浙江省海塘塘顶高程的确定

介绍了浙江省海塘塘顶高程确定时所涉及的波浪爬高，越浪量等的计量，同时分析了1997年后浙江省海塘塘顶高程确定的方法，由已建海塘的塘顶高程分析可见，在背水坡和塘顶有保护措施的情况下，采用允许最大越波流量来控制海塘塘顶高程，可适当降低塘身高度。

Elemental geochemical records of seafloor hydrothermal activities in the sediments from the Okinawa Trough

The major and minor element contents in the sediment core H9 from the hydrothermal fields of the Okinawa Trough show a sharp change at the depth of 80 cm. The elements enriched in the upper 80 cm core are those enriched in the hydrothermal deposits and in the surface sediments recovered from the hydrothermal fields in the trough, which indicates the input of hydrothermal materials. Comparing with other hydrothermal sediments from Mid-ocean Ridges or the Lau Basin, the degree of the enrichment of elements iron, copper,cobalt, and nickel is relatively low. However, the enrichment of elements manganese, lead, arsenic, antimony and mercury is remarkable. The average contents of these elements in the upper 80 cm core sediments are three to six times those in the lower section, and 3~12 times those in the surface sediments which are not influenced by hydrothermal activities. Hydrothermal activities have contributed significant manganese, lead, arsenic, antimony and mercury to the sediments, and these elements are distinct indicators for the hydrothermal activity in the Okinawa Trough. The significant enrichment of these elements in Core H9 upward from the depth 80 cm indicates the start or the significant enhancing of the hydrothermal activity in this area at about 5 740 aB.P. The average accumulation rate of manganese during this period is about 40 461 μg/(cm2·ka), which is similar to the hydrothermal sediments in the Lau Basin or the East Pacific Rise.     

培养基对海藻真菌PT2菌株的生长及活性代谢产物合成的影响

本文采用PD、GPY、YES、SYE、GPM5种不同培养基培养海藻真菌菌株PT2，并对其在不同培养基中的生长情况、代谢产物的形成及抗肿瘤活性进行分析，旨在了解不同培养基对菌株生长和活性物质合成的影响．结果显示，PT2菌株在不同培养基上的培养特征及生长速率有所不同，液体培养基发酵液抽提物的抗肿瘤活性也有较大差别，其中SYE发酵液抽提物活性最强，对KB、Raji和Hela 3种肿瘤细胞的IC50分别为7．6μg／cm^3、2．4μg／cm^3和3．3μg／cm^3．采用HPLC法对不同抽提物进行分析，发现它们之间的组成成分有显著差异．本文的实验结果表明，不同培养基对该菌株的生长及活性代谢产物的合成具有显著的影响。

3D gravity modelling for Anyongbok Seamount in the East Sea

A seamount chain with an approximately WNW trend is observed in the northeastern Ulleung Basin. It has been argued that these seamounts, including two islands called Ulleung and Dok islands, were formed by a hotspot process or by ridge related volcanism. Many geological and geophysical studies have been done for all the seamounts and islands in the chain except Anyongbok Seamount, which is close to the proposed spreading ridge. We first report morphological characteristics, sediment distribution patterns, and the crustal thickness of Anyongbok Seamount using multibeam bathymetry data, seismic reflection profiles, and 3D gravity modeling. The morphology of Anyongbok Seamount shows a cone shaped feature and is characterized by the development of many flank cones and flank rift zones. The estimated surface volume is about 60 km³, and implies that the seamount is smaller than the other seamounts in the chain. No sediments have been observed on the seamount except the lower slope, which is covered by more than 1,000 m of strata. The crustal structure obtained from a 3D gravity modeling (GFR = 3.11, SD 3.82 = mGal) suggests that the seamount was formed around the boundary of the Ulleung Plateau and the Ulleung Basin, and the estimated crustal thickness is about 20 km, which is a little thicker than other nearby seamounts distributed along the northeastern boundary of the Ulleung Basin. This significant crustal thickness also implies that Anyongbok Seamount might not be related to ridge volcanism.     

台湾海峡毛颚动物分布的初步研究

本文分析了台湾海峡毛颚动物的种类组成、数量分布特征，并就其与环境因素的关系进行了初步探讨．结果显示与台湾海峡西部、东海等邻近海域相比，本区毛颚动物具种数少，数量小，季节变化幅度较小等特点．它的数量分布状况与闽斯沿岸流、南海西南季风漂流以及黑潮支流在本区运动消长有关。
