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.

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。
