From the bottom up, the strata are the Fuxian, the Yan'an, the Zhiluo and the Anding Formations. In the past, it was thought that only the Yan'an Formation contains coal in the Jurassic systerm of the basin. However, recent explorations have shown that the Zhiluo Formation also has some minable coal seams in a certain area.

以往认为鄂尔多斯盆地的侏罗系延安组为含煤岩系，其他均为不含煤的地层，在近几年来的勘查中，发现直罗组也存在具有一定分布面积的可采煤层，笔者通过直罗组岩石露头、钻孔岩心和测井曲线的分析研究，划分了直罗组沉积相，并探索了直罗组的聚煤规律，对煤层进行了预测。

Through diazotization-lactonization,esterification, reduction, ether formation and double bond formation,the optically active--γ-benzyloxy methy-γ-butanolideXXIII and--γ-benzyloxy mothy-γ- butenolideXXV were preparedstarting from L-glutamic acid.

本论文采用易得的L-谷氨酸为原料，经重氮化-内酯化、酯化、还原、醚化和形成双键五步反应，合成了光学活性的化合物XXIII和XXV(Scheme 6，P.63)。

Although different geomorhopologic landscapes appeared unique geological characteristics because of the difference of their formation, the formation of geornorhopologic landscapes are related to the Geologic-tectonic evolutional history and the multicycle magmatic activities, especially the neotectonic movements.

尽管不同类型的地质地貌景观由于成因上的差异而显现出独特的地学特征，但地质地貌景观的形成均与新疆复杂的地质构造演化史和多旋回的岩浆活动、尤其是新构造运动密切相关。

The oil shales are found both in the Palaeogene Youganwo Formation and in the Neocene Shangcun Formation.

茂名盆地为伸展作用下形成的半地堑式断陷盆地，油页岩发育于古近系油柑窝组和新近系尚村组中。

Despite the Rossby Radius of Deformation around strong vortexes is much smaller than of the background, the results of experiments in the nondivergent barotropic model and in the shallow water model are similar. This indicates that there is little differences between vorticity dynamics and potential vorticity dynamics in the formation of the concentric eyewall structure of typhoons. The dynamics of this formation belongs to a slow manifold dynamics and the effect of the gravity waves is limited.

我们以浅水模式延续前人之正压双涡旋实验，虽然强涡旋周围的罗士比变形半径远小於背景环境值，但是涡旋交互作用结果和正压模式类似，亦即涡度动力和位涡动力在强台风形成双眼墙的结构之下并没有很大不同，皆属於慢速流形动力，重力波造成的影响很有限。

Testing tech with pump can provide a direct basis for knowing reservoir property (formation effective permeability) of nonflowing well dynamically, well's completion degree and red situation of formation, adjusting exploitation plan in injection well to conduct next step of treatment (especially for new well in new district).

随泵测试技术为动态了解非自喷井油藏的储层特性，井的完善程度、地层亏空情况，调整注水开发方案进行下一步增产措施提供了直接依据。

The addition of phosphorus has a negative effect on the tensile properties on account of its solubility in CuAl 2 , and the formation ofO 2 oxide particles, where the latter act as nucleation sites for the formation of the CuAl 2 phase.

磷的增加有O 2的氧化物颗粒，就考虑其在CuAl 2溶解度，及在的形成拉伸性能的负面影响下，作为后者的成核行为的网站编队CuAl 2相。

Methods BMSCs isolated from rabbit iliac bone marrow were culture-expanded in vitro. The injectable tissue-engineered bone constructed from autologous PRP, FG, and BMSCs was cultured in vitro, and its biological characteristics were observed including the time of gel formation, histological features, seed cell survival and microscopic structures. Results The constructed injectable tissue-engineered bone began gel formation within 20 to 30 s, and after a week-long culture, the gelatine began to degrade, and numerous well viable fusiform cells could be seen to adhere to the bottom of the Petil dish, Scanning electron microscopy identified globular and olivary cells embedded in the fibrin glue, and numerous small particles could be seen around of the cells.

从兔髂骨处抽取骨髓体外培养BMSCs并诱导向成骨细胞分化，抽取兔自体动脉血提取PRP，以FG、BMSCs、PRP共同构建可注射型组织下程骨并体外培养观察其生物学特性如凝胶形成时间，组织学特点、细胞存活情况及其超微结构特征等结果构建的可注射型组织工程骨可在短时间内形成凝胶，体外培养1周时其中细胞生长良好，电镜下见纤维蛋白网格结构致密，种子细胞及血小板颗粒分布广泛。

The Changxing Formation reef and shallow facies reservoir is a new type of reservoir having a great potentiality after Feixiaguan Formation oolitic beach was found.
