在捷克斯洛伐克超现实主义运动的两次高潮中,符号学与马克思主义的交锋与对话发挥重要作用。20世纪20–30年代,受布拉格学派符号功能论影响,以“旋覆花社”为主的左翼先锋诗人结合日常生活诗学、技术唯物主义、弗洛伊德主义提出“诗歌主义”构想,受到恪守“社会主义现实主义”的马克思主义者的批判。20世纪50–60年代,以斯维塔克、埃芬伯格、史云梅耶为代表的战后超现实主义实践者致力于寻求先锋形式与社会批判间的对话,在“捷克新浪潮”电影实验的激活下,推动人道主义马克思主义与符号学的结合。捷克超现实主义运动是考察捷克马克思主义符号学变迁的棱镜,具有别于其法国同道的文化本土性。

保罗·策兰在其诗人生涯中一直对源始语言立足于何种时间性结构保持追问,而海德格尔基于时间存在论的诗学思想为其提供了诸多启发。海德格尔的境域时间揭示出一个兼涉历史生成性和本真神圣性的存在,策兰将其转述为一种“时间性永恒”的辩证法,并在诗歌创作中切近这种“时间性永恒”。但在策兰看来,海德格尔时间存在论的深层旨归仍然导向一个具有终极意义的存在原乡,其立足荷尔德林展开的诗意栖居论也隐含了某种同一性专断。诗的时间性不应导向存在的本源,而应不断否定与超克自身,指向匿名的陌异。

绿色能源的可持续发展是我国实现3060双碳目标的重要路径,但新能源出力波动大、补贴到位滞后等问题影响新能源发展。绿色证书交易是在市场机制的调节下提升新能源发电收益的有效手段,因此研究绿证交易模式下虚拟电厂的运行优化策略。首先,在购买侧,发电厂商以售电、绿证收益最大为目标,虚拟电厂运营商以购电、绿证成本最低为目标,构建虚拟电厂与发电商之间的主从博弈模型;然后,在出售侧,虚拟电厂运营商以售电、绿证收入最大为目标,用户以综合成本最小为目标,构建虚拟电厂与用户之间的动态博弈模型。最后,采用CPLEX求解器对模型进行求解,通过算例可知,参与绿证交易能够同时扩大发电商利润及虚拟电厂收益,更好地促进了发电商、虚拟电厂运营商、用户之间的合作关系。
