Advances in Polar Science 2024年

作者： FANG Xiaoyue HU Shugang wang yanqing ZHANG Zishang TAO Zhencheng YANG Guang College of Safety and Environmental Engineering Shandong University of Science and Technology Key Laboratory of Marine Ecology and Environmental Sciences Institute of Oceanology Chinese Academy of Sciences Engineering Technology Department Institute of Oceanology Chinese Academy of Sciences Qingdao University of Science and Technology Laboratory for Marine Ecology and Environmental Science Qingdao National Laboratory for Marine Science and Technology University of Chinese Academy of Sciences Center for Ocean Mega-Science Chinese Academy of Sciences

This study investigates the composition, abundance, and basic biological parameters of krill in Prydz Bay, the Antarctic Peninsula and the Amundsen Sea by analyzing samples and environmental data from the Chinese National Antarctic Research Expeditions conducted between 2009/2010 and 2019/2020. The predominant krill species observed were Euphausia superba, Euphausia crystallorophias, and Thysanoessa macrura. T. macrura, although the most widespread, exhibited the lowest mean abundance(9.96 ind·(1000 m–3)) and biomass(0.31 g·(1000 m–3)), predominantly found in low-latitude regions of the Amundsen Sea while E. crystallorophias was most concentrated in polynyas of Prydz Bay. E. superba, with an average abundance of 34.05 ind·(1000 m–3)and biomass of 11.80 g·(1000 m–3), was mainly distributed in the Antarctic Peninsula and Prydz Bay. This study also identified regional variations in mean body length and frequency distributions of krill. The relationship between krill body length and wet weight followed a power-law pattern. Regional differences were observed in the relationship between krill abundance, biomass, and environmental factors with varying correlations. In the Amundsen Sea, no significant correlation was found between krill abundance and environmental factors. Notably, E. crystallorophias in Prydz Bay demonstrated a significant positive correlation with chlorophyll-a concentration,while T. macrura abundance and biomass in the Antarctic Peninsula exhibited a significant negative correlation with ice-free days. The findings contribute valuable regional data on krill distribution, abundance, and biomass in the Southern Ocean, serving as foundational information for the conservation of the Southern Ocean ecosystem and Antarctic krill fishery management on a circumpolar scale.

Annals of Applied Mathematics 2024年第3期 285-313页

作者： Yulin Ye yanqing wang Huan Yu School of Mathematics and Statistics Henan University College of Mathematics and Information Science Zhengzhou University of Light Industry School of Applied Science Beijing Information Science and Technology University

In this paper, we are concerned with the minimal regularity of both the density and the velocity for the weak solutions keeping energy equality in the isentropic compressible Navier-Stokes equations. The energy equality criteria without upper bound of the density are established for the first time. Our results imply that the lower integrability of the density ρ means that more integrability of the velocity v or the gradient of the velocity ?v are necessary for energy conservation of the isentropic compressible fluid and the inverse is also true.

在旋转机械设计中,准确预测轴-盘转子的非线性振动至关重要.在已有研究中,盘通常被视为刚体,以简化转子非线性问题.本文旨在阐明盘柔性对轴-盘转子非线性动力学响应的影响.考虑了陀螺效应和离心效应.轴基于Euler-Bernoulli梁理论并考虑von Kármán非线性,盘基于Kirchhoff板理论.利用Lagrange方程推导出了运动微分方程.采用拟弧长延拓法对偏心质量激励下的转子非线性受迫振动响应进行了数值分析.通过与已有文献的对比,验证了本文模型的正确性.探讨了盘柔性和盘位置、半径和厚度以及轴壁厚、长度对转子非线性振动的影响.结果表明,只有在非常有限的情况下,才可以忽略盘柔性,在大多数情况下,忽略盘柔性会过高估计转子的非线性振动幅值,因而使得轴-盘转子的设计偏于保守.
