| 1 | Spatial heterogeneity and source apportionment of soil metal(loid)s in an abandoned lead/zinc smelter显示文摘Metal smelting have brought severe metal(loid)s contamination to the soil.Spatial distribution and pollution source analysis for soil metal(loid)s in an abandoned lead/zinc smelter were studied.The results showed that soil was contaminated heavily withmetal(loid)s.The mean of lead(Pb),arsenic(As),cadmium(Cd),mercury(Hg)and antimony(Sb)content in topsoil is 9.7,8.2,5.0,2.3,and 1.2 times higher than the risk screening value for soil contamination of development land of China(GB36600-2018),respectively.Cd ismainly enriched in the 0–6mdepth of site soil while As and Pbmainly deposited in the 0–4mlayer.The spatial distribution of soil metal(loid)s is significantly correlated with the pollution source in the different functional areas of smelter.As,Hg,Sb,Pb and copper(Cu)were mainly distributed in pyrometallurgical area,while Cd,thallium(Tl)and zinc(Zn)was mainly existed in both hydrometallurgical area and raw material storage area.Soil metal(loid)s pollution sources in the abandoned smelter are mainly contributed to the anthropogenic sources,accounting for 84.5%.Specifically,Pb,Tl,As,Hg,Sb and Cumainly from atmospheric deposition(55.9%),Cd and Zn mainly from surface runoff(28.6%),While nickel(Ni)mainly comes from parent material(15.5%).The results clarified the spatial distribution and their sources in different functional areas of the smelter,providing a new thought for the risk prevention and control of metal(loid)s in polluted site soil. | Yunxia Zhang Tianshuang Li Zhaohui Guo Huimin Xie Zhihao Hu Hongzhen Ran Changzhou Li Zhichao Jiang | 2023 | Journal of Environmental Sciences2023，，5： | 5 |
| 2 | An adaptive reanalysis method for genetic algorithm with application to fast truss optimization显示文摘尽管为结构的优化的基因算法(GA ) 是很柔韧的,它比 optimality 标准和数学编程方法很计算地集中、因此慢。加快设计过程,在场的作者为 GA 的一个适应分析方法和它在最佳的设计的应用捆绑。这种分析技术首先从樱桃酒鈥檚 被导出联合近似方法。一个重复计划被采用适应地在每代决定基础向量的数字。以便说明这个方法,三个古典例子最佳捆绑设计被用来验证建议基于 reanalysis 的设计过程。介绍数字结果证明适应分析技术很稍微影响最佳的解决方案的精确性并且确实加速设计进程,特别为大规模结构。关键词捆绑结构 - 适应分析 - 基因算法 - 快优化工程被中国(50975121 ) 和吉林的毕业生革新资金的工程 2009-2007 的国家自然科学基金会支持大学。 | Tao Xu Wenjie Zuo Tianshuang Xu Guangcai Song Ruichuan Li | 2010 | Acta Mechanica Sinica2010，26，2： | 2 |
| 3 | Transportation of dynamic biochemical signals in non-reversing oscillatory flows in blood vessels显示文摘Biological processes and behaviors of endothelial cells on the inner surfaces of blood vessels are regulated by the stimulation from biochemical signals contained in the blood.In this paper,the transportation of dynamic biochemical signals in non-reversing oscillatory flows in blood vessels is analyzed by numerically solving a nonlinear governing equation for the time-dependent Taylor-Aris dispersion.Results show that the nonlinear frequency-amplitude modulation of the transportation of biochemical signals is more(less) significant when the frequency of an oscillatory flow is close to(higher than) that of an oscillatory signal.Under steady flow,the transfer function for the signal transmission system is obtained,showing that the system is a low-pass filter.Lower inner radius or higher center-line velocity of a blood vessel increases the cutoff frequency of the transportation system.These results suggest the possibility and condition for the 'remote' transmission of low-frequency dynamic biochemical signals in pulsatile blood flows. | ZHU Yong LI YiZeng QIN KaiRong TANG Hong QIU TianShuang | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，2： | 2 |
