消费者购买意愿的影响。最后,通过优势分析发现与传统口碑明显不同的是,内容特征的相关性和完整性比可靠性对购买意愿有更明显的影响作用。教育部人文社科青年项目:在线消费者渠道转换行为的研究——基于网络购物平台的分析(项目号:13YJC630154

    在355nm激光波长下应用多光子电离和分子束技术研究了乙腈和氨水的混合团簇,所得的团簇离子以(CH3CN)n^+、(CH3CN)nNH3^+和(CH3CN)n(NH3)^+为主,中性团簇以二元团簇(CH3CN)n(NH3)m/(CH3CN)n(NH4OH)m为主.离子产物是来源于中性的二元团簇先吸收部分激光能量解离成稳定的小团簇和碎片,然后再发生分子蒸发和电离的过程,并未发生明显的质子转移反应

    The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
