The contents of nearly forty-elements in surface sediments in Jiaozhou Bay were determined using a Neutron Activation Analysis Technique(Grancini,et al.,1976;Li Peiquan et al.,1985,1986;Li Xiuxia etal.,1986).This paper's detailed discussion on only nine elements(Fe,Mn,Co,Cr,Sc,As,Sb,Zn andV)includes their distributions,concentrations,correlationships,material sources,background,etc.Based on Zavaristski's classification method,Fe,Mn,Co Cr and V belong to the second group;As and Sb to theeighth groups:Sc and Zn to the third and sixth groups.It was found that their notably good correla-tionship is mainly due to the similarity of their ionic structures and that their variation is controlled by theFe content(except Mn).The source of sediments is mainly terristrial material,and the composition ofsediment is similar to that of shale and shale+clay.The contents for a large number of ele-ments are within the scope of the background level,but there still is pollution of Zn and Cr,at least in a few stations. 相似文献

正针对鹤壁市现状,我们局党组一班人进行了深入研究,确定了通过"抓导向,抓问题,抓队伍"来促进"五个国土"建设的总体思路。抓导向,就是要抓目标导向,一般来讲目标是指个人、部门或整个组织所期望的成果。对当前鹤壁国土资源系统来说,就是在全系统高效推进"五个国土"建设,确保"稳增长、调结构、惠民生、防风险"各项任务的顺利完成,促进鹤壁"十三五"规划在国土资源系统的落实,促进鹤壁国土资源局省级文明单位、省级卫生单位创建和基层党组织建设卓有 相似文献

This paper reports the occurrence of a marine brachyuran crab species Eucrate alcocki Serène, in Serène et al., 1973, of the family Euryplacidae Stimpson, 1871, for first time from India, based on a male specimen
from Parangipettai fish landing centre in Bay of Bengal, Southeast Coast of India. Although morphologically corresponding
with what is currently defined as E. alcocki, the color pattern of the carapace of the present specimen is rather different from that of the Chinese material-only the
anterior fifth of the carapace is marked with scattered red spots, the rest of the surface is yellowish, with four unusually
shaped red blotches which almost look like Sanskrit characters. 相似文献

对偶理论是最优化理论的重要组成部分,具有深刻的理论意义和重要的应用价值。针对多目标规划问题的对偶问题,在F-凸,ρ-凸和(F,ρ)-凸的基础上对(F,α,ρ,d)-凸和广义(F,α,ρ,d)-凸条件下的多目标规划问题进行了研究,将多目标非线性规划问题的Wolfe向量对偶,Mond-Weir型向量对偶和混合型向量对偶的弱对偶定理中的凸性条件弱化。在较弱的凸性((F,α,ρ,d)-拟凸,(F,α,ρ,d)-伪凸,弱(F,α,ρ,d)-拟凸)条件下,给出并证明了相应的弱对偶定理。通过弱化凸性条件,从而扩大了多目标规划的实用范围。 相似文献

Monthly investigatiom were made on the population of Chinese freshwater crab, Sinopotamon yangteskiense Bott, 1967 from April, 1984 to Match, 1985. The data on 4413 specimens show that the growth was affected mainly by temperature. During the April to November growth period, the crabs' major development occured from June through October. One year was required for a fine white oocyte to develop into a mature egg. The reproduction period was June-October. Females bearing eggs were taken from June-August, and crabs with young were found from July-October. The females reproduced once a year but could for more than one year. The number of eggs carried by a female varied greatly according to the size of the crab, ranging from 30 to 100 eggs. New-bom crabs become mature after 1-2 yeats. The sex ratio was approximately 1:1 in the overall population. However, the larger crabs are predominantly male. The age distribution of S. yangtsekinese was estimated from size frequency histograms. There were more adult crabs 相似文献

纯溪小镇位于平江县连云山.从长沙驱车前往,本以为纯溪小镇在山脚下,没想到却藏在深山,需要盘山4公里,仿入云端,这便是它所在的"连云山脉"名字的由来.我们来到连云山的时候,已经是深夜,看不见苍山却意外收获了星光.山顶的星空漫天,好像伸手就可以摘到,索性把车一停,享受这不可多得的一刻.
不知过了多久,纯溪小镇的木制招牌出现在眼前,我们入住这里唯一的客栈——候街一号. 相似文献

过去接触一些国际组织时深有感触,改革开放以来,中国科学家的情况有很大变化, 在国际组织中担任职务的人愈来愈多。但仍感觉许多国际组织内,中国科学家还是相对人数有限。过去接触一些联合国机构,明显的感到前苏联的人还是比较活跃,而且他们有意识地做培养工作,让他们到国际组织中去工作,工作一段以后又回到苏联,拿到一个学位,又可以在国际组织再往更高的位置上升。那时我感觉,我们国家对这方面工作注意得不够。改革开放以来,这方面情况有很大的变化。我非常同意陈述彭、廖克同志谈的一些意见。 相似文献

正时间已经来到2014年的下半年,不知不觉已经是我在省国土资源厅工作的第四个年头了。记得还在江西省国土资源厅工作期间,我去一个县局出差,那时我已确定被湖南省厅录用。县局局长从上世纪八十年代开始就在国土系统工作,席间大家闲聊起我的经历,这位已经在国土 相似文献
