The European Court of Human Rights(ECtHR)has ruled that illegal indirect entrapment must meet three criteria *** mixed standard requires that the previous direct entrapment violates the“essentially passive,”subsequent indirect entrapment satisfies the“reasonable foreseeability,”and police entrapment of secondary defendants to commit crimes is considered“decisive.”The legal consequences of indirect entrapment are distinguished between general indirect entrapment and illegal indirect *** basic position of the ECtHR on the consequences of illegal indirect entrapment has shifted from supporting mitigating penalties to recognizing procedural dismissal,and general indirect entrapment is considered a mitigating factor in *** the backdrop of increasing internationalization of criminal justice standards,the above criteria and positions have strong implications for the improvement of relevant rules in China.

为解决传统水体pH值预测模型泛化能力差,预测准确度低的问题,提出一种改进思维进化算法(MEA)优化改进极限学习机(ELM)的水体pH值预测方法。在MEA基础上引入混沌理论、莱维飞行及柯西高斯混合变异策略,有效解决MEA早熟、易陷入局部最优的缺点,提高了求解搜索性能。将Morlet小波与反双曲正弦叠加作为ELM的激励函数并引入正则化项,提高了ELM动态逼近性能与泛化能力。将模型运用于太湖水体pH值预测中,实验结果分析表明。相比其他模型,该模型泛化能力好,预测精度高,可为水环境管理与决策提供依据。

为提高近海混凝土的耐久性和钢渣粉在混凝土中的利用率,通过测试掺钢渣混凝土的流动度、凝结时间、力学性能、碳化深度和氯离子电通量,研究了硫酸钠、脱硫石膏、脱硫灰这3种激发剂以单掺或复掺方式对钢渣活性和混凝土抗氯离子能力和抗碳化性能的影响。结果表明:钢渣使水泥净浆的流动度下降,凝结时间延长,Na2SO4作激发剂可略微缩短凝结时间,矿粉和钢渣粉可一定程度减少混凝土坍落度的经时损失,但加入一定量的激发剂后会减弱这种效果;脱硫灰、Na2SO4、脱硫石膏这3种激发剂对混凝土的抗折强度有显著提升,特别是3%Na2SO4对抗折强度的贡献较大;Na2SO4与脱硫石膏复合激发剂对混凝土抗折强度的提升作用大于Na2SO4-脱硫灰复合激发剂和单掺激发剂;3种激发剂单掺对钢渣-矿粉混凝土7 d抗压强度略有改善效果,对后期抗压强度的改善效果不明显,但复合激发剂对混凝土抗压强度的提升较为显著,特别是3%Na2SO4和4%脱硫石膏复合激发剂对力学性能的提升效果较为显著;Na2SO4使混凝土的抗碳化性能和抗氯离子渗透性能分别提高了23.9%和43.7%,Na2SO4和脱硫石膏复合激发剂对耐久性的提升效果优于单一激发剂。脱硫灰、脱硫石膏、Na2SO4激发剂提高了钢渣的活性,进一步改善了混凝土的微结构,使得混凝土的力学性能和耐久性能提升。
