随机海浪的列率谱分析研究

首次将列率谱分析的方法引入到随机海浪的研究。根据不同环境条件下实验室资料，对列率谱与频率谱进行了比较。结果表明，列率频对频率谱高频部分有明显改善，特别对二倍频含能段的分辨具有明显的优越性。另外，列率谱具有计算速度快、简单易行、分辨率高等优点。     

烟威渔场盐度预报及分析

本文以我国北黄海的烟威渔场为研究对象,采用优选因子场预报模式,对盐度的时空变化进行预报试验。文中对所采用的统计预报方法,作了简要介绍。对影响本海区盐度变化的显著因子及预报结果作了初步分析。预报试验表明:预报的总体平均绝对误差为0.27‰,预报相对误差在18％左右,预报误差小于0.5‰的站数占总站数的85％,预报趋势与实测资料基本一致。

CASE ANALYSIS OF SEA LEVEL CIRCULATION FOR THE ATMOSPHERE OF LOW LATITUDES IN MID-SUMMER

In the light of the sea level synoptic charts from July to August for 1975-1978, we obtained more observed records of low latitudes by using the analysed stream and temperature-moisture field (or so called energy field θe field and θse field), the main characteristics of these fields in the period of multi-typhoon genesis and of typhoon interval in the mid-summer are studied.Finally, it should be pointed out that the position of the typhoon genesis and the typhoon track are generally consistent with the low temperature-moisture region of the sea surface as well as with its tendency, so that a valuable information is obtained for the forecast of the typhoon track.     

GEOCHEMICAL CHARACTERISTICS OF INTERSTITIAL WATER OF THE BOHAI GULF

This paper discusses the geochemical characteristics of the interstitial water of the Bohai Gulf, where the main salt contents (K+, Na+, Ca++ Mg+ + , C1-, HCO3-, SO4-) in 55 sedimentary layers of 13 cores (3-4 m in length) and those of bottom seawater have been determined and the exchange capacity and exchange cations (K+, Na+, Ca++, Mg++) of the layers analysed (see Fig. 1)Fig. J. The stations of core samplings in the Bohai Gult.     

AN ECOLOGICAL STUDY OF BENTHIC ORGANISMS IN THE NEARSHORE WATERS TO THE WEST OF TAIWAN STRAIT

In seven cruises on benthic organisms in the nearshore waters(>50 m) to the west of the Taiwan Strait(23°20''-25°54''N,117°11''-119°58''E) in 1961-1964,altogether 189 stations of quantitative grabbing and 33 stations of qualitative trawling were made.
Altogether 392 species of benthic organisms have been identified.The composition was dominated by nearshore shallow water species,with tropical and subtropical species absolutely dominant.The total average of biomass was 38.0 g/m² and average density,116.0 ind./m².The communities of benthic organisms in the area can be classified into five communities namely,(1) Amphiura sp.-Acaudina molpadioides Community;(2) Protankyra asymmetrica-Arnphioplus pracstans-Murex trapa Community;(3) Modiolus meicalfei-Phyllophorus liuwutiensis-Armandia letocirris-Nephtys sinensis Community;(4) Branchiostoma belcheri-Solenr oseomaculatus-Marphysa sinensis- Onuphis eremita Community;(5) Iconomtra japonica-Barbatia decussata Community.     

中国湖泊近代沉积物的有机地球化学特征与油气关系

中国湖泊面积辽阔,资源丰富.研究湖泊近代沉积物的有机地球化学特征及其与油气关系,对陆相石油成因和油气资源开发,“将今论古”建立古地貌模式有着重要意义.为了探讨油气化探异常的形成机制和生油研究的有关理论,对中国第四纪不同类型的湖泊沉积物,进行了生油有机地球化学分析研究,取得了一些规律性的认识.     

渤海海洋油气资源开发利用与前景展望

在海洋经济产业构成中,海洋油气开发是新兴海洋产业。在渤海海洋经济构成中,海洋油气占渤海海洋经济比重的8.5%,占渤海新兴海洋产业构成的19.4%。渤海海洋油气资源的开发利用,不但能缓解我国油气安全问题,同时也为经济快速增长的渤海经济区的发展提供物质基础。一、渤海丰富的油气资源1. 油气资源总量渤海沉积盆地的生油凹陷面积大,有效勘探面积为5.3万km2,其中仅新生界生油岩层就厚达3 200 m,生油岩体约2.4万km3。2000年提出的预测资源量是97亿t。2. 已形成了油田产业群渤海在200万年以前,形成了蕴藏丰富油气资源的渤海沉积盆地。在渤海海…
