Experiments in numerical modelling of the Pacific sea surface temperature anomalies

By using the atmosphere-ocean coupled model (CGCM) which is composed of a 2-level global atmospheric general circulation model and a 4-layer Pacific oceanic general circulation model developed in the Institute of Atmospheric Physics of Chinese Academy of Sciences, and two model climatological fields got from the two independent models' numerical integrations respectively, the Pacific sea surface temperature anomalies (SSTA) from 1988 to 1989 are simulated in this paper with observed atmospheric general circulation data and sea surface temperature fields as initial conditions and monthly coupling scheme. In order to remove systematic biases of the model climatological fields, interaction variables between atmosphere and ocean are also corrected simultaneously. The experiments show that the simulation results can be improved effectively if these interaction variables are corrected in spite of the fact that there always exist systematic biases in independent numerical simulations of atmospheric part and oc     

大黄鱼(Pseudosciaena crocea)转铁蛋白(Tf)基因克隆及序列分析

提要应用RNeasy animal mini试剂盒抽提大黄鱼total RNA,逆转录合成模板cDNA;同时综合分析从GenBank数据库查询到已报道的转铁蛋白(Tf)基因序列,先设计并合成扩增引物扩增出大黄鱼转铁蛋白部分基因序列,再应用RACE技术,克隆出大黄鱼转铁蛋白全长cDNA基因,全长2461个核苷酸,编码661个氨基酸。应用WCG软件包,采用DNADIST和NEIGHBOR分析方法,构建了转铁蛋白系统进化树。树图显示与传统的分类地位大致相符,可以看出转铁蛋白在海水鱼和淡水鱼的进化上的差异,同时也显示大黄鱼Tf与真鲷的同源性最高。     

中国近海及其附近海域若干涡旋研究综述 Ⅰ.南海和台湾以东海域

综述了南海和台湾以东海域若干气旋型和反气旋型涡旋研究.在南海存在着许多活跃的中尺度涡,我们分别对南海中、南部海域和南海北部海域中尺度涡作了评述.在南海北部海域,目前最感兴趣的问题为:南海水与西菲律宾海通过吕宋海峡的交换的物理过程,以及黑潮是否以反气旋流套形式进入南海.这些问题目前尚不清楚,尤其是这些问题的机理.这些问题必须通过今后深入和细致的、长时间的海流和水文观测,以及长时间卫星遥感观测资料的论证才能逐渐认识清楚.台湾以东海域,黑潮两侧经常出现中尺度涡,而且变化较大而复杂.文中着重讨论兰屿冷涡和台湾东北的气旋式冷涡.     

96孔酶标板法测定中国对虾血淋巴上清液抗菌活力和酚氧化酶活性的初步研究

用96孔酶标板法测量单尾中国对虾血淋巴上清液抗菌（Uα）应力和过氧化酶活性。实验表明，该法具有以下优点：1）可测定大批单尾对虾血淋巴上清液的抗菌活力，酚氧化酶活性；2）所需对虾血淋巴上清液微量化；3）用酶标仪读取酶的活性，减少了不同试验者人为读数时的误差；4）重复性高。

Wave-Current Forces on Small Square Cylinders (Part I)

-Based on the extended Morison Equation and model tests, the in-line forces on small square cylinders caused by waves (regular and irregular) and currents are analyzed in detail in this paper. The hydrodynamic coefficient CD and Cu related to KC number and the effect of direction of wave incidence are also given, which can be used in engineering practice.     

薛家岛湾沉积动力学特征及海港开发研究

于１９９０年秋对胶州湾内的薛家岛湾进行海洋水动力条件及积动力学特征,泥沙运动规律研究,为开发建设港口提供科学依据。结果表明,湾内深大于１ｍ的海底泥沙发生“全面移动”的时间,一年内仅有１－２ｄ,其余处于稳定状态或“表面移动”状态。湾内泥沙来源很少,预计建港后,港池和航道年平均回淤量分别小于１６ｃｍ,１０ｃｍ对于开发中小型港口十分有利。

台湾山地的雨影效应及其表现

台湾岛的雨量受台湾山地的雨影效应影响明显,各地各月随着风向的不同,雨量表现出很大的差异。福建沿海一线存在着一个雨量低值区,主要是由于该地带所处的地理位置及地形条件所决定,与台湾山地的雨影效应无关。
