有孔虫

Measurement of Mg/Ca ratio of foraminifera shell is the most popular means in calculating seawater paleotemperature now. It is applicable in low and high latitude areas, to determine surface and deep seawater temperatures.

有孔虫壳体的Mg/Ca比值测定是目前估算海水古温度最受重视的方法，适用於低纬和高纬、表层和深层海水古温度的测定。

Total 28 samples were collected from the section of 385.8—386.4 mcd at ODP Site 1144 (20°3.18′N , 117°25.14′E , water depth 2 037 m), northern South China Sea, and microtektite, planktonic foraminifera and stable isotope analyses were performed in order to evaluate the effect of the mid-Pleistocene impact on microplanktonic communities and environment.

本文对采自南海北部 ODP114 4站(2 0°3.18′N，117°2 5 。14′E，水深 2 0 37m) 385 。8— 386 。4 m层段的 2 8个沉积物样品进行了微玻陨石、浮游有孔虫及其同位素分析，以评估中更新世撞击事件对环境的影响。微玻陨石见于孔深 386 。12— 386 。38m，而集中分布在 386 。2 2— 386 。2 5 m厚约 3cm的地层中。

Cyanobacteria played an important role as the producers in the ecosystem, while the euryhalinous and benthic faunas were the main customers, including low-diversity microgastropods, ostracods, and disaster foraminifers.

蓝细菌作为生产者是该生态系的基础，种类单调的小型腹足类和介形虫等广盐性多细胞生物和灾后残存的有孔虫则是该生态系中的主要消费者。

Oil is from the age of the ancient organic materials (mainly single-celled plants, such as blue - green seaweed; single-cell animals, such as foraminifera) deposition, after a long-term physical and chemical changes in production.

石油是由古地质年代有机物质（主要是单细胞植物，如蓝-绿海藻类；单细胞动物，如有孔虫类）沉积后，经过长期物理、化学变化而生成。

There is a distinct relationship between the content of planktonic forarminifera and water depth which is apparently different in the shelf and in the slope to deep sea basin.

但在陆架区和陆坡－深海盆区，两者关系完全不同：在陆架区随水深增加浮游有孔虫百分含量明显增大，而在陆坡－深海盆区，两者呈负相关关系。

Multiple experiments such as grain-sized separation , magnetic mineral analysis, magnetic parameters measurement were made on 110 surface samples and 64 samples of the 180 core sediment taken from the shelf of the East China Sea to abyssal plain of the Okinawa Trough .

本文选取东海陆架至冲绳海槽槽底平原的代表性沉积样品110个和已有研究基础的DH180岩心样品，通过颗粒分离、磁性矿物分析、趋磁细菌培养、浮游有孔虫δ~(18)O测定、AMS~(14)C测年、多种磁学参数测量(包括磁化率、等温剩磁、x-T热磁曲线、磁滞回线、非磁滞剩磁和饱和等温剩磁等)等试验手段，分析探讨了不同粒级沉积物对磁性的贡献、沉积物磁性与物质来源及环境的内在联系、短期古海洋事件的环境磁学表现等科学问题。

This paper enumerates nine macroscopic climatic indicators in the study of China's Quaternary climate:Quaternary glacial vestiges,periglacial structure, mammal fossils,plant fossils,mollusk fossils,foramin- iferal fossils,lithology,karst and sea-level oscillation.

本文首先列述了中国第四纪气候研究中9种主要宏观气候标志：冰川作用遗迹、冰缘构造，哺乳动物、植物、软体动物、有孔虫化石，岩性、岩溶及海平面升降等方面的特征。

The available results found that atmospheric p CO2 variations reconstructed according to boron isotopes of marine foraminifers agree well with the records from Vostok ice cores.

现有的研究证实利用海洋浮游有孔虫硼同位素重建的大气CO2浓度变化与Vostok冰芯记录的大气CO2浓度变化吻合地很好。

This paper chooses the core of MD3050 on the Hamm plateau in West Philippine Sea, to appraisal and statistics the biota of planktonic foraminifera on the sediment systematically.

本文选取位于西菲律宾海本哈姆高原上的岩心MD3050，对沉积物中的浮游有孔虫生物群进行系统地鉴定和统计。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
