梦境叙事是中国古典小说中极为重要的叙事方式之一,在故事情节的建构上起着重要作用。随着媒介技术和市场导向的发展,网络小说作为古典小说在当代的赓续,对后者的梦境叙事手法进行了有选择的继承和革新。网络小说在古典小说梦境叙事循环与回溯功能的基础上,对叙事视角和涵盖内容等方面进行了多角度创新,其在淡化古典小说中梦境叙事教化功能的同时,放大了梦境叙事在当代网络小说中的情节助力功用,进而完成了从梦境建构方式与梦境表现形式等方面对梦境叙事手法进行的突破性革新。

为明确环烷基稠油在火驱过程中生成焦炭的规律和石油焦炭基本性质,应用动态气流氧化原油装置,开展了环烷基稠油注空气燃烧生成焦炭过程的研究,并对生成的石油焦炭进行了组成和结构表征。研究表明:环烷基稠油在250~300℃开始生成焦炭,随着反应温度升高,焦炭产率逐渐增加,温度达到450℃时,焦炭产率最高,为10.8%;温度为500~600℃时,焦炭的燃烧反应加剧,焦炭收率降至4.6%。电镜观察焦炭为0.05~1.00μm碳层叠加的致密片层结构,以400℃为分界点可以将焦炭分为2类。300~350℃生成焦炭的H/C为0.78~0.82,为含有大量烷基链的氧化焦炭;400℃时裂解反应加剧,稠油成焦过程由加氧反应为主转变为裂解反应为主;400~600℃生成焦炭的H/C为0.33~0.47,为芳香度和石墨化程度更高的裂解焦炭。该研究对环烷基稠油火驱开发点火及火线控制具有一定指导意义。

“五四”乡土小说发生在城乡文明互为参照的交叉坐标系中,呈现出“启蒙”主题下的文明观照姿态。台静农在《地之子》中通过建立含魅与附魅的存在逻辑,形成了“在场”的亡者与生者于精神层面的“对话”式关联体系。以《地之子》为代表的“五四”乡土小说在揭露封建秩序与礼俗思想作为双声对话载体的基础上,反映出其对女性与儿童等底层群体的规训实质,并借助人道主义思想和文化批判意识影响下的底层觉醒态势,回应着这一时期“改造国民性”的时代要求。由此而言,“五四”乡土小说是在文明视角与原乡情感二者的角力作用下,共同构筑了这一时期乡土小说中“反叛”与“眷恋”共存的二重性特质,并藉此形成建构与消解启蒙话语立场的双声对话结构。

在我国地震预警和烈度速报系统中,烈度计被广泛使用。烈度计的频谱特征主要是通过检定实验室进行标定,但在破坏性地震中,烈度计响应特点缺少必要的研究分析。该文以2022年四川泸定M_(S)6.8级地震为例,对比分析了烈度计记录和强震仪记录在噪声水平、信噪比(signal-to-noise ratio,SNR)、高通滤波截止频率(f_(HP))取值以及有效周期范围(T_(max))方面的特点,综合评价了烈度计记录的频谱特征,分析了噪声影响。得到以下结论:在整个频域范围内,烈度计记录的SNR要比强震仪记录平均意义上低一个数量级,可以估计烈度计动态范围较强震仪大致低20 dB;烈度计记录的最佳f_(HP)取值相较于强震仪记录存在更大的不确定性,尤其是在竖直方向上;烈度计记录的最佳f_(HP)取值更大,反应谱T_(max)较传统强震仪记录在水平方向小1~2 s,在竖直方向小3 s左右。该研究结果有助于合理应用烈度计记录,服务地震学和地震工程学相关研究。
