黑鲷早期鳞被的形成

黑鲷Sparus macrocephalus(Basilewsky)幼苗鳞被最早出现的部位是在躯干部胸鳍基后至肛门直上方的侧线处。黑鲷只具一个鳞被起始中心。最早出现鳞片的个体为体长9.5—14.1mm,平均11.51±0.85mm,全长11.2—16.5mm,平均13.65±1.01mm,孵后日龄23—35d。鳞被发育完全时的最小个体为体长12.1—18.5mm,平均14.57±1.55mm,全长14.8—23.5mm,平均17.99±2.17mm,孵后日龄27—42d。     

东海沉积物中轻矿物的研究

本文对东海大陆架、冲绳海槽及长江表层沉积物中的轻矿物进行了研究。调查区范围为121°-129°E,32°-26°30′N。长江采样区段为芜湖——长江口。共分析了124个样品,其中长江样品11个,东海大陆架样品100个,冲绳海槽样品13个。使用的样品粒级为0.1-0.25毫米。     

塞曼石墨炉原子吸收法直接测定海水中的铬

海水基体对Cr有增感作用。本文研究了抗坏血酸、柠檬酸三铵、酒石酸、乙酸铵等有机基体改进剂对消除基体干扰效果。前二者均有效地消除基体干扰,但1％抗坏血酸 1％柠檬酸三铵混合试剂的效果更好,它不仅可以消除基体干扰,还可降低背景及噪声,Cr的吸收峰也较平滑。本法准确,相对偏差在0.7—4.4％范围内。回收率在92—109％范围内。若海水Cr含量低于定量下限时,可采用多次进样法。     

A study on sample pretreatment of analysis of Cd, Pb and Zn in seawater by IDMS

Isotope dilution mass spectrometry (IDMS) and ultra-clean room approach are successfully used in the determination of Cd, Pb and Zn in seawater and the sample pretreatment of analysis. The precision in the determination of Cd, Pb and Zn in seawater is better than±3% and the limits of detection are 6×10-12, 6×10-11 and 2.4×10-10 respectively. The effects of sample pretreatment such as filtration and acidification on the results of determination of Cd- Pb and Zn in seawater are disscussed.     

青岛文昌鱼的生活史──年龄、生长和死亡研究

于１９８９年８月－１９９０年７月对青岛文昌鱼的生活史进行研究。结果表明：（１）青岛文昌鱼种群由４个齿组组成，它至少生产４ａ以上，甚至可达６ａ左右。（２）在Ⅰ、Ⅱ齿时生长较快，平均年生长１３－１５ｍｍ，Ⅲ龄后生长速度减慢，即使同一年龄组的文晶鱼，在不同季节其生长速度也不同。（３）在冬春采集的文昌鱼中Ⅲ龄组的峰值较小。（４）繁殖季节过后，老龄文昌鱼因衰老而死亡。
