本文介绍了１９９６年冬季首次辽东湾生态环境调查中的海洋背景条件。扼要地阐述了辽东湾海冰一般概况，分析辽东湾冰样晶体结构、存储条件及其与冰内和冰下海水叶绿素之间的关系。辽东湾冰内叶绿素符合其它结冰海区的一般规律。根据辽东湾冰层底部实测盐度变化规律阐明海冰对冰下海水营养盐的贡献。最后对深入开展结冰海区生态环境调查工作的技术、侧重点和意义做了讨论。     

“华夏古陆”考异

自葛利普创名“华夏古陆”以来,经过半个多世纪的论辩与考订,对其地质构造属性,至今仍然否定与肯定交迭起伏,莫衷一是,本文从推覆构造,陆地漂移等实际资料着手,加以论证,认为它是经历深刻改造和发生巨大位移的变质岩断片体,地质构造属性已非“华夏古陆”原义。     

Release of bioactive active iodine in kelp

The release process and influencing factors of bioactive iodine of kelp are systemically studied by leaching experiment. The results showed that the bioactive iodine of kelp can be released rapidly and the principal form of iodine in lixivium is I^- . There is a dynamic process between the release and absorption of iodine. With the increase of leaching water, the gross amounts of released iodine rise.There also exists a transforming process among I^- , IO3^- and organic iodine in lixivium.     

Distribution characteristics of ammonia-oxidizing bacteria in the Typha latifolia constructed wetlands using fluorescent in situ hybridization(FISH)

A molecular biology method, fluorescent in situ hybridization（FISH）, in which the pre-treatment was improved in allusion to the media of the constructed wetlands（CW）, e.g. the soil and the grit, was used to investigate the vertical distribution characteristics of ammonia-oxidizing bacteria（AOB） quantity and the relation with oxidation-reduction potential（ORP） in the Typha latifolia constructed wetlands under three different Ioadings in summer from May to September. Results showed that the quantity of the AOB decreased in the Typha latifolia CW with the increase of vertical depth. However, the AOB quantity was 2-4 times the quantity of the control in the root area. Additionally, ORP in the rhizosphere was found to be higher than other areas, which showed that Typha latifolia CW was in an aerobic state in summer when using simulated non-point sewage at the rural area of Taihu Lake in China and small town combined sewage.

污水处理单元构筑物费用函数研究

文中提出了处理效度E(Comprehensive Treatment Efficiency)的含义,它的计算表达式为E=(Q1/Q2)(B×αB+S×αs+N×αn),对费用函数拟合涉及的一些概念进行了规范探讨,用式C=S×α+V×β复合单元构筑物成本;拟合了C′(E)=α.ln[(1+E)/(1-E)],C(Q,E)=α.ln[(1+E)/(1-E)]Qβ形式的单元构筑物费用函数.     

电极旋转放电条件下O3合成效率的理论研究

根据低温等离子体理论和电磁场理论，在实验的基础上研究了电极旋转条件下低温等离子体的产生机制和臭氧的合成机制，分析了放电过程中二次放电重叠对臭氧合成的影响，建立了旋转放电与二次放电的理论模型，并根据这一理论模型导出电极旋转条件下的臭氧合成效率与二次放电重叠概率以及电极旋转速度间的理论关系．这一理论结果表明：二次放电重叠使得臭氧合成效率降低，而电极以适当地速度旋转则可以有效地避免二次放电的重叠，从而提高臭氧的合成效率．理论值和实验结果能够较好地吻合．
