粘土矿物去除赤潮生物的动力学研究

于１９９２年４－９月进行粘土矿的絮凝赤潮生物（微型原甲藻）的动力学研究；考察粘土种类、浓度、第二组分（ＰＡＣＳ）和ＰＨ等因素对絮凝速率的影响，建立粘土矿物絮凝赤潮生物的动力学模型，从理论上分析和讨论各种因素的影响，并提出提高絮凝速率的方法和途径。结果表明，高岭土体系絮凝速率大于蒙脱土体系，其速率方程可用双分子反应来描述。其中，速率常数随絮凝过程发生变化；粒子间的相互作用能和作用半径是控制和影响絮凝

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.     

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％。
