浅谈涉外海事仲裁协议的认定

仲裁亦称公断，是指争议的当事人在自愿的基础上，将争议提交非司法机构的第三者审理，并做出对争议各方有约束力裁决的一种解决争议的法律制度。以私法方面带有国际因素或涉外因素的争议为对象进行的仲裁，通常称为国际商事仲裁。其在狭义上不同于解决国家之间某一公法上的争端的国际仲裁、不同于为解决国家与企业或私人实体间争议所进行的跨国仲裁、也不同于解决一国范围内自然人、法人和其他组织之间争议包括行政仲裁在内的国内仲裁：广义上国际商事仲裁还包括跨国仲裁。国际商事仲裁主要包括国际贸易和国际海事仲裁。本文仅在狭义上讨论。按照我国现行法律规定，本文称涉外海事仲裁。     

Random wave-current interactions in water of varying depth

Refraction of incoherent random gravity waves with currents and bottom topography results in spatial variations in the spectral characteristics of the free surface. Prediction of such variations based on the radiation transfer equation is in a simple analytic form for the case of one dimensional inhomogeneities in currents and topography. This analytic form is examined in terms of two-dimensional wave number- and polar frequency-direction spectra along the associated dynamic and kinematic constraints relevant to wave breaking and reflection. Results are specialized to the simplest case of horizontal shear currents in deep and shallow water with explicit examples to illustrate the relative and combined effects of currents and topography on free surface spectra.     

龙须菜和扁江篱多糖的组成及其抗肿瘤效果

于１９８５－１９８７年期间用冷水和热水对采集于青岛的龙须菜和扁江篱的琼胶型多糖进行提取。两海藻的热水提取多糖都通过ＤＥＡＥ－ＳｅｐｈａｄｅｘＡ５０色谱桩用热水和不同浓度ＮａＣｌ深液前后进行洗脱分级。龙须菜和扁江篱多糖的主要级分分别为０．５ｍｏｌ／Ｌ和１．０ｍｏｌ／ＬＮａＣｌ洗脱级分。对各级分做化学分析及ＩＲ和＾１３ＣＮＭＲ光谱分析。结果表明，龙须菜多糖由琼二糖、琼胶糖前体和６－ＯＣＨ３－琼二糖组成

喀斯特荒漠化是一种地质—生态灾难

ＫＤＮ是一种ＧＥＯＬ－ＥＣＯＬ灾难,是发生潮湿的碳酸盐岩区的土壤侵蚀、土地退化与生态系统凋萎,致使人类很难生活在其中。ＫＤＮ是我国四大ＧＥＯＬ－ＥＣＯＬ灾害中最难整治、最难摆脱贫困的地区。本文按国际公认的原则为准,认定“石山化”≠ＫＤＮ,从地质结构性气候、物候和生态系统多因子厘定了ＫＤＮ术语,认定人为扰动与人口超载是其产生的序参量。其过程最迟也是３００多年前明清朝代屯垦开始,近半个世纪加速衰竭,森     

灵山岛浅海岩礁区底栖生物的群落特点

浅海岩礁环境系高生产力区,在中、高纬度海域中,由大型海藻和大叶藻(Zosteramarina)所构成的初级生产力常为浮游植物初级生产力的数倍(Miller et al.,1971)。同时,此种环境又是以大型藻类或有机碎屑为食物的珍贵海产品鲍鱼(Haliotis)、刺参(Stichopus)、海胆(Strongylocentrotus)等的栖息场所和采捕作业区;还是一些优质鱼类星鳗( Astroconger myriaster)、鲈(Lateolobrax japonicus)等的藏匿场所和游钓渔业的渔场;重要经济藻类石花菜(Gelidium)等也在此环境中定着、生长。所以,浅海岩礁的资源开发前景很好。为了促进上述珍贵海产品的增、养殖生产和发展游钓渔业,有必要对浅海岩礁底栖生物群落的结构、功能进行系统研究,以便为岩礁区的资源开发和海岸带环境保护提供科学依据。为此,中科院海洋研究所在1987年初步调查的基础上,1992年以灵山岛为点,对水下岩礁环境和生物群落进行了系统的调查。本文主要分析浅海岩礁底栖生物的群落特点。     

