东海大规模赤潮危害影响的实验研究——对黑褐新糠虾和卤虫的毒性效应

The effects of Prorocentrum donghaiense,Karenia mikimotoi,Alexandrium catenella,the causative species of Harmful Algal Blooms in the East China Sea,on the survival and growth of Neomysis awatschensis and Artemia salina were investigated.And the toxicity of eleven strains of Alexandrium----A.lusitanicum(AL-1)、A.minutum(AM-1)、A.spp.(A-K)、A.tamarense(ATHK,ATCI02,ATCI03,AT5-1,AT5-3,AT-6)、A.affine(AS-1,AC-1) to the two above organisms were compared. The results showed that P.donghaiense and K.mikimotoi had no adverse effect on the survival and growth of N.awatschensis and A.salina at 96h.However,the survival rate of N.awatschensis and A.salina declined linearly with the increasing density of A.catenella,and the 96h LC₅₀ for N.awatschensis and A.salina was 4500 and 460 cells/mL,respectively, Five strains of Alexandrium----A.spp,A.lusitanicum (AL-1),A.tamarense(AT5-3,AT-6) and A.affine (AS-1)at the density of 4000cells/mL and 96h had no adverse impacts on N.awatschensis. But other six strains of Alexandrium a.Tamarense(AT5-1,ATHK,ATCI02,ATCI03),A.affine(AC-1) and A.minutum(AM-1)decreased the survival fate of N.awatschensis significantly. Two strains of Alexandrium----A.lusitanicum(AL-1) and A.tamarense(AT-6),at the density of 500cells/mL. had no adverse effects on A.salina in 96h;while the other Alexandrium strains all had adverse effeets on the survival of a.salina, A.salina could increase its length with the increasing density of P.donghaiense,K.mikimotoi and A.luxitanicum. The results indicate that P.donghaiense and K.mikimotoi have nio significant effect on the survival of crustaeean zoop lankton in a short period. But several Alexandrium specised/strains could influence the survival of crustacean zooplankton likely by non-PSP substances. A.salina is shown to be more sensitive than N.awatschensis as test organisms to harmful species.     

添加纳米TiO2的氯醚树脂的XPS分析

在紫外线老化前后,利用光电子能谱(XPS)研究了分别添加金红石型和锐钛型纳米TiO2的氯醚树脂。研究发现,氯醚树脂中氯、氧元素具有表面富积现象——趋肤效应,而钛和碳元素在内层聚集;添加颜料粒子越小,在表面含量越大;金红石型纳米二氧化钛紫外屏蔽性好,减缓树脂老化;而锐钛型纳米二氧化钛具有显著的光催化活性,加速树脂老化。因此,金红石型纳米二氧化钛将是一种有前途的紫外线吸收剂。

Non-Simultaneous Failure of Ice in Front of Multi-Leg Structures

Because the multi-leg jacket structure is the major type of offshore structures in the Bohai Sea, the study of non-si-multaneous failure of i鏴 on multi-leg structures is important. However, the non-simultaneous failure has not been consid-ered in engineering design until now, obviously resulting in costly design and notable waste. To resolve this problem, this paper, by means of analysis of experimental data, calculates the coefficient of the non-simultaneous failure for the double-pile structure, the square four-leg structure, the single-line multi-pile structure, and the conical structure, respectively, and provides some reference criteria for engineering design.     

用Matlab中的Neural Network Toolbox仿真赤道东太平洋SST的预报模型

基于ＮＣＥＰ／ＮＣＡＲ再分析资料和ＣＯＡＤＳ海洋资料中的全球月平均海平面气压场、８５０hPa纬向风场及海洋温度场，利用Ｍatlab中的Ｎeural Network Toolbox仿真环境和ＢＰ模型改进算法比较准确地仿真和反演出了南方涛动指数、赤道纬向风指数和滞后的赤道东太平洋海温之间的动力结构和预报模型。该模型具有很好的拟合精度和可行的预报效果。可在一定时效内预测赤道东太平洋月平均海温的变化趋势。由于所建系统是具有直接因果关系的预报模型，因此不仅可直接用于预测，而且可有效避免类拟非线性微分方程组在积分过程中由于对初值敏感性而可能产生的对预报结果的不确定性。
