台湾海峡中北部表层沉积物中介形类拟生态的研究

台湾海峡中北部介形类共６９属１１５种，受复杂的海底地形及海流、水团等环境因素影响，分为４个分布区；沿岸低值区，西南部高富集区，东北部密集区及中部过渡区，介形类属种以东海、南海组成的分子较多，显示出海流因素起主要作用。     

Parabolic Wave Propagation Modelling in Orthogonal Coordinate Systems

This paper presents a numerical model study of the propagation of water waves using the parabolic approximation of the mild-slope equation in the orthogonal coordinate system. Two types of coordinate systems are studied: (a) a general form of orthogonal coordinate system and (b) the conformal system, a special form of orthogonal coordinate system. Two typical examples, namely, expanded breakwaters and a circular channel, are studied to validate the model. First, the examples are studied by use of the general orthogonal coordinates. Then the same examples are computed by use of the confonnal system. The computational results show that the confonnal coordinate system generally gives better predictions than the general orthogonal system. A numerical technique for generating the conformal grid is combined with the numerical model to improve the practicability of the model. The comparison between the result from the numerical grid system and that from the analytical grid system shows that reliable computational results can be obtained by use of the numerical confonnal grid system.

Guadalupian （Middle Permian） Conodont Faunas at Shangsi Section, Northeast Sichuan Province

This study recovered the Guadalupian conodont faunas from Shangsi (上寺) Section in Northeast Sichuan (四川). Four genera and nine species were identified, and three conodont zones were recognized and established; they include Jinogondolella nankingensis Zone, J. aserrata Zone, and J. postserrata Zone. The Roadian and Wordian boundary is set in the interval 5 m from the top of Bed 86 by the first appearance of the conodont J. aserrata. The Wordian and Capitanian boundary is set in the interval 2.3 m from the top of the Bed 95 by the first appearance of J. postserrata. Most of the specimens demonstrated low color alteration index (CAI) as 1.5-3, indicating that most part of the Maokou (茅口) Formation may have the suitable thermal conditions for the formation of oil source rocks.

水厂V型滤池的自动化控制设计

V型滤池属于快滤池中的一种,因其进水槽形状呈V字形而得名,于20世纪80年代末从法国Degremont公司引入我国,并大面积推广使用。由于每个滤池一般设6～7个阀门,每座滤池设2～3台鼓风机和3台冲洗水泵,滤池如果靠人工手动操作实现恒水位过滤和反冲洗,操作强度非常之大,因此采用PLC控制系统实现自动恒水位过滤和反冲洗显得尤为重要。结合胜利石油管理局供水公司耿井水厂的10万t／aV型滤池阐述V型滤池的自动化控制。

河南西峡地区晚白垩世介形虫的发现及其地层意义

2005年在河南西峡含恐龙蛋层中首次发现介形虫化石,产自红山水库-丹水剖面上白垩统赵营组下段64层,是以Eucypris-Mongolocypris-Cypridea-Talicypridea为特征的介形虫化石组合,由12属20余种组成.其中Talicypridea是中国、蒙古和东亚晚白垩世最典型的化石,在非洲刚果及南美阿根廷的晚白垩世地层中也有分布,因此赵营组的时代无疑应归属为晚白垩世.赵营组介形虫化石的新发现,为地层的划分对比、沉积环境的演变和盆地的演化研究提供了重要的依据.
