宇文所安提出“非虚构诗学”一说,认为中国诗歌的意蕴不可能脱离其字面传达出的现实情境感受。但学者常将之误解为依照字面死板解读。在宇文所安的界定下,“非虚构诗学”含有现世、实感双重意蕴,可以通过“兴”之“引譬连类”思维,用诗歌在现世的物、我、社会、宇宙,以及今、古之间建立共感网络,并影响现实。宇文所安等学者根据“非虚构诗学”的现世感性,反对讽寓解读《诗经》注疏。但他们过于注重主观感受,贬抑史学考据在诗歌解读中的重要性。中国传统“以史证诗”方法可以修正“非虚构诗学”的这一缺失。

奥尔巴赫思想的一大关键是喻象现实观,他提倡“客观化的主体”,即主体通过感性领会事件并做出行动而合于历史真理。喻象的构成与诠释都有赖这一意识,而最能体现奥尔巴赫喻象现实观的,是他的但丁研究。与弗里切罗认为奥尔巴赫观点不适用... 详细信息

奥尔巴赫思想的一大关键是喻象现实观,他提倡“客观化的主体”,即主体通过感性领会事件并做出行动而合于历史真理。喻象的构成与诠释都有赖这一意识,而最能体现奥尔巴赫喻象现实观的,是他的但丁研究。与弗里切罗认为奥尔巴赫观点不适用于《神曲·天国篇》相反,奥尔巴赫对贝亚德的诠释表明,《天国篇》中的感性与真理通过贝亚德的喻象交融。没有尘世经历的贝亚德,反而引起但丁对她的尘世感性记忆,使尘世情爱贯穿但丁求索真理的旅途,并成为后者领悟的契机。通过贝亚德喻象,文学人物但丁、作者但丁与《神曲》读者共同得到成全,而奥尔巴赫的喻象现实观也淋漓尽致地呈现在其中。

随着人口老龄化、透析技术的提升,血液透析患者中老年人的比例越来越高,随之伴发的老年综合征在透析患者临床实践管理中需要引起重视。常见的老年综合征,如衰弱、肌少症、营养不良、躯体功能障碍、认知功能障碍及抑郁情绪,在血液透析患者中具有较高的患病率,并且与不良预后相关。对老年血液透析患者进行老年综合评估,能够早期识别高风险患者并进行分层管理,对改善患者预后及提高生活质量具有一定的指导意义。

以金山店铁矿机制砂为研究对象,对2种不同种类母岩机制砂分别开展X射线衍射试验、筛分试验和抗压强度试验,并与黄砂进行对比。试验结果表明,母岩为火成岩的机制砂喷射混凝土抗压强度最高,黄砂次之,沉积岩最低;长石含量是影响机制砂混凝土强度的主要因素,其次矿物的结晶结构和晶粒大小也影响机制砂强度;沉积岩机制砂母岩强度高、细度模数大,机制砂混凝土抗压强度与黄砂混凝土相比降低了14.4%;建议选用长石含量高,抗压强度适中的岩石制备的机制砂来作为井下喷浆用砂。

This study aimed to examine the effects of inoculating Fritillaria taipaiensis P.Y.Li leaves with different strains ofpotassium-solubilizing bacteria (KSB), or combinations thereof, focusing on aspects of photosynthesis and physiologicaland biochemical characteristics. At present, some studies have only studied the rhizosphere microbialcommunity characteristics of F. taipaiensis and have not discussed the effects of different microbial species on thegrowth promotion of F. taipaiensis. This paper will start from the perspective of potassium-solubilizing bacteria toconduct an in-depth study. Seed cultivation commenced at the base with three different KSBs in early October2022. The growth of F. taipaiensis leaves was observed after different treatments. Both single-plant and compoundinoculations were executed. A total of eight treatment groups were established, with aseptic fertilizer and sterilizedsoil functioning as the control group. The results reveal that intercellular CO_(2) concentration (Ci), stomatal conductance(Gs), and transpiration rate (Tr) were at their apex in the S7 group. Most treatment groups exhibited anincrease in leaf area, photosynthetic pigment content, soluble sugar, soluble protein, Superoxide Dismutase(SOD), Peroxidase (POD), Catalase (CAT) activities, and proline content. The expression levels of POD, SOD,and CAT genes were evaluated, following inoculation with different KSB. The highest was the S7 group. Theinoculation with various KSB, or combinations thereof, appears to bolster the growth and development of F. taipaiensis.The composite inoculation group S7, comprising Bacillus cereus, Burkholderia cepacia, and Bacillus subtilis,manifested the most favorable impact on the diverse indices of F. taipaiensis, thereby furnishing valuableinsights for the selection of bacterial fertilizer in the artificial cultivation of F. taipaiensis.

