The study on microstructure characteristics of the five pores on the surface of ostracoda at Nenjiang Formation of Songliao Basin in Cretaceous shows that during the depositional period of Nenjiang Formation in Cretaceous,Songliao Basin should be a continental depositional system and palaeolacustrine enviroment and furthermore its water body property should be fresh saltish.

本文对松辽盆地白垩纪嫩江组介形类化石壳体表面毛细管孔的显微构造特征研究表明，白垩纪嫩江组沉积时期，松辽古湖盆应为一陆相沉积体系，其水体性质应为淡水—少盐水的古湖泊环境。

Unlike previous models in which overexpression of the amyloid precursor protein results in amyloid plaque formation, have produced mice that overexpress only Aβ40 or Aβ42 and prove that Aβ42 is critical for the formation of amyloid deposits in vivo.

不同于早先调控淀粉样蛋白前体蛋白的动物模型，McGowan 等(Neuron， Vol 47， 191-199， 21 July 2005)培养了专一表达Aβ40或者 Aβ42的老鼠，结果直接证明了Aβ42 确实是引起淀粉样蛋白沉淀的主要因素，而不是Aβ40。

Voluminous volcanic rocks of the Tiaojishan Formation outcrop in the Western Hills of western Beijing, which are unconformably overlain by the volcanics of the Donglingtai Formation.

北京西山地区分布着大量的髫髻山组火山岩，区域上髫髻山组被东岭台组角度不整合覆盖。

The paper adopts some methods such as gas composition, carbon isotope, systematical analyzing and testing of reservoir bitumen biomarker from high evolutional natural gas and quantitative calculation of mixed gas, illustrates that natural gas from the section Ⅱ of Jialingjiang formation is mainly attributed to sapropel type organic matter gas of Permian, comes from carbonatite hydrocarbon rocks Permian which most of them are overmature, its main gas source has nothing to do with carbonatite hydrocarbon rocks of Jialingjiang formation themselves, presents in geochemistry characteristics of oil type cracked gas.

摘要通过对川中－川南过渡带西部的磨溪－潼南地区嘉二段天然气组成、碳同位素组成、高演化天然气储层沥青生物标志化合物的系统分析测试和混合成因气的定量估算，阐明了该区嘉二段天然气主要属于二叠系腐泥型有机质成因气，来源于二叠系过成熟为主的碳酸盐岩烃源，主力气源与嘉陵江组自身的碳酸盐岩烃源无关，并具有油型裂解气的地球化学特征。

The factors responsible for the gas richness in offshore Bohai are represen ted as follows:The thicker deposition sediments,it made the main source rock-Eoc ene Shahejie Formation reach overmature to generate gas;there is huge thickness of Oligocene source rock-Dongying Formation;there are strong Tertiary tectonic m ovements and high heat-flow in the offshore.

海域天然气比陆上富集的主要因素表现在：沉积厚度大，使得盆地内主要烃源岩始新世沙河街组达到高成熟生气阶段；存在巨厚的渐新世东营组烃源岩；具有较强的晚期构造运动和较高的热流值，在浅层也有天然气聚集的领域。

The results show that the vertical sintering speed changes notably with the proceeding of sintering process. After ignition and thermal retardation the bed permeability deteriorates and the sintering speed decreases notably because of the progress of physical chemistry reaction, formation and broaden of combustion zone, and formation of overwet zone. In about 25 min, the over wet zone vanishes, so the bed permeability meliorates and the speed arises rapidly.

结果表明：垂直烧结速度并非固定不变，而是随着烧结过程的逐步进行发生显著变化；点火保温后，随烧结物理化学反应的进行，燃烧带逐渐形成并变宽且产生过湿现象，导致料层的透气性显著变差，烧结速度显著下降，直至约25 min后过湿层完全消失，透气性变好，烧结速度迅速上升。

The calculated results indicate that the energy bathers for the formation of dimethyl ether and trimethyl oxonium ion inside HSAPO-34 zeolite are 1.68 and 0.93 eV, respectively. The suggested intermediate oxonium ylide is very unstable and the energy barriers for the formation of C-C bond are over 3.0 eV by concerted pathway.

结果表明，二甲醚和三甲基氧鎓离子在HSAPO-34分子筛上的生成能垒分别为1.68和0.93eV，中间体氧鎓叶立德不能稳定存在，同时表明C-C键通过协同反应形成的能垒均超过3.0ev。

In this paper, the author discovered Solenites murrayana L. et H. from Yaojie Formation of Middle Jurassic which was an important species of Ginkgophytes in Mesozoic during environmental palaeobotany study of Lanzhou-Minhe Basin. The epidermic structure of Solenites murrayana in Yaojie Formation is similar to that of Solenites murrayana in Yorkshire Jurassic of UK by cuticular analyses.

作者在兰州-民和盆进行环境古植物学的研究中，于中侏罗统窑街组发现了中生代银杏类植物化石的重要代表穆雷似管状叶Solenitesmurrayana L.et H。，通过分析S.murrayana的表皮构造，得出与英国约克郡侏罗纪的S.murrayana具有明显相似性的特点。

Based on the identification of the sequence boundry with the comprehensive analyses of the seismic, well logging and well drilling data, the palaeogene in Jiyang depression can be divided into one lst-order and three 2nd-order sequences, of which six 3rd-order sequences can be subdivided from the third stage of Shahejie formation to Dongying formation.
