CHARACTERIZATION OF LACTATE DEHYDROGENASE ISOZYME PATTERN AND MORPHOLOGY OF THREE MARINE FISH CELL LINES

Three continuous marine fish cell lines of FG (i. e., Hounder Gill) from flounder (Paralichthys olivaceus) gill, SPH (i. e. , Sea Perch Heart) from sea perch (Lateolabrax japonicus) heart and RSBF (i.e., Red Sea Bream Fin) from red sea bream (Pagrosomus major) fin, were characterized by lactate dehydrogenase (LDH) isozyme and morphological analysis. The LDH isozyme patterns of these three cell lines and their corresponding tissues of origin were investigated and compared. The results showed: (1) No difference was found in the LDH isozyme patterns of FG and flounder gill tissue. However, the LDH isozyme patterns of SPH and RSBF were significantly different from their corresponding tissues of origin; (2) LDH isozyme patterns of FG, SPH and RSBF were markedly different from each other and could serve as genetic markers for species identification and detection of cross contamination. Morphological change analysis of these three cell lines in comparison to their original tissues indicated that FG cells still appeared epithelioid without morphological transformation. However, morphological changes were found in SPH and RSBF compared to their original tissues. Therefore, the cellular morphology was still plastic in the relatively stable culture conditions, and it was possible that change of LDH patterns wasrelated to morphological changes of fish cells in vitro.

FUZZY COMPREHENSIVE EVALUATION OF CONTAINER TRANSPORTATION MODES ALONG THE CHANGJIANG RIVER MAIN LINE AND ITS DELTA AREA

The Changjiang River (Yangtze) is one of the fastest growth areas of container transportation in Chi-na. Rail, road and water transportation have competed against each other for container transportation in the Chang-jiang River main line and its delta area. It is of significance to assess these different transportation modes scientifi-cally in order to organize container transportation efficiently in this area and make decision for integral plan and construction of transportation system in this area. This paper outlines application of fuzzy comprehensive evaluation to appraise different modes of typical direction of containers. Twelve assessment indexes were decided. Membership functions were formulated. Evaluation results indicated that road transportation was optimal mode in the Changjiang River delta area, however water transportation was the primary way in the Changjiang River main line.     

模糊物元分析在金刚石钻头综合评价中的应用

针对金刚石钻头综合评价中各指标的不相容性和模糊性,提出基于模糊物元分析的金刚石钻头综合评价方法.该方法将待评价金刚石钻头、评价指标及其特征值作为物元,根据专家经验和工程实际建立关联函数,通过计算综合关联度得到最优的金刚石钻头.用实例与模糊优化理论模型等进行了对比,得到了一致的结果.     

地下水功能评价指标选取依据与原则的讨论

地下水功能评价是实现地下水可持续利用和有效保护生态及地质环境的重要基础,而评价的关键是指标的选取。本文在遵循主导性、可度量、可操作、覆盖面广和灵活性原则的基础上,考虑地下水功能的影响因素、表征特征,从地下水系统的驱动、状态和响应因子中筛选出地下水功能评价的指标,从而为地下水功能评价建立了一套行之有效的指标集。

预报指标自动归纳和实时自动推理预报系统

本文结合实际应用介绍一种人工智能系统。系统的重要特点是,根据预报指标经验知识的产生过程的机理性知识所设计成功的系统主程序之一的“预报指标自动归纳程序”,能够通过对多因子历史资料的分析归纳,自动生成含有较全面知识规则的规则库。有关专家只须凭感性经验提供可能因子和原始资料,系统便能帮助升华出理性的经验规则,自动建成某一专项业务的应用预报系统。对这种“母系统”的反复使用,就可以根据不同类别的资料生成相应的多种应用系统。既适用于气象上风雨暑寒各类天气预报,也适用于其他某些专业,如水文、地震等的定性预报或分析。 本文除简单介绍系统的构造、功能、设计原理之外,还给出一个应用实例,介绍了如何使用本系统去产生应用性系统的具体方法步骤。     

扇贝外寄生车轮虫（Trichodina jadranica Raabe，1958）的形态学研究 （原生动物：纤毛门：缘毛目）

采用Ｗｉｌｂｅｒｔ蛋白银法及Ｃｈａｔｔｏｎ—Ｌｗｏｆｆ银浸法对一种附生于栉孔扇贝鳃丝上的寄生车轮虫进行了光镜水平下的研究。依据其形态学和纤毛图式特征，该种被鉴定为ＴｒｉｃｈｏｄｉｎａｊａｄｒａｎｉｃａＲａａｂｅ，１９５８．此为我国新记录，同时也是第一例有关外寄生于扇贝鳃表纤毛虫原生动物的报道。
