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

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

The waters with salinity from 10 to 23 comprise the main removal region of ion and particulateforms of heavy metals in the Changjiang estuary.The positive correlationships between Zn,Cd,Pb,Cuand the reciprocal of transparency,COD and chlorophyll-a showed that the removal of heavy metalsclosely correlate with the distribution of suspensions,the adsorption of organic materials and theassimilation by organisms.The removal of heavy metals in the Changjiang estuary water were consistentwith the sedimentation rate of the sediments in these waters,sediment types and the distributions ofheavy metals contents in the sediments.  相似文献

Potassium, sodium, magnesium and iodine requirements of shrimp, Penaeus chinensis were studied.Orthogonal design was employed in this experiment. The composition of the basal diet consisted of fishmeal, peanut cake, corn meal, soybean cake, wheat bran, vitamin mix and mineral mix, and supple-mentations of potassium, sodium, magnesium and iodine in the basal diet were made according to theL_9(3~4) orthogonal table. The results indicatal that iodine supplementation improved growth of the shrimpsignificantly and raised survival very significanly, iodine requirement of the shrimp was 0.003%, sodiumrequirement was 0.87% or less; and that 1.1-1.3% potassium and 0.18-0.38% magnesium in the dietwere proper nutrition supplements for the shrimp.  相似文献

哦,父亲     
<正>我之所以想写这篇文章,是因为父亲并不是我的生父。父亲来到我们家时,我的年纪还很小。依稀记得,那时的我还没有上学,整天吊着鼻涕,脸上抹着灰土,领着弟弟和一群小伙伴或翻墙或踏青,或执树枝撵打村里的狗,整天到处疯跑。父亲来了,一个陌生的男子走进了我们的家,我们家终于有了一个顶天立地的大男人,从此他带着我们一家人——我的母亲,奶奶,姐姐、弟弟和我,向前奔日子。  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

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
