查询词典 foraminifer

Saline water and foraminifer are enriched in 7Li, and marine biogenetic carbonates are depleted in 7Li.

其中较小的δ^7Li值见于海相生物碳酸盐样品，较大的δ^7Li值见于某些盐湖卤水以及有孔虫的样品。

The composite section is compared with the Foraminifer's age which is early confirmed and the equation"y =-0.1909x + 304.83"is obtained.

利用现有的公认的晚白垩世有孔虫生物年代资料和复合剖面CS做线性回归分析，得到方程y =-

From the composite section, it can be found that some fossils'range zones are too short. Maybe it is caused by the fossils not preserved properly or the samples not collected comprehensively. Most fossils'first occurrence data are later than the ages which are defined by the MIDK4 composite section. It is probably caused by the Foraminifer zones in Tethyan- Himalaya which are not isochronous with other areas. It can also be recognized that there are two major extinction and revival events at the boundary of Cenomanian/Turonian and the boundary of Coniacian/ Santonian. They are coincident with the two Ocean Anoxic Events and can be considered as the typical response by creatures.

在复合剖面上可以发现：一些化石的延限非常短，这可能是由于化石保存不完整或者样品采集不全造成的；大部分化石的首现面年龄值都要晚于MIDK4数据库复合剖面给出的年龄值，这可能是由于特提斯喜马拉雅带与全球其他地区的有孔虫化石带不等时造成的；同时，可以在复合剖面上识别出在Cenomanian/Turonian界线附近和Coniacian/Santonian界线附近存在两次大规模的生物灭绝和复苏事件，这正好与两次大洋缺氧事件发生的时间一致，可以作为缺氧事件的生物标志。

Based on these, we will measure isotopic composition of boron in biological fossils, such as shell, foraminifer et al. producing from Ynaghu Village, Yanqing Basin, Beijing at early Quaternary and from the sediment of salt lake in Tibetan at Quaternary, and then offer a reliable boron isotopic evidence for determining their source and survival surroundings.

在此基础上对北京延庆杨户庄第四纪早期地层和青藏高原第四纪盐湖沉积产出的有孔虫、贝壳类等生物化石的硼同位素组成进行测定，为确定它们的海陆相来源及其生存环境提供硼同位素证据。

Paleoecological responses to midPleistocene climate transition at about 900 ka in the south China sea were mainly reflected by highfrequency fluctuations in planktonic foraminifer, isotopic, and other biologicalenvironmental records that indicated a sudden decrease in sea surface temperature.

中更新世气候转型在南海浮游有孔虫、氧同位素和其它生物记录上主要反映在900 ka BP前后发生高频率变化，特别是指示表层水骤然降温。

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。
