利用美国国家大气研究中心的CCSM2全球气候系统模式以及重建的古地理资料研究了晚白垩世(80 Ma)东亚的古气候特征。

In this paper,the characteristics of the East Asian climate and the impacts of atmospheric CO2 concentration variation on the East Asian climate were examined by using the Community Climate System Model version 2(CCSM 2.0)developed by the National Center for Atmospheric Researchas well as the reconstructed paleogeographic data of the Late Cretaceous(80Ma).

利用美国国家大气研究中心的CCSM2.0全球气候系统模式，并结合重建的古地理资料，研究了晚白垩世(80Ma)东亚气候特征以及CO2浓度变化对东亚气候的影响。

The volcanic rocks of Early Cretaceous Yingcheng Formation contain abundant perlitic rocks and they are important petroliferous layers in Songliao basin.

松辽盆地早白垩世营城组火山岩系含有丰富的珍珠岩，为松辽盆地重要的油气勘探目的层位。

Coussy's poroplastic theory is used for the extension of this model to describe poromechanical coupling of chalk. According to the general framework of poro-elasto-plastic modelling, the concepts of the effective stress tensors, especially the concept of plastic effective stress tensor, are discussed.

基于这一认识，将Coussy孔隙塑性理论扩展用于研究饱和白垩岩的孔隙塑性力学特性，根据孔隙弹塑性力学的一般框架，讨论在弹塑性域上有效应力尤其是塑性有效应力概念的有效性。

During the Late Jurassic, quartzitic sandstones came from stable passive continental margin.

Determined the formation mechanism and their time—space distributgion pattern, the following conclusion were drawn: the key element in establish a depositional system is the identification of exceptional reflectional stracture, and the identification of the palaeodrainagte pattern have extrordinary influence on the restoration of the depositional environment.

建立了侏罗—白垩系青山口组共5个时期的沉积体系分布图，指明了沉积体形成机制和时空展布特征，并认为：识别特殊反射结构是建立沉积体系的关键，判断古水系对恢复沉积环境具有重要意义。

Investigation results demonstrate that the age of intermediate to alkaline potash rich volcanic rocks of the first cycle of the Qingshan Formation is 109.9±0.6 Ma; and the age of the acidic rhyolitic volcanic rocks of the second cycle of the Qingshan Formation ...

结果表明，青山组第一旋回中偏碱性富钾火山岩的形成年龄为10 9.9± 0 。6Ma ，第二旋回酸性流纹质火山岩形成年龄为 10 8.2± 0 。6Ma ，据此确定胶莱盆地青山组火山岩应为早白垩世岩浆活动的产物。
