玻璃钢渔船船体材料切片之弯曲试验研究

玻璃钢渔船有很多优异的性能，因而有逐渐取代木质渔船的趋势。为推进玻璃钢渔船的产业化进程，作者在查阅了大量国内外有关资料的基础上，进行了玻璃钢渔船体材料切片的弯曲试验，最终提出了我国玻璃钢渔船船体材料切片的弯曲试验规程，以供我国今后制定玻璃钢渔船材料试验标准作参考。     

Spatial Modeling and Analysis for Shoreline Change Detection and Coastal Erosion Monitoring

Coastal erosion presents a serious problem throughout U.S. coastal areas. The Ohio Geological Survey estimates that more than 3,200 acres of Ohio's Lake Erie shore have been lost to erosion since the 1870s, resulting in economic losses exceeding tens of millions of dollars per year. This article presents research results of a project that monitors shoreline erosion using high-resolution imagery and examines erosion causes. Spatial modeling and analysis methods are applied to the project area along the south shore of Lake Erie. The shoreline is represented as a dynamically-segmented linear model that is linked to a large amount of data describing shoreline changes. A new method computes an instantaneous shoreline using a digital water level model, a coastal terrain model, and bathymetric data. This method provides an algorithm for deriving the Mean-Lower Low Water (MLLW) and the Mean High Water (MHW) shorelines that are essential to navigation charts. The results describe a part of our effort towards a coastal spatial information infrastructure to support management and decision-making in the dynamic coastal environment.

利用地下水水位资料推求水文地质参数

依据模糊集合理论,提出了反求水文地质参数的一种新方法,即用模糊模式识别评价计算水位与观测水位的拟合程度,依模糊ISODATA聚类法的原理建立目标函数,以相应的聚类中心作为要求的水文地质参数。     

口服免疫药物后中国对虾某些血淋巴因子的测定及方法研究

于１９９１年４－９月，以海捕中国对虾亲虾及养殖中国对虾为材料，运用单向免疫扩散（ＳＲＩＤ）方法测定对虾血淋巴免疫因子，并采用经改进后的Ｈｏｒｏｗｉｔｚ等人的方法测定对虾体内的酚氧化酶（ＰＯ）活性，目的在于运用该两种方法对口服不同免疫药物的养殖对虾的血淋巴免疫因子及ＰＯ活力进行测定。对亲虾和养殖对虾口服不同免疫药物前后的测定结果表明，几种情况下的对虾血淋巴中均存在类似ＩｇＭ的因子，血细胞中存在酚氧化

埃尔－尼诺过程与渤海气温异常

本文统计分析了渤海气温异常月份与埃尔－尼诺过程的关系，结果得出：在埃尔－尼诺年及其前后一年，渤海气温异常冷月占优势；在埃尔－尼诺持续期内，春季渤海气温出现异常冷月的百分率高达７３％。埃尔－尼诺与渤海气温异常关系的分析结果，表明了在海－气相互作用过程中，二者互为因果关系的事实。     

An ecological study on the fouling organisms in Yantai Harbour

Yantai Harbour (37°33′15″N , 121°23′42″E) is situated at the north coast of Shandong Peninsula and is a large fishing and commercial port of North China. From June 1983 to May 1984, a yearly panel test on fouling organisms was carried out at the non-fixed jetties in the inner and outer harbour. The test method was according to "the Marine Survey
