通过重新考察女性病患在诊疗过程中的缄默行为可以发现,在明清医疗实践中,礼教意识并非刻板的界限。女性病患的声音在医疗场景中的缺失并不意味着她们在现实诊疗活动中的沉默。更重要的是,女性亲属在这一场景中与医者的正常交流揭示了“礼教”与“沉默”之间简单推导关系的矛盾性。女性病患的缄默行为绝非遵从于刻板的规则,而是充满流动性的选择。在此基础上,由于礼教的力量并非人们想象中那么强大,情感被作为一种重要的工具在医疗场景中对女性病患起到规诫作用。女性与欲望之间原本局限于医学理论的关联性,经过历史的重构实现了文化价值的转向。这种解释模式使得女性疾病的身体形成一种隐喻,预示着她们嗜欲的行为,从而令羞耻感得以实现其规诫作用。

Interest has recently emerged in potential applications of (n, 2n) reactions of unstable nuclei. Challenges have arisen because of the scarcity of experimental cross-sectional data. This study aims to predict the (n, 2n) reaction cross-section of long-lived fission products based on a tensor model. This tensor model is an extension of the collaborative filtering algorithm used for nuclear data. It is based on tensor decomposition and completion to predict (n, 2n) reaction cross-sections; the corresponding EXFOR data are applied as training data. The reliability of the proposed tensor model was validated by comparing the calculations with data from EXFOR and different databases. Predictions were made for long-lived fission products such as 60Co, 79Se\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{79}} {\mathrm{Se}}$$\end{document}, 93Zr\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{93}}\mathrm{Zr}$$\end{document}, 107P\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{107}}\mathrm{P}$$\end{document}, 126Sn\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{126}}\mathrm{Sn}$$\end{document}, and 137Cs\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepack
