The dual structure of the complex fault depression in Songliao Basin and its geologic historic construction determined the existence of two sets of petroleum systems and their differences. The deep fault-depression group developed during Late Jurrasic to early Cretaceous and the particularity of the constructions of its inside sedimentary rock and volcanic rock determined the particularity of the natural gas enrichment conditions.

松辽盆地断拗复合的二元结构及独特的地质演化特征，决定了2套油气系统的存在和差异；晚侏罗－早白垩形成的深部断陷群及其内幕沉积岩和火山岩建造的特殊性，决定了天然气富集条件的特殊性。

We have extracted DNA from the inclusion of a dinosaur egg fossil from the Late Cretaceous in Xixia Henan,China, DNA fragments are isolated from the floccus in the cavity of the egg fossil,and confirmed by the method of random primer isotope labelling.

本文从河南省西峡晚白垩世的一枚保存方式特殊的恐龙蛋化石中提取DNA，经过￣32P同位素标记和电泳分析，发现在蛋内腔的絮状物样品中确有DNA片段存在。

If her countenance and hair had rather a floury appearance, as though from living in some transcendently, genteel Mill, it was rather because she was a chalky creation altogether, than because she mended her complexion with violet powder, or had turned grey.

倘若她的面容，她的头发，颇有点面粉似的外表，仿佛她居住在一个超凡闲雅的磨坊里，那是因为她一生下来便全身上下具有白垩土的颜色，倒不是因为她靠搽蓝紫色的粉来修饰自己的肤色，也不是因为她的头发已经花白了。

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 =-

在对藏南白垩纪沉积地质详细研究基础上，本文对尼泊尔喜马拉雅和Lhadkh喜马拉雅白垩系进行了对比。

in this paper can be summarized as follows: 1 Based on the Zongshan Section of Gamba and the Chuangde Section of Gyangze in southern Tibet, three Upper Cretaceous units have been recognized as black, gray and red ones.

本论文主要得出了以下几点认识： 1由西藏南部晚白垩世的岗巴宗山剖面和江孜床得剖面可以识别出三套岩层：黑层段，灰层段和红层段。

The Gamba basin of southern Tibet, is located in the east of Tethys tectonic region, whereexposes complete strata from late Cretaceous to Paleogene. The strata yield abundantfossils, and accurate biostratigraphic works have been done by previous studies.

西藏南部岗巴盆地位于位于特提斯构造域的东端，发育有完整的晚白垩世至古近纪地层，地层中化石丰富，前人根据化石研究准确地进行了地层时代的划分。
