前颌间银鱼资源变动原因的初步探讨

于1985—1988年对前额间银鱼生物学特性、资源变动状况及其原因进行了现场和社会调查。调查表明,前颌间银鱼资源变动的原因是南、西区和吴淞口三大污染源对其生态环境严重污染;同时还有多年持续过捕超过其再增殖能力。为此,提出治理污染,恢复前颌间银鱼的生活环境及保护繁殖亲体的对策和建议。

中国海岸风成沙ESR测年的研究

介绍ＥＳＲ测年的基本原理，并讨论风成沙Ｇｅ心测年的可行性、风成沙Ｅ＇心的特征、测年误差及可靠性等问题。１９９２－１９９３年在渤、黄、东、南海沿岸采集的１００余个风成沙样品ＥＳＲ测年实验表明，绝大部分海岸风成沙的年龄为１－７万年。     

Combined refraction and diffraction models for sea waves over complicated topography and with currents in shallow water

-Combined refraction and diffraction models in the form of linear parabolic approximation are derived through smallparameter method. More strictly theoretical basis and more accuracy in the models than Lozano's (1980) are obtained. Some theoretical defects in Liu's model (1985) with consideration of current are not only found but also eliminated. More strict and accurate models are, therefore, presented in this paper.The calculation results and analysis in applying the models to actual wave field with consideration of bottom friction will be given in the following paper.

闽江口水动力和污染扩散数值模拟

本文建立了闽江口二维水动力、污染扩散数值模型，模型采用ＡＤＩ双向隐式求解。在水动力模拟中，对岸界的丁坝有用线性边界进行拟合，并考虑到河口区侧向摩擦作用；在污染扩散模拟中，用动态拟合的方法对浓度水边界进行了较为合理的改进。计算结果表明，本模型是成功的。     

Analyses of the tidal data of 19 years

In this paper, tidal data of 19 years were analysed to obtain the harmonic constants of 472 constituents; yearly variations of the harmonic constants of some constituents for 19 years were also examined.We have also derived the formulae of response analysis by using another approach, and calculated 161 response weights of astronomical tides, solar radiational tides and nonlinear tides for 10 stations. Some significant results were obtained.     

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％。