An experimental study of compressible mixing layers(CMLs)was conducted using planar laser Mie scattering(PLMS)visualizations from condensed ethanol droplets in the flow.Large ensembles of digital images were collected for two flow conditions at convective Mach numbers Mc=0.11 and 0.47.The coherent vortices,braids and eruptions in the mixing zone were observed,interpreted as evidence of multi-scale,three-dimensional structures at a high Reynolds number.The mixing layers with a large visualized range present two stages along the streamwise direction,corresponding to the initial mixing and the well-developed stage.A new method,the gray level ensemble average method(GLEAM),by virtue of the similarity of the mixing layer,was applied to measure the growth rate of the CML thickness.New evidence for a nonlinear growth of CML is reported,providing an interpretation of previous observations of the scattering of the growth rate.

Fritillaria taipaiensis P.Y.Li is a widely used medicinal herb in treating pulmonary diseases.In recent years,its wild resources have become scarce,and the demand for efficient artificial cultivation has significantly increased.This article is the first to apply phosphate solubilizing bacteria isolated from the rhizosphere soil of F.taipaiensis P.Y.Li to the cultivation process of F.taipaiensis P.Y.Li.The aim is to identify suitable reference strains for the artificial cultivation and industrial development of F.taipaiensis P.Y.Li by examining the effects of various phosphate solubilizing bacteria and their combinations on photosynthesis,physiological and biochemical properties,and gene expression related to the protective enzyme system in F.taipaiensis P.Y.Li.The experiment,conducted in pots at room temperature,included a control group(CK)and groups inoculated with inorganic phosphorussolubilizing bacteria:W1(Bacillus cereus),W2(Serratia plymuthica),W12(Bacillus cereus and Serratia plymuthica),and groups inoculated with organophosphorus-solubilizing bacteria:Y1(Bacillus cereus),Y2(Bacillus cereus),Y12(Bacillus cereus and Bacillus cereus),totaling seven groups.Compared to CK,most growth indices in the bacterial addition groups showed significant differences,with W12 achieving the highest values in all indices except the leaf area index.The content of photosynthetic pigments,photosynthetic parameters,and osmoregulatory substances increased variably in each bacterial treatment group.W12 exhibited the highest content of chlorophyll a and soluble protein,while W1 had the highest free proline content.The activities of peroxidase(POD),superoxide dismutase(SOD),and catalase(CAT)in all inoculated groups were higher than in CK,with significant changes in SOD and CAT activities.The malondialdehyde(MDA)content in all inoculated groups was lower than in CK,with Y12 being the lowest,at approximately 30%of CK.Gene expression corresponding to these three enzymes also increased variably,with POD expression in Y2 being the highes

NonLocal Means(NLM),taking fully advantage of image redundancy,has been proved to be very effective in noise removal.However,high computational load limits its wide application.Based on Principle Component Analysis(PCA),Principle Neighborhood Dictionary(PND) was proposed to reduce the computational load of NLM.Nevertheless,as the principle components in PND method are computed directly from noisy image neighborhoods,they are prone to be inaccurate due to the presence of noise.In this paper,an improved scheme for image denoising is proposed.This scheme is based on PND and uses preprocessing via Gaussian filter to eliminate the influence of noise.PCA is then used to project those filtered image neighborhood vectors onto a lower-dimensional space.With the preproc-essing process,the principle components computed are more accurate resulting in an improved de-noising performance.A comparison with some NLM based and state-of-art denoising methods shows that the proposed method performs well in terms of Peak Signal to Noise Ratio(PSNR) as well as image visual fidelity.The experimental results demonstrate that our method outperforms existing methods both subjectively and objectively.

目的分析老年体检人群高尿酸血症(HUA)和肾功能的相关性。方法本研究为横断面研究,选取2020年8月至2021年6月于北京友谊医院进行健康体检的503例老年人为研究对象,收集一般资料及实验室检查,应用logistic回归分析HUA的影响因素,采用Spearman相关分析、多元logistic回归分析HUA和肾功能的相关性。结果老年人HUA的发生率为19.9%,多因素logistic回归发现,饮酒(OR=1.785,95%CI:1.087~2.932)、体重指数(OR=1.133,95%CI:1.046~1.226)、高密度脂蛋白胆固醇(OR=0.107,95%CI:0.036~0.316)及eGFR(OR=3.290,95%CI:1.699~6.370)是HUA的影响因素。Spearman相关分析显示,老年人血尿酸水平与肾小球滤过率呈负相关(r=-0.278,P<0.001),在调整饮酒史、年龄、体重指数及高密度脂蛋白胆固醇后,多元logistic回归分析发现,HUA组出现eGFR<60 ml·min^(-1)·(1.73 m^(2))^(-1)的风险高3.019倍(95%CI:1.450~6.284)。结论饮酒、体重指数、高密度脂蛋白胆固醇及肾功能异常均会增加老年HUA的发生风险,HUA是老年人肾功能异常的独立危险因素。
