台风预报系统

本文介绍的是一项在微机上实现的台风预报专家系统。该系统可进行台风气候查询、台风路径检索、台风特例查询，并能利用相似加权法制作出１２－７２小时台风路径和中心强度预报，对异常路径台风也可提供一定的诊断预报判据。本系统已在军内外一些气象业务单位得到应用，实践证明它是一种简便有效的台风预报工具。     

Diet analysis of Antarctic krill Euphausia superba Dana

Sampling date and position are shown in Table 1.Complete E.superbasamples with fullstomach were usua1ly used.They were averagely 45 mm long and 1.5 g weight(wet).Beingconcentrated with filtered sea water,every food species from krill stomach was observed andidentified under an optical microscope,and their size was measured.

冲绳海槽天然气水合物BSR的地震研究

根据多道地震反射资料分析,在冲绳海槽南部和中部发现了拟海底反射层(BSR)现象。通过对海底异常反射层的振幅特征、速度异常和AVO属性分析,说明该BSR可能反映了天然气水合物的存在,并发现冲绳海槽断层与天然气水合物的形成有密切关系。

近1300年来古胶州港位置的变迁

本文主要依据有关方志、文史资料，着重考证了近１３００年来古胶州港位置的变迁，研究发现，古胶州港的位置自唐代至清末近１３００年间，沿胶州湾西、北岸大致经历了７次变更，特别自明代开始，港口位置变迁尤为频繁，作者初步分析认为这与历史时期胶州湾内西、北岸的不断淤涨和胶莱南河、大沽河口的冲淤作用有关。     

Chemistry of marine resources-ⅩⅨ. The molecule design and synthesis of crow-link type alkyd resin and its enrichment behaviour for potassium ion in sea water

This paper first presents the molecule design and synthesis of crown-link type alkyd resin,and its enrichment behaviour for potassium ion in low concentration solution and sea water.On the basis of some theory concepts of Host-Guest chemistry developed in recent years,we have designed and synthesized a new polymer enrichment agent of crow-link resin for potassiumion,i.e.,polymacrocyclic ether bislactone of diethylene glycolpyromyllitic acid(briefly called crown-link type alkyd resin or PBL resin).The yield was about 97.4%,almost quantitatively.     

冰层厚度传感器及其检测方法

水结冰和冰融化过程中的电阻、电容、温度物理参数与被检测冰表面以上的空气层或冰下水层的电阻、电容、温度有一定的差异,有些差异在数值上比较明显。基于这一特点,笔者提出了利用空气、冰与水的物理特性差异实现对冰层厚度及冰下水位接触式检测的新思路,对含有导电杂质的冰、冰-水混合物、水、空气的电阻、电容特性随温度的变化规律进行了初步分析,并得到冰的弱导电性质和冰与水的电容区间单调特性,据此提出了冰层厚度传感器结构及其冰厚检测原理,介绍了新型冰层厚度传感器在实践中的应用。     

基于投影网格的大面积水面生成算法

本文主要研究在现代硬件条件下,如何为渲染生成一个大面积的水面。为了达到摄像机高低不同时对分辨率的要求,同时保持空间的可量测性,现在经常使用的生成算法是各种"层次细节"的方法。但层次细节也存在存储数据量大以及接边等问题。本文介绍了一种替代的算法:投影网格算法。投影网格从我们希望在投影后得到的网格入手,反向找出网格在投影前的位置,更有目的性,有自己的优势。     

Tephra Discovered in High Resolution Peat Sediment and Its Indication to Climatic Event

Floating tephra was deposited together with ice core,snow layer,abyssal sediment,lake sediments,and other geological records.It is of great significance to interpret the impact on the climate change of volcanic eruptions from these geological records.It is the first time that volcanic glass was discovered from the peat of Jinchuan(金川)Maar,Jilin(吉林)Province,China.And it is in situ sediments from a near-source explosive eruption according to particle size analysis and identification results.The tephra were neither from Tianchi(天池)volcano eruptions,Changbai(长白)Mountain,nor from Jinlongdingzi(金龙顶子)volcano about 1 600 aBP eruption,but maybe from an unknown eruption of Longgang(龙岗)volcano group according to their geochemistry and distribution.Geochemical characters of the tephra are similar to those of Jingiongdingzi,which are poor in s.Jica,deficient in alkali,Na20 content is more than K20 content,and are similar to distribution patterns of REE and incompatible elements,which helps to speculate that they originated from the same mantle magma with rare condemnation,and from basaltic explosive eruption of Longgang volcano group.The tephra,from peat with age proved that the eruption possibly happened in 15 BC-26 AD,is one of Longgang volcano group eruption that was not recorded and is earlier than that of Jinglongdingzi about 1 600 aBP eruption.And the sedimentary time of tephra is during the period of low temperature alteration.which may be the influence of eruption toward the local climate according to the correlativity of eruption to local temperature curve of peat cellulose oxygen isotope.
