NUMERICAL EXPERIMENTS OF WINDS OVER THE NORTHERN PACIFIC OCEAN WITH NONLINEAR DIAGNOSTIC DYNAMIC MODEL

By means of the proposed nonlinear diagnostic dynamic model for the planetary boundary layer (PBL) wind field, an introduction is given to the MOD method for wind prediction. Based on the MOD experiments on the surface wind field over the Northern Pacific Ocean from April to October 1985, it is concluded that the nonlinear diagnostic dynamic model used is better than the linear one.     

口虾蛄(Oratosquilla oratoria)同工酶的组织特异性及生化遗传分析

采用聚丙烯酰胺凝胶垂直平板电泳方法，研究分析了口虾蛄(Oratosquilla oratoria)肌肉、眼球、腹鳃、心脏和肝胰腺5种器官或组织中LDH、ADH、MDH、SDH、MEP、POD、AMY、GDH、SCD、EST、GLDH和SOD共12种同工酶的表达情况。结果表明，口虾蛄同工酶的表达具有明显的组织特异性。对12种同工酶进行生化遗传分析，获得了基本酶谱。12种同工酶共记录出35个基因座位，其中11个基因座位Ldh-3、Adh-1、Sdh-2、Est-1、Est-2、Est-3、Mdh、Mep-7、Gldh-1、Gldh-2和Scd-1为多态，其多态座位比例为31.43％。

海湾扇贝养殖群体遗传多样性的研究

用等位基因酶的聚丙烯酰胺凝胶电泳技术,研究了大连沿岸不同生态环境条件下的大李家湾低排筏、大李家湾高排筏、凌水桥、棋盘磨4个海湾扇贝养殖群体的遗传多样性.在4个群体的7种等位基因酶和闭壳肌蛋白中均检测到了22个基因位点,各群体的多态位点比例分别为22.73%,22.73%,22.73%,18.18%(P≤0.95)和27.27%,27.27%,31.82%,36.36%(P≤0.99);杂合度观测值分别为0.064,0.071,0.075,0.069;Hardy-Weinberg平衡偏离指数分别为-0.068,-0.020,-0.032,-0.050;近交系数分别为0.568,0.565,0.487,0.550;位点等位基因有效数分别为1.102,1.109,1.143,1.122;遗传变异综合评价指数分别为0.0060,0.0071,0.0088,0.0073.海湾扇贝养殖群体遗传多样性总体水平较低,但在这4个群体中,凌水桥群体的遗传多样性水平最高,大李家湾高排筏和棋盘磨群体的遗传多样性水平较高,大李家湾低排筏群体遗传多样性水平最低.     

AHP RESIN AND ITS URANIUM ADSORPTION MECHANISM

I. INTRODUCTION AHP resin is a new type of adsorbent and has been studied by the units concernedfor several years. There is little report about this work so far. AHP resin was synthesizedin aqueous phase with tetra-ethylene pentamine (TEPA), epichlorohydrin (ECH) andC-reagent as raw materials, and basic zinc carbonate (P_Z_n) and rubber solvent oil (120Gasoline) as pore-forming material. Compared with the technique of the amorphous lumpresin and that of the resin synthesized in oil phase, the new technique of resin synthesizedin aqueous phase manifests many advantages, such as raising the capacity of uranium-adsorption of the resin, simplifying the after-treatment process, reducing the cost, etc. Sea water, in which all kinds of cation and anion exist, is a system of electrolytes,and the concentrations of many ions are higher than the concentration of uranium for     

A COMPARATIVE STUDY OF 1982-1983 EL NIÑO EVENT

The 1982-1983 El Niño event is examined in comparison with the other El Niño events in 1949-1983. The relationships of subtropical high to the sea surface temperature (SST) show the important influence of the atter, which vaired with the characters of El Niño events.     

头足类视觉特性的电生理研究 Ⅰ.无针乌贼视网膜电图的特性

乌贼是重要的海洋水产资源之一,对其视觉特性的研究在理论上和实践上显然都有一定的意义。视网膜电图(ERG)作为网膜的综合电活动是反映视觉特性的一个良好指标。乌贼的ERG的特性至今缺乏系统的研究。本文对其ERG的波形和适应特性作了较详细的描述。续文将报导对ERG的光谱敏感性的分析。
