MIlD燃烧是一种在中度或极度低氧环境下发生的温和燃烧模式,兼具高燃烧热利用率和极低NOx排放的优势,国际燃烧领域认为它是拥有巨大应用潜力的清洁燃烧技术之一。自1990年左右开展相关研究以来,对于实现气体燃料的MIlD燃烧的相关技术已相对成熟,而关于煤粉和生物质等固体燃料的MIlD燃烧机制和实现条件的研究仍相对缺乏。基于高动量氧化剂射流来实现内部再循环,不再需要外部高温预热来建立MIlD燃烧,极大拓宽了MIlD燃烧的应用范围。从颗粒弥散、受热、着火、燃烧、污染物等方面概述了MIlD粉体燃料燃烧的基础特性,由于颗粒的不均匀弥散和反应,煤粉等碳基固体燃料的MIlD燃烧进程较气体燃料更复杂。高速射流MIlD燃烧在增加点火延迟的同时也扩展了点火区和反应区,需要对燃烧各阶段的特征和机理开展系统研究。介绍了固体燃料MIlD燃烧理论设计和装备研发领域所取得的研究成果,建议通过高精度数值模拟,改进现有燃煤锅炉燃烧器、调节工艺参数以匹配MIlD燃烧模式,增加焦炭颗粒的停留时间以提高燃烬率,提高燃烧稳定性并抑制包括细颗粒物在内的各类污染物排放。基于互联能源系统的整体方法,推进MIlD燃烧与各类新型燃烧技术的耦合研究,尤其加强煤粉、生物质与氢、氨等可燃气体共燃特性研究,助力能源转型。探究粉体MIlD燃烧中的湍流两相流特征、湍流相间传热作用以及湍流-化学耦合作用是加深对粉体MIlD燃烧理解的关键,涉及多变量分析和高精度模拟,是未来研究的重点和难点。

现有对葛兰言亲属制度理论的研究试图将葛兰言放在以列维-斯特劳斯为轴的谱系之中,着力强调葛兰言对亲属制度普遍理论的贡献。然而,对葛兰言的解读并非只有结构主义这一个角度,其对亲属制度的贡献还有其他源流、线索与对话者。首先,葛兰言继承并超越了涂尔干所确立的研究传统,继续探究外婚制的起源问题,以及婚级组织的转换问题;其次,对葛兰言亲属制度研究的探讨不该脱离其整体的理论视野与研究目标,即探寻以互惠为原则的亲属组织向以声望为原则的封建组织的转变过程;最后也最重要的是,从其社会学视野出发,葛兰言的亲属制度理论基于其对《仪礼》这一文本的重新理解与阐释,这种理解是对“正统”儒家理论中父子关系地位的解构,也伴随着对古代中国亲属关系演进的理论重构。

葛兰言的作品有一条主线——社会凝聚及其演化,这一主线的学术背景应该首先定位于20世纪初法国社会学与历史学关于方法论的论争,这是葛兰言以社会学范式来书写长时段历史的学术实践。葛兰言认为,中国社会从上古时期到封建时期经历了社会凝聚及其原则的演化,从乡村宗教中约婚群体的互惠原则到神话时代政治群体的声望原则,再到封建秩序中多种社会凝聚形式与原则相互交叠,声望原则被荣誉原则抑制和平衡,此时,政治群体和亲属群体也彻底难分彼此。葛兰言跨越《诗经》研究、神话研究、礼仪文本和亲属制度研究,只是为了不断追随这一基本的问题线索。对葛兰言工作的整体性理解为我们呈现了从“社会学年鉴学派”的理论预设出发所确立的历史社会学范式。这个范式借助中国文献所刻画的社会形态,既为我们利用现代社会科学研究中国经典文本提供了一条可行之道,也为重新理解中国上古时期的历史提供了重要的理论启发。
