根据风速的统计分布，给出了有因次风速熵和无因次风速熵的定义及其计算方法，使用ＧＥＯＳＡＴ高度计１９８６年１１月－１９８９年２月的有效波高和风速的资料，计算，分析了南海海域上的波高熵，风速熵，给出它们的时间变化特征和空间变化特征，并对不同随机量的无因次熵，即随机度进行了比较。     

烟台套子湾八角深水港的开发研究

通过调查和比较，认为在我国渤海和北黄海南岸的套子湾八角海区是一个条件优越的深水港址，在阐述开发八角深水港的重要意义同时，根据城市布局规划和岸线及水域资源，参照国际港口未来发展趋势，结合我国对中、西部地区经济发展战略，对八角深水港的开发和布局进行了研究，为烟台市发展成为“现代化、国际型港口城市”，提出了港区未来建设的模式。     

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.     

宿松茅口阶沉积成岩研究

宿松地区茅口阶为一连续的海退沉积序列，先后发育浅海陆棚相、开阔台地相、颗粒滩相。所经历的成岩作用主要有胶结、重结晶、白云石化、压溶、溶蚀及充填等．本文还对成岩环境进行了讨论。

黑龙江省东部跃进山群中绿片岩的地球化学特征及地质意义

跃进山群出露位于佳木斯地块和那丹哈达地体之间，是完达山造山带的组成部分。它由大陆斜坡相沉积物、大洋中脊型玄武岩和洋岛型玄武岩组成，其中有镁铁－超镁铁质岩块体。它不是一个地层单位，而是与活动大陆边缘板块俯冲作用有关的蛇绿混杂岩     

铝对铬成矿地球化学的依存性和对抗性

基于岩浆铬矿床与超镁铁质岩石的关系，从元素亲合性和共生规律的角度揭示了铝对铬成矿制约的主导作用，分析了铝和铬亲石、亲氧的二重性及其晶体化学的依存关系。论证了超镁铁Ｓｉ－Ｏ体系中铝丰度过高或过低均不利于铬的成矿。揭示了制约元素分散富集的因素都是在一定条件下互为依存和转化的，是在动态中的矛盾的对立和统一。
