Total organic carbon and organic carbon stable isotope, biogenic silica, chlorin were measured from a high resolution sediment core to indicate the variation in paleoproductivity and the environmental implications over the past decades （1942 to 1997） in the Changjiang Estuary. Based on these biomarkers, the shift in the phytoplankton community structure in the past decades was discussed in response to the long-term variations in nutrient concentrations and nutrient ratios. The results showed that the δ 13 C values varied from –26.15‰ to –19.5‰, suggesting the combined organic carbon sources of riverine and marine organisms. Based on the biogenic proxies, paleoproductivity changes were categorized into three stages： low production before 1950; an increase in production with the dominance of diatoms during 1950 to 1980, consistent with increasing of nutrient concentrations; a decrease in production after 1980 when the diatom production decreased while the production of non-silicious phytoplankton increased due to high nutrient inputs, and high N/P and P/Si ratios in the Changjiang Estuary. The sedimentation records also indicated that the riverine organic carbon increased since 1980.

乔治·米勒执导的电影《疯狂的麦克斯4:狂暴之路》是一部风格独特的影片。它描绘了一幅环境恶化、资源短缺、军阀割据、战争不断的“末日”图景,讲述了冷酷的逃亡者麦克斯帮助独臂女将军弗瑞欧莎摆脱重兵追击、推翻暴政统治、建立新家园的故事。虽然故事背景设定在未来,但它却与当下环境污染、生态破坏、拜物至上、人性滑坡的现状密切相关。人类目前面临的生态和社会问题不仅是技术和管理问题,更是诗学和美学问题。基于此,本文将从生态美学的观点出发,分析《疯狂的麦克斯4:狂暴之路》的媒体图像背后所暗藏的假设和隐喻,挖掘其蕴含的精神内核和生态审美主题,进而研究该电影所承载的生态审美教育功能。

X-ray drive asymmetry is one of the main seeds of low-mode implosion asymmetry that blocks further improvement of the nuclear per-formance of“high-foot”experiments on the National Ignition Facility[Miller et al.,*** 44,S228(2004)].More particularly,the P2 asymmetry of Au's M-band flux can also severely influence the implosion performance of ignition capsules[Li et al.,*** 23,072705(2016)].Here we study the smoothing effect of mid-and/or high-Z dopants in ablator on Au's M-band flux asymmetries,by modeling and comparing the implosion processes of a Ge-doped ignition capsule and a Si-doped one driven by X-ray sources with P2 M-band flux *** the results,(1)mid-or high-Z dopants absorb hard X-rays(M-band flux)and re-emit isotropically,which helps to smooth the asymmetric M-band flux arriving at the ablation front,therefore reducing the P2 asymmetries of the imploding shell and hot spot;(2)the smoothing effect of Ge-dopant is more remarkable than Si-dopant because its opacity in Au's M-band is higher than the latter's;and(3)placing the doped layer at a larger radius in ablator is more *** this effect may not be a main measure to reduce the low-mode implosion asymmetry,but might be of significance in some critical situations such as inertial confinement fusion(ICF)experiments very near the performance cliffs of asymmetric X-ray drives.

多孔质气体静压轴承相比传统的小孔节流轴承具有更高的承载能力,更好的稳定性及便于加工等优点。应用基于有限体积法的软件Fluent分析偏心率、多孔质材料渗透率、轴承长径比和平均气膜厚度等关键因素对多孔质径向轴承静态性能的影响,分析结果显示,在给定轴承平均气膜厚度的情况下,存在最佳的渗透率区间使得承载能力最大,增加轴承长径比和减小平均气膜厚度均可以提高多孔质径向轴承的承载能力及刚度,但需要根据加工装配工艺要求及实际工况选择合适的参数。设计制造中心供气新形式的多孔质径向轴承,通过仿真得到气膜间隙的压力分布及承载能力,并通过实验验证仿真结果的正确性。仿真和实验结果表明,该结构形式的多孔质径向轴承承载性能优良。
