辽宁沿海泥炭堆积与全新世海面变化

辽宁沿海分布有丰富的泥炭资源，主要为埋藏泥炭，属于低位型的草本泥炭。按其成因可分为泻湖型、河漫滩型和沟谷型泥炭三种类型。在整个全新世时期均有泥炭形成，可分为早、中、晚全新世三个发育期，中全新世是辽宁沿海泥炭发育的最盛时期；沉积速率为０．２５～１．１ｍｍ／ａ。全新世海侵，约在距今６０００～７０００ａ达到最大范围；近五千年来海面在下降过程中有波动和相对稳定时期。     

Sea surface temperature variations in the southwestern South China Sea over the past 160 ka

Sea surface temperatures (SSTs) in the southwestern South China Sea have been reconstructed for the past 160 ka using the Uk37 paleothermometer from the core MD01-2392. The temperature differences between glacial times (MISs 6 and 2) and interglacial times (MISs 5.5 and 1) are 2.2~2.5 ℃. Younger Dryas event during the last deglaciation was documented in both the planktonic foraminiferal δ18O and SST records. After MIS 5.5, SSTs displayed a progressive cooling from 28.6 to 24.5 ℃, culminating at the LGM. During this gradual cooling period, warm events such as MISs 5.3, 5.1 and 3 were also clearly documented. By comparison of SST between the study core and Core 17954, a pattern of low or no meridional SST gradients during the interglacial periods and high meridional SST gradients during the glacial periods was exhibited. This pattern indicates the much stronger East Asian winter monsoon at the glacial than at the interglacial periods. Spectral analysis gives two prominent cycles: 41 and 23 ka, with the former more pronounced, suggesting that SSTs in the southern SCS varied in concert with high-latitude processes through the connection of East Asian winter monsoon.

可见光波段海面目标物的光谱对比度：I.理论基础

对海面目标物的目标观察，其能见距离与观测方向，海面背景光谱辐射，目标物固有光谱辐射和大气分子及气溶胶的光学参数等因素有密切关系，本文从理论上分析各种因素的影响，特别是研究了海面背景辐射目标物光谱对比度的作用，推导了出不同观测方向下目标物光谱对比度的计算公式，作为例子，给出海面上黑色物体的光谱对比度公式，也给出海面目标“被隐蔽”的条件。     

高能波控陆架的风暴沉积和风暴层序——以澳大利亚东南部陆架为例

根据浅层地震和钻孔资科,将澳大利亚东南部研究地区高能波控陆架风暴沉积分为直立风暴层、叠瓦状风暴层、无序风暴层、水平风暴层和纹层状风暴层等五类.各类风暴层及风暴层与非风暴层组合而成悬移风暴层序、悬移-推移混合风暴层序和推移风暴层序三大类.中陆架风暴沉积与现今近岸和水下岸坡相似,岩性、岩相和古生物属海岸带,风暴沉积厚,底板埋深大,组成物质粗.推断中陆架风暴沉积当形成于冰后期海侵、该地带处在近岸带和水下岸坡环境时,此时海面上升速度可能减缓,或趋近于零,甚至可能有短时间的下降.     

Analytic Solution of Interaction Between Surface Waves and Floating Elastic Plates with Elastic End-Restraints

Based on the dynamic theories of water waves and Mindlin plates,the analytic solution of interaction between surface waves and two-dimensional floating elastic plates with edge-restraint is constructed by use of the Wiener-Hopf technique.Firstly,without regard for elastic edge restraint,the wave-induced responses of elastic floating plate analyzed by the present method are in good agreement with the results from literature and experimental results.Therefore,it can be shown that the present method is valid.Secondly,three end-restraint cases(i.e.,the left-end elastic restraints,the both-end elastic restraints,and the right-end elastic restraints)are proposed to reduce the vibration of floating plates,in which the spring is used to connect the sea bottom and the floating plate's left(or right)edge.The relations between the spring stiffness and the parameters of wave-induced responses of floating plates are discussed.Moreover,the effective method to reduce the vibration of floating elastic plates can be obtained through comparison.

全新世苏北沿海岸线冲淤动态研究

探讨了10kaB.P.以来苏北海岸线的动态演变过程，结果表明，全新世本区曾遭受海侵，6kaB.P.前，苏北海岸线位于西冈一线，6kaB.P.至唐宋时期，海岸线变动较小，古砂堤成组出现，东冈代表了这个时期的海岸线，1128－1855年，黄河夺淮，海岸线东迁迅速，古砂堤不够发育。
