用实测波浪数据确定JONSWAP谱参数

本文给出应用实测波浪数据确定JONSWAP谱参数的方法，若Hs,Tz,Tc分别为实的有效波高，平均上跨零线周期，平均峰－峰周期并令y=Tz/Tc，本文导出求解谱参数γ值的方程f（γ，y）＝0。根据这个方程的解并应用最小二乘法，γ作为y的函数的表达式可写为（对于2.54≤γ≤15.34及1.6≤y≤1.79）。     

Th-and U-bearing minerals in the SE Mediterranean margin of Spain

This paper presents the first specific study of the Th-and U-bearing minerals, which were recently found in the SE Mediterranean margin of Spain (El Hoyazo area,Almeria province). These minerals are REE phosphates (mainly monazite) which occur as amoeboidal-to-elongate inclusions,from around 10 120μm to 120μm, hosted in single garnet crystals from dacite lavas and metamorphic rocks from the El Hoyazo Volcanic Complex. Th and U contents are higher than 1 wt%, with 3.04 to 5.62wt% for Th02, and 0.7 to 1.75 wt% for UO2. Both elements are also found in xenotime (ThO2:0.24,UO2:0.27wt%). Given that the erosion of the volcanic source rocks has generated a “placer-type” deposit of monazite sands and that garnets (main carriers of monazite) are being commercialised, an environmental monitoring and management plan should be urgently executed in the area.     

分子云ORION—IL的CH3CN Jk=6k—5k谱线的观测

使用名古屋大学４米毫米波射电望远镜于１９９５年１月对对分子云ＯＲＩＯＮ－ＩＬ区域的ＣＨ３ＣＮＪｋ＝６ｋ－５ｋ谱线进行了观测，得到了该区域的５点的谱线。该谱线的观测为青海站１３．７米毫米波射电望远镜提供了又一条可供观测的分子谱线。

河南地调健儿在西藏找到大型铜铅锌矿床

河南地调健儿克服了高寒缺氧,交通、通讯不便,供给不足等诸多困难,以科学求实的态度和拼搏奉献的精神,在青藏铁路沿线南段为国家找到铜铅锌矿产地4处,其中大型2处,中型、小型各1处。向国家提交铜资源量36万余吨,铅锌资源量240余万吨,银近千吨,金10余吨。这一信息是由日前召开的《西藏当雄县拉屋-嘉黎县同德一带铜铅锌多金属矿评价报告》评审验收会议上获悉的。 西藏雅鲁藏布江成矿区战略性矿产勘查,是“十五”期间国家地质工作矿产资源调查评价部署的4个重点之一。河南省地质调查院以其雄厚的技术实力和十余年西藏地质矿产勘查工作积累的…     

Characters of the Pco2 and CO2 Flux in the East China Sea in Autumn

Pco2 of air and seawater samples from the East China Sea(ECS) were measured in situ in autumn, 1994,Ocean currents,terrestrial fluviation,biological activities,etc.,Pco2 char-acters in air and seawater were investigated,CO2 flux and its character in the East China Sea are discussed on the basis of the Pco2 profiles of air and seawater,It was clear that the nearshore was the source of CO2;and tht the oulter sea area was the sink of CO2; and that the shelf area of the EXS is a net sink for atmospheric CO2 in autumn.
