LLE data of cyclooctane/3-methylpentane + benzene/toluene + N-methylpyrrolidone (NMP) at 298.15 Kand 313.15 K under a pressure of 101.3 kPa were measured in this work. The Othmer-Tobias and Handequations were adopted to validate the reliability of LLE data, where the correlation coefficients (R2) wereclose to unity, indicating the high reliability of the experimental data. The experimental data were analyzed using the distribution coefficient (D) and separation factor (S), and the effect of NMP extracting benzene and toluene from aromatics was explored. Meanwhile, the reason for the different extractionefficiencies of benzene and toluene using NMP was analyzed by quantum chemical calculations. TheNRTL and UNIQUAC thermodynamic models were used to correlate the liquid–liquid equilibrium data,and the relevant binary interaction parameters were obtained. The calculated root mean square deviation(RMSD) were all less than 0.0063, indicating that the obtained binary interaction parameters can be usedto simulate and calculate the extraction of aromatics using NMP.

A troubling feedback loop, where drier soil contributes to hotter climates, has been widely *** study, drawing on climate model simulations, reveals that maintaining current global soil moisture levels could significantly alleviate 32.9% of land warming under low-emission scenarios. This action could also postpone reaching critical warming thresholds of 1.5 °C and 2.0 °C by at least a decade. Crucially,preserving soil moisture at current levels could prevent noticeable climate change impacts across 42%of the Earth's land, a stark deviation from projections suggesting widespread impacts before the *** combat soil drying, afforestation in mid-to-low latitude regions within the next three decades is proposed as an effective strategy to increase surface water availability. This underscores the substantial potential of nature-based solutions for managing soil moisture, benefiting both climate change mitigation and ecological enhancement.

文中以某船坞工程采用的新型三排桩支护结构作为依托工程,结合地质勘察报告,运用有限元分析法和弹性支点法对其典型断面的桩前被动土压力计算公式参数进行了反演分析.通过改变土体参数、开挖深度,以及前排桩桩径等影响因素,对比分析计算得到桩前土压力有限元计算值与弹性支点法计算值的比值变化规律.结果表明:被动土压力合力的模型计算结果E_(p模型)与理论公式计算结果E_(p理论)的比值约为0.4~0.7.在此基础上,对三排桩支护结构桩前土压力的弹性支点法公式进行了改进,为修正系数提出了合理建议,改进后公式为:p_(s)=(0.4~0.7)(k_(s)v+p_(s0)),并研究了各系数的分布规律.

为探究3-癸烯-2-酮对马铃薯的抑芽作用,本试验以陇薯7号马铃薯为试验材料,以不做任何抑芽处理为对照,采用0.15 mL·kg^(-1)的3-癸烯-2-酮对萌芽期马铃薯进行熏蒸处理,考察3-癸烯-2-酮处理0~5 d对芽眼部位分生组织和生理指标的影响,并分别对处理后48和72 h的马铃薯样品进行转录组分析。结果表明,3-癸烯-2-酮处理后1~2 d,芽分生组织逐渐坏死,3~4 d完全坏死。与对照相比,3-癸烯-2-酮处理组块茎呼吸速率增加,超氧阴离子(O_(2)^(-)·)、过氧化氢(H_(2)O_(2))含量升高,抗氧化酶活性降低,丙二醛(MDA)和蛋白质羰基含量增加。3-癸烯-2-酮处理使得编码9-LOX基因下调表达,改变了植物激素水平,并使光合作用中叶绿体电子传递系统发生紊乱,从而影响果胶甲酯酶活性,改变细胞壁稳定性,最终引起分生组织细胞在短时间内发生膜质过氧化而抑制马铃薯发芽。在此过程中,谷胱甘肽代谢和苯丙烷生物合成通路对氧化胁迫做出了响应。本研究结果可为进一步探索3-癸烯-2-酮抑制马铃薯发芽的分子机制提供参考。
