盐藻和β-胡萝卜素研究述评

养殖盐藻生产β-胡萝卜素是近十几年新兴起的研究领域，因其应用前途广内，现已成为微藻生物学的研究前沿和热点，预计本世纪末和下世纪初将有更大发展。鉴于我国在这方面文章不系统、不全面，本文从盐藻生物学、养殖学、β-胡萝卜素异构体、β-胡萝卜素形成生理等角度全面概述了该领域的研究现状，并提出存在的问题与研究方向。     

黑潮和中国近海环流

本文根据历史资料总结和讨论了黑潮对中国近海环流影响的基本结果,指出经巴士海峡进入南海和沿台湾海峡向北运动的黑潮分支,其年际变化明显,并认为该黑潮分支的运动状况对中国近海特别是南海和东海南部的中、下层环流影响显著,需要作进一步的调查研究。     

夜光藻的室内培养

夜光藻的室内培养对于研究夜光藻的生理生态特性及其增殖机理是一个关键性的环节。通过试验，发现在实验室条件下以扁藻作为饵料，夜光藻能良好的生长和繁殖，从而为夜光藻的室内培养解决了关键性的饵料问题，实现了国内夜光藻室内的长期培养。     

二色桌片参酶解液对转化细胞的效应

用二色桌片参（Mensamariaintercedens）酶解液处理转化的人胚肺成纤维细胞（NLF）后，细胞生长受到显著抑制，抑制率达64．84％，光镜下细胞透光性加强，铺展较好，细胞核形更为规则，核畸形现象减少；线粒体结构趋于正常；软琼脂集落实验表明，细胞集落形成率由23ｘ10－5下降至12．5ｘ10－5，裸小鼠致瘤实验显示抑瘤率为82．39％，差异显著（p＜5％）。结果提示，二色桌片参酶解液可能逆转转化的HLF细胞的恶性表型，对其有一定的诱导分化作用。

Outer wave number spectrum and statistical distribution of apparent wave number vector

Based on the ray theory and Longuet-Higgins’s linear model of sea waves, the joint distribution of wave envelope and apparent wave number vector is established. From the joint distribution, we define a new concept, namely the outer wave number spectrum, to describe the outer characteristics of ocean waves. The analytical form of the outer wave number spectrum, the probability distributions of the apparent wave number vector and its components are then derived. The outer wave number spectrum is compared with the inner wave number spectrum for the average status of wind-wave development corresponding to a peakness factor P = 3. Discussions on the similarity and difference between the outer wave number spectrum and inner one are also presented in the paper.     

Algorithm for HF radar vector current measurements

A new algorithm is proposed, called the stream function method (SFM) for producing vector current maps from radial data measured by dual-site high frequency surface wave radar (HFSWR). In SFM, a scalar stream function is constructed under some oceanographic assumptions. The function describes the two-dimensional (2-D) ocean surface water motion and is used to obtain the distribution of vector currents. The performance of SFM is evaluated using simulated radial data, which demonstrates that SFM has advantages over typical vectorial combination methods (VCM) both in error acceptance and robustness, and excels another method based on least-squares fitting (LSF) in recovering the complicated current models. Furthermore, SFM is capable of providing the total currents based on radials from single-site radar. We also test the assumptions of horizontal non-divergence in the simulation. The new algorithm is applied to the field experiment data of Wuhan University’s ocean state measuring and analyzing radar (OSMAR), collected in the coastal East China Sea during April 11–17, 2004. Quantitative comparisons are given between radar results by three current algorithms and in-situ current meter measurements. Preliminary analysis of the vertical current shear is given based on the current meter measurements.     

几种红藻和蓝藻的光合作用色素

分离纯化出几种海产红藻和一种蓝藻的光合作用色素,并测定了它们的化学性质和光谱学性质。这些藻类是3种红藻:多管藻(Polysiphonia urceolata)、橡叶藻(Phycodrys sp.)和条斑紫菜(Porphyra yezoensis);蓝藻:钝顶螺旋藻(Spirulina platensis)。用羟基磷灰石柱层析法从上述藻类中分离到几种不同的藻胆蛋白。经SDS-PAGE及光谱测定,发现条斑紫菜中的藻红蛋白不同于其它两种红藻。而橡叶藻中存在的两条藻红蛋白也有差异,条斑紫菜和钝顶螺旋藻中的两种别藻蓝蛋白之间也有区别。叶绿素分析表明,钝顶螺旋藻中叶绿素a的含量高于红藻中叶绿素a的含量。
