近年来,历史虚无主义在各界的批驳声中似乎已经偃旗息鼓,但其传播动向发生了由现实向虚拟、由显性向隐性的转变。历史虚无主义以新型网络技术构建的智能媒体平台为渗透环境,以网络意见领袖的助推为渗透渠道,凭借花式伪装渗入不同的网民群体,荼害民众的历史认知。这使人难以觉知,疏于提防,因此其危害性更胜以往,对意识形态工作提出了新挑战,故有必要在剖析成因与进路的基础上进行有针对性的治理。论及历史虚无主义思潮与网络意见领袖合流的原因,舆论热点与现实利益相勾连为其渗透提供了耦合契机,网络技术监管层面的缺失、网络主体价值引领的缺乏进一步助长了渗透行为,网络意见领袖道德匮乏和素养局限导致的失范行径则在一定程度上发挥了“催化剂”的作用。在实践进路上,网络意见领袖主要凭借其在话语引导力、话语解释力以及话语影响力等方面的优势,助推历史虚无主义跨层向外扩散、歪曲历史事实以及诱发意识形态风险。对此,应当通过揭批错误思潮的谬论与宣传主流文化的观念铸牢民众的思想基础,通过培育复合型的意见领袖人才与组建主流的意见领袖队伍强化意识形态工作的主导权,通过培育网民的媒介素养与加强网络平台的监治清理网络空间,综合施策应对“合流”乱象,还网络空间一片天朗气清。

苦乐观是人生观的重要组成部分,体现了个体对自我生存意义的探寻,而当前部分大学生的“摆烂”现象反映了其苦乐观的消极倾向。通过对当代大学生的“摆烂”现象进行分析,可以发现部分大学生在苦乐观方面存在以下表征:片面理解苦乐内涵与关系的怀疑倾向,苦乐态度不端与情感消极为表征的颓废悲观倾向,苦乐信念缺乏与意志薄弱的精神虚无倾向以及苦乐动机功利与行为脱节的精致利己主义倾向。借助积极心理学相关理论探讨大学生苦乐观教育,有助于消解大学生“摆烂”症候,帮助大学生辩证对待人生苦乐矛盾,树立积极向上的苦乐观。

Feasibility analysis of soft constraints for input and output variables is critical for model predictive control(MPC).When encountering the infeasible situation, some way should be found to adjust the constraints to guarantee that the optimal control law exists. For MPC integrated with soft sensor, considering the soft constraints for critical variables additionally makes it more complicated and difficult for feasibility analysis and constraint adjustment. Therefore, the main contributions are that a linear programming approach is proposed for feasibility analysis, and the corresponding constraint adjustment method and procedure are given as well. The feasibility analysis gives considerations to the manipulated, secondary and critical variables, and the increment of manipulated variables as well. The feasibility analysis and the constraint adjustment are conducted in the entire control process and guarantee the existence of optimal control. In final, a simulation case confirms the contributions in this paper.

Data-driven soft sensor is an effective solution to provide rapid and reliable estimations for key quality variables online. The secondary variables affect the primary variable in considerably different speed, and soft sensor systems exhibit multi-dynamic characteristics. Thus, the first contribution is improving the model in the previous study with multi-time-constant. The characteristics-separation-based model will be identified in substep way,and the stochastic Newton recursive(SNR) algorithm is adopted. Considering the dual-rate characteristics of soft sensor systems, the proposed model cannot be identified directly. Thus, two auxiliary models are first proposed to offer the intersample estimations at each update period, based on which the improved algorithm(DAM-SNR) is derived. These two auxiliary models function in switching mechanism which has been illustrated in detail. This algorithm serves for the identification of the proposed model together with the SNR algorithm, and the identification procedure is then presented. Finally, the laboratorial case confirms the effectiveness of the proposed soft sensor model and the algorithms.
