针对实数型群体评价信息有效集结的问题,提出了一种凝聚群体共识的随机聚合模型。考虑实数型群体评价信息直接集结运算并不能有效反映决策环境的复杂多变及不确定性因素的影响,为此将离散的实数型群体评价信息转化为连续型随机变量,以凸显现实中的决策环境、更加细腻地刻画群体价值表达;在此基础上,提出了双重驱动的指标赋权方法,即根据各指标随机信息之间的差异性(差异驱动)和群体共识的一致性程度(共识驱动)进行组合赋权;最后,聚合求解被评价对象之间带有概率特征的可能性排序。该方法可以较全面地集结群体评价信息,从可能性的视角给出合理的排序结论,算例分析验证了方法的有效性和合理性。

关键词：群体评价信息集结随机聚合可能性排序

In this article, an inter-antenna inter-subblock shifting and inversion （IASSI） scheme is proposed to reduce the peak-to-average power ratio （PAPR） in multi-input multioutput orthogonal frequency division multiplexing （MIMO- OFDM） systems. It exploits multiple antennas and subblocks to provide additional degrees of freedom to benefit the system. To reduce the implementation complexity of the proposed scheme, two simple suboptimal schemes are further presented based on the minimum current maximum criterion; one adopts sequential search and the other employs random binary grouping. The simulation results exhibit the effectiveness of these proposed schemes.

针对环境样本特别是生活用水中残留消毒剂成分次氯酸(HOCl)检测方法烦琐这一问题,从经典染料亚甲基蓝入手,开发了可对HOCl进行响应的探针DHUOCl-C。核磁共振氢谱和高分辨质谱的结果表明,已成功制备出DHUOCl-C探针,荧光光谱和吸收光谱等性能测试结果表明,探针不仅响应灵敏(检测限低至1.78 nmol/L),并具备较好的选择性。DHUOCl-C仅专一性地与HOCl响应,不与其他环境水样中可能存在的阴离子、阳离子和氨基酸等物质响应;与HOCl响应后不仅会有明显的荧光变化,5μmol/L的HOCl即可使探针发生肉眼可见的显著颜色变化。在真实环境样本的测试中发现,可通过借助荧光或肉眼直接观察体系的颜色变化,从而对不同来源水样中的HOCl进行识别和检测,结果表明探针可满足生活用水中HOCl便捷化检测的需求。
