从政治参与的角度考察我国坚持陪审制度的现实性

陪审制度的本质是一种重要的民主政治的政治思想和司法功能的体现,陪审制度的确立和完善,是人类走向民主文明的司法形式之一。本文认为重新认识陪审制度的价值双重性,彰显陪审制度的政治价值与司法价值,在推进公众政治参与需求下,完善我国的人民陪审制,已然成为法学理论界及司法实务界应重新认识的重要课题

Distribution of anaerobic bacteria in surface sediments from the Western Arctic Sea

用逐步稀释法在4℃和25℃培养条件下测定了西北冰洋海域24个表层沉积物样品中厌氧菌(AnAErObIC bACTErIA,AAb)的检出率和含量.同时,分析了这两项指标的水平分布(纬度间、经度间)差异,以及在不同水深的变化特征.结果表明,在4℃和25℃培养条件下厌氧菌检出率高达100%,AAb含量范围分别为9.00x102~2.40x107CEll·g-1和2.90x104~2.40x107CEll·g-1,平均含量分别为4.54x106CEll·g-1和3.99x106CEll·g-1.AAb含量存在水平分布差异,随着纬度升高,或经度自西向东,或水深的加大,AAb的含量均呈现逐渐降低的趋势.The occurrence and content of anaerobic bacteria in 24 surface sediments in the Western Arctic Ocean were measured via progressive dilution under laboratory incubation at 4℃ and 25℃,and the spatial patterns of anaerobic bacteria distribution were further examined.All the samples have anaerobic bacteria.The contents of anaerobic bacteria cultivated ranged from 9.00×102 to 2.40×107 cell· g-1 wet sample (the same hereafter) and 2.90×104 to 2.40×107 cell· g-1 with an average of 4.54×106 cell· g-1 and 3.99×106 cell· g-1 in the 4℃ and 25℃ samples,respectively.The distributions of anaerobic bacteria varied by both latitude and longitude,and also in sediment samples with different water depths.The anaerobic bacteria content decreased from low latitude to high latitude,from the western area to the eastern area,and from shallow water to deep basin.国家自然科学基金(No.40576060;40376017)---

Investigation of the origin and evolution of groundwater in Yang-Dai River Plain by chlorine,oxygen 18 and deuterium

通过分析地表水和地下水中氯离子浓度和δd、δ18O值的空间分布特征,揭示了秦皇岛洋戴河平原地下水的形成演化规律.结果发现,洋戴河平原地表河水来源于中上游水库水和大气降水的混合,且河水沿程受到δd、δ18O值、氯离子浓度更低的支流或灌渠水补给,从而使δd、δ18O值、氯离子浓度呈现沿程逐渐降低的现象.山前丘陵区地下水主要接受大气降水的直接补给,洪积扇及山麓地带地下水受到了一定的蒸发作用影响,除了接受丘陵区地下水的侧向补给外,洋河附近地下水还受到洋河水库水的混合.研究区西部咸水带的地下水由上游地下水和大泥河地热咸水混合而成,地热咸水的混合比率约为13%,而东部咸水带的地下水由上游地下水、本地污水和地热咸水混合而成,地热咸水的混合比率不超过9%.在海水入侵区,地下水主要由本区地下淡水和海水(海水混合比率不超过10%)混合而成,并且受到了不同程度的地表水或农田灌溉水的补给,其中,浦河一带是地表水或灌溉水补给较为明显的地段.The aim of this paper is to reveal the origin and evolution of surface water and groundwater by analyzing the spatial distribution of chloride ion concentration and δD and δ18O values in surface water and groundwater in Yang-Dai River Plain.The Yang-Dai River originates from the mixing of water of reservoir and meteoric water,and river water is also from the recharge in the tributary and irrigation ditch which have much lower chloride ion concentration and δD and δ18O values.Therefore,chloride ion concentration and δD and δ18O values in river water decreases gradually from upstream to downstream.The groundwater in hilly area is primarily recharged by meteoric water,and the groundwater in pluvial fan and piedmont experiences evaporation partly.The groundwater in pluvial fan and piedmont is recharged not only laterally by upstream groundwater from mountainous and hilly area,but also by Yang River reservoir water.In the study area,the groundwater in the west part of salty water region is mixed between upstream groundwater and salty geothermal water originated from Danihe area,with a mixing radio of 13% salty geothermal water.In comparison,the groundwater in the east part of salty water region is mixed by upstream groundwater,sewage water and salty geothermal water,with a mixing radio of up to 9% salty geothermal water.In the seawater intrusion region,the groundwater was mainly constituted of local fresh groundwater and intrusive seawater with a mixing ratio of up to 10% seawater,and is also partly recharged by surface water and agricultural irrigation water which have higher contribution to the groundwater recharge in Pu River area.国家重点基础研究发展计划(973)项目(No.2010CB428805); 环保公益性行业科研专项经费项目(No.201309006)~

