家务劳动中的性别分工

国外社会科学 2006年第5期 103-104页

近十几年来，俄罗斯的社会、经济生活发生了天翻地覆的变化，所有这些变化都触及俄罗斯社会生活和思想领域的方方面面，其中包括两性之间的关系。俄罗斯和西方的学者们所作的研究表明，当代俄罗斯社会出现家务劳动分工和家庭内部关系平... 详细信息

近十几年来，俄罗斯的社会、经济生活发生了天翻地覆的变化，所有这些变化都触及俄罗斯社会生活和思想领域的方方面面，其中包括两性之间的关系。俄罗斯和西方的学者们所作的研究表明，当代俄罗斯社会出现家务劳动分工和家庭内部关系平均化趋势时，过去家庭内部夫妻家务劳动分工中严重的不平等现象减少了，而夫妻二人共同承担家务劳动的现象日趋普遍。形成这种局面的主要原因是女性就业率和职业化程度的不断提高以及女性受教育程度的提高。隐含在这种现象背后的根本原因是人们的社会、心理因素发生了很大变化，而绝不仅限于经济方面的因素。

Applied mathematics and mechanics(English Edition) 2025年第1期46卷 177-192页

this paper examines the transport analysis, including both heat transfer and mass transfer, in hybrid nanofluid flow containing gyrotactic microorganisms towards a curved oscillatory surface. the influence of magnetic fields is also inspected in terms of their physical characteristics. to depict the phenomena of transport, modified versions of both Fick's and Fourier's laws are used. Additionally, the characteristics of both heterogeneous and homogeneous chemical reactions are also incorporated. Utilizing a curvilinear coordinate syst.m. the flow problem is formulated as partial differential equations(PDEs)for moment.m. concentration, microorganism field, and energy. An analytical solution to the obtained flow equations is achieved utilizing the homotopy analysis method(HAm).the effects of significant flow parameters on the pressure and microorganism fields, velocity, oscillation velocity, concentration, and t.m.erature distributions are shown via graphs. Furthermore, the variations in skin friction, mass transfer rate, heat transfer rate, and local motile number due to different involved parameters are presented in tables and are analyzed in detail. Graphical results indicate that the curves of velocity and t.m.erature fields are enhanced as the values of the solid volume fraction variables *** is also verified that the concentration rate field decreases as the values of the homogeneous reaction strength parameter and the radius of curvature parameter increase, and it increases with the Schmidt number and the heterogeneous reaction strength *** outcomes show a favorable response of the motile number to advanced values of the Peclet number, the Schmidt number, the microorganism difference parameter, and the bio-convective Lewis number.

掩护式液压支架的合理选择

煤炭科学技术 1991年第3期19卷 55-58,47页

长壁开采正越来越成为美国地下采煤的重要方法。它的优越性在于其事故率大大低于房柱式采法,而生产率超过了过去5年的1倍,并在今后10年内还可望再翻一番。假如岩层控制得当的话,那末长壁开采的潜力是相当大的,为此必须认真地选择工作面支架和进行采区顺槽设计。工作面支架的购置费约占长壁系统总费用的70％,用最新液压支架装备一个长壁工作面需要6～8百万美元。在困难和变化的地质条件下,这些支架一般只服务几个采区的开采。因此,在支架方面的投资不应太轻率。
