作为中国小说批评史研究的专门术语,“小说学”相较于“小说理论”“小说批评”和“小说美学”而言,其论述范围更为“宽泛”。“小说学”的内涵包括“三个维度”和“一种体式”:“三个维度”是指小说文体研究、小说存在方式研究和小说文本批评;“一种体式”是指小说评点,这是“小说学”的重要载体。“小说学”的历史书写要突出对小说存在方式的研究、强化对小说研究观念的梳理和凸显小说文本阐释的重要性,以此改变传统小说批评史研究在对象和路径上的“偏狭”。

作者：付永强谭帆华东师范大学中文系上海200241

目前学界普遍认为邝璠在编纂《便民图纂》的过程中,以楼璹《耕织图》为蓝本绘制了《农务女红之图》,并把楼璹的五言诗替换成通俗易懂的竹枝词。这些图像与竹枝词因其通俗性而受到晚明建阳书坊的青睐,并被吸纳到日用类书“农桑门”中,由... 详细信息

目前学界普遍认为邝璠在编纂《便民图纂》的过程中,以楼璹《耕织图》为蓝本绘制了《农务女红之图》,并把楼璹的五言诗替换成通俗易懂的竹枝词。这些图像与竹枝词因其通俗性而受到晚明建阳书坊的青睐,并被吸纳到日用类书“农桑门”中,由此建构出一种耕织图的民间传播谱系。然而借助校勘学方法,仔细分析《便民图纂》和日用类书中的耕织图,就会发现日用类书中的耕织图不是源自《便民图纂》,邝璠也并非《农务女红之图》的作者。日用类书中的耕织图存在大量的沿袭错误、删减割裂、细节缺失等问题,也不可能起到促进耕织技术推广的作用。

为确保用水总量控制下绿洲安全及干旱区可持续发展目标的实现,以新疆开孔河流域为例,提出基于用水总量控制指标、地下水安全等约束条件的干旱区灌溉节水潜力计算新方法。结果表明:1)开孔河流域现状年(2020年)地下水开采量为12.97亿m^(3),灌溉用水总量为34.85亿m^(3);传统节水模式下,流域中期规划年(2030年)节水潜力为0.74亿m^(3),远期规划年(2050年)节水潜力为5.02亿m^(3)。2)在节水潜力新内涵下,开孔河流域中期规划年没有节水潜力,且需要休耕18667 hm^(2),远期规划年节水潜力为1.77亿m^(3)。3)为防止干旱区次生盐渍化,实现水资源短缺的干旱区可持续发展,在节水后应控制绿洲地下水位在3.5~4.0 m之间。对于水土不均衡的干旱区灌区而言,传统节水思路对绿洲安全的重视程度不够,对节水潜力评价过高。

Microstructural rafting of Ni-based single-crystal(SC) superalloys is inevitable at elevated temperatures during long-term service with mechanical loading, which significantly affects the mechanical behaviour of the material. In this study, the effects of rafting on the mesodeformation and fracture behaviour of a Ni-based SC superalloy under cyclic and tensile loads were investigated using in situ scanning electron microscopy(SEM), digital image correlation(DIC), and crystal plasticity finite element method(CP-FEM) simulations. The results indicated that the tensile strength decreased significantly in the rafted specimens. In the cyclic tests, both the virgin and rafted specimens showed an increase in the maximum shear strain with cycle number. The interaction of cross-slip bands was captured by in situ SEM-DIC around the micro-notch of the virgin specimens during the tensile test, while a more homogeneous local deformation field was observed in the rafting specimens. In addition,the fracture behaviour was strongly influenced by the rafting morphology. The crack exhibited instantaneous and long-range fracture features along the octahedral plane as it propagated in the rafting specimen, whereas it deflected over a short distance between the crystallographic planes at an early stage in the virgin specimen, which is consistent with the CP-FEM ***, the CP-FEM results for the crack initiation direction on(111) dominant slip plane were consistent with the in situ SEM observations.