Identification of Pb sources in Yellow Sea sediments using stable Pb isotope ratios

Rapid economic developments in East Asian countries have inevitably resulted in environmental degradation in the surrounding seas, and concern for both the environment and protection from pollutants is increasing. Identification of sources of contaminants is essential to environmental pollution management. In this study, the provenance of anthropogenic lead (Pb), a major pollutant of Yellow Sea sediments, was determined for river mouth sediments, including those of the Changjiang, Huanghe, Han, and Geum Rivers, and for age-determined shelf core sediments through the measurement of Pb isotope ratios in the HCl-leached fraction using multi-collector inductively coupled plasma-mass spectrometry (MC ICP/MS). Anthropogenic Pb has accumulated in shelf core sediments since 1910, and its isotope ratios were estimated as 0.863–0.866 and 2.119–2.125 for ²⁰⁷Pb/²⁰⁶Pb and ²⁰⁸Pb/²⁰⁶Pb, respectively, from the mixing relationships of the two endmembers. River mouth sediments exhibited enough distinction in anthropogenic Pb isotope ratios to be discriminated: 0.874 (2.144) in the Huanghe, 0.856 (2.129) in the Han, 0.857 (2.122) in the Geum, and 0.854 (2.101) in the Changjiang for ²⁰⁷Pb/²⁰⁶Pb (²⁰⁸Pb/²⁰⁶Pb), respectively. Although isotope ratios of geogenic Pb in sediments dating before 1910 showed narrow ranges (0.842–0.845 and 2.088–2.100 for ²⁰⁷Pb/²⁰⁶Pb and ²⁰⁸Pb/²⁰⁶Pb, respectively), distinct isotope ratios in each core permitted source identification of sediments in the Yellow Sea based on geographic locations and the geogenic Pb of each river. By comparing the isotope ratios of the estimated anthropogenic Pb to source-related materials, the provenances of anthropogenic Pb in Chinese river sediments were presumed to be Chinese coal or ore, which is also a major source of atmospheric particulate Pb. The anthropogenic Pb in the shelf core sediments in the northern Yellow Sea originated from northern Chinese cities such as Beijing and Tianjin through atmospheric pathways. Pb isotope ratios indicated that Pb in Korean river sediments was characteristic of local Korean ores.     

Determination of palladium and platinum in seaweed

Palladium and platinum concentrations were determined for twenty two species of seaweed from the California coast, U.S.A.. A new sensitive analytical technique using atomic absorption spectrometry was developed for palladium in seaweed. For the first time, palladium contents in seaweed were obtained. The contents of palladium and platinum varied from 0.09 to 0.61 ng g^–1 and 0.25 to 1.75 ng g^–1 in dried material, respectively.The average ratio of Pt/Pd found in seaweed was 3.5, while the ratio of Pt/Pd was 4.5 in seawater. Therefore, it is postulated that there is no discrimination for seaweed to accumulate palladium and platinum from the ambient seawater due to the chemical similarity of the metals.     

黄、东海近海面空气湿度分析及估算

利用1974～1982年黄、东海海洋水文气象标准断面实测资料对近海面空气湿度的分布、变化进行了分析。讨论了冬、夏季海、气温与湿度的关系,并对冬、夏季近海面空气湿度进行了估算。结果表明,夏季,空气湿度为气温的函数;冬季,除了考虑空气本身平流的水汽外,还必须考虑海洋向大气的水汽输送。     

长江口海水的密度

为了核对1980年国际海水状态方程应用于中国近岸海水的可靠性,高精度的磁力浮沉子密度计在15—25℃,盐度5—35,一个大气压条件下,测量了长江口附近海水及其人工稀释海水的相对密度。结果表明,海水密度直接测量值系统地偏高于状态方程计算值,二者之间的偏差随水样盐度值降低而增大,且与海水[Ca~(2+))/s比值成明显正相关关系。经计算机拟合,导出了长江口附近海水及其稀释海水的状态方程,该方程计算值与实验值的平均标准偏差为±3.9×10~(-3)kg/m~3。