简要回顾了海底热水矿床的研究简史,根据我国的国情,将海底热水矿床从研究到开采划分为5个阶段。根据全球同类矿产资源勘探开采形势,结合我国的特点,建议尽早将工作重点从勘探期转移到圈矿阶段,寻找资源量大,开采成本低,回报率高的海底热水矿床,并向国际海底管理局申报,同时建议积极研发海底热水矿床的圈矿与开采技术。A brief review is made on the history of submarine hydrothermal deposits researches in China.The history could be divided into five stages.Take into consideration the global exploration and exploitation activities of relevant mineral resources,we suggest that China should select some parts of international seabed with large reserve of submarine hydrothermal deposits,low mining cost and high return on the basis of the survey data in hands and make application for mining privilege from the International Seabed authority as early as possible.Meantime,China should concentrate its survey cruises more on enclosure of rich areas,and at the same time,invest more on development of mining technology as preparation for future exploitation of the resources.九五中国大洋矿产资源开发研究项目(DY95-05-10);国家自然科学基金(49873015

Overall Planning and All-Round Consideration to Construct a Competitive Marine Fishery Industry in Fujian

海洋渔业是我国稳步发展的海洋产业,其不仅能提供充足的优质蛋白,也可为海洋生物医药及生物制品生产提供原料,还能带动渔港建设、渔船修造、渔具生产、水产品加工、贸易等行业发展,对旅游品市场及滨海旅游业也有积极影响,可对相关产业的发展起到促进作用。福建省具有全国约五分之一的海岸线,海域面积比陆域面积大12%,具有发展海洋渔业所需的优越条件和产业基础。针对福建海洋渔业目前面临的问题,综合考虑各方因素,提出了以海洋生物资源的保护、开发利用为主线,进行产业链的规划设计,打造福建海洋渔业品牌,做大做强海洋渔业。Marine fishery is a steadily growing marine industry in China.It provides not only sufficient high quality protein,but also raw materials for marine bio-pharmaceutical and biological products.The development of marine fishery will stimulate the construction of port,repairing and building of fishing boats,Production of fishing gear,processing of aquatic products and trade.Moreover,it will bring positive effect to the market,tourism and other related industries.Fujian province has great advantages and industrial basis for the marine fishery development.It has a long coastline(about one-fifth of the national coast-line) and a large sea area(12% larger than the land area).With overall consideration to the current problems in marine fishery,we proposed to reinforce marine biological resources protection, development and utilization, as well as to design an industrial chain in order to build the brand of Fujian marine fishery and bring a brighter and more prospective future.福建省科协决策咨询和调查研究重点课题“福建省海洋经济发展布局研究”(A1209

Distribution of Anaerobic Bacteria in Sedimentary Cores From the Arctic Ocean

用逐步稀释法对北冰洋研究区10个沉积物岩芯(计189份样品)的厌氧细菌(AAb)进行分析,用改进的zObEll 2216号培养基,在4℃和25℃温度中分别培养3周以上,根据培养结果统计样品中厌氧细菌的检出率与含量,分析厌氧细菌含量的分布情况。结果表明,4℃时AAb检出率为85.71%,含量范围0--2.40x109个.g-1,平均4.42x107个.g-1;25℃时检出率为93.05%,含量范围0--1.10x109个.g-1,平均5.31x107个.g-1,略高于4℃时的平均值。研究表明研究区岩芯中广布AAb;温度的提高,可能提高AAb的相关指标;沉积物深度增加可能有利于AAb生长,但太深也不利于AAb生长,呈中层增高现象,但并不规则;在一定水深范围内,水深增加也有利于AAb的生长。同时给出了研究区内不同海域AAb分布差异。189 samples divided from 10 sedimentary cores collected in the studied area of the Arctic Ocean are analyzed for anaerobic bacteria(abr.AAB) detection by means of the step-by-step dilution method.The samples respectively with the 4 ℃ temperature and the 25 ℃ have been cultured for 3 weeks to determine the AAB-detected rate and the content in the samples and to analyze the AAB distribution.As it is shown from the results,the AAB-detected rate of the 4 ℃ samples is 85.71% and the AAB contents range between 0 and 2.40×109 ind./g with an average of 4.42×107 ind./g,and the rate of the 25 ℃ is 93.05% and the contents range between 0 and 1.10 ind./g with their average of 5.31×107 ind./g,slightly higher than the 4 ℃ average.Therefore AAB is widely distributed in the cores from the studied area.It seems that the temperature increment is helpful for the increments of those indices.In addition,the sedimentary depths within the centain limit might be favourable to AAB growth.In general,the AAB contents become higher in the middle layers although it is not definitely regular.Water depth within a certain limit in the ocean might be also advantageous to AAB growth.The difference among the AAB regional distributions in the studied area is shown in the paper.国家自然科学基金——楚科奇海及其邻近海域沉积物中细菌生物地球化学(40576060);楚科奇海沉积物中古环境变化的地球化学响应基金(40376017
