有关盆地演化与下降的论文中,观点五花八门,多少反映了认识不统一的现状。有关文章不难按其内容分为:关于盆地下降地球物理模式的和主要描述盆地性质的。除个别例外,描述性的文章对盆地的升降历史都没有应用地球物理模式作周密的定量检验。

犁形正断层在沉积盆地形成中的重要性正在愈益明显。根据反射地震剖面和地面观测,可区分出以下四种发生类型:1.涉及基底的犁形正断层,这种基底伴有某些地壳减薄。这样的断层出现于裂谷形成期,这类裂谷常常先于被动陆缘的形成而出现(例如比斯开湾,加里西亚浅滩);2.表层松软沉积物的犁形正断层作用,与三角洲体系有关,或与和被动陆缘沉降相联系的漂移层系有关(例如墨西哥湾);3.与在活动陆缘产生的加积楔状体有关的犁形正断层作用(例如哥伦比亚);4.造山期和造山后的断层作用,它与造山系及其部分前沿地的引张及剪切有关(例如大盆地)。根据对大陆边缘和晚造山盆地的观测,正断层在“地槽”和褶皱带(例如阿尔卑斯)演化中的作用得到了被更好的理解。

埃·休斯(Eduard Suess)在他的《地球面貌》一文中引进了铲形断层的概念,他描述了法国北部、比利时和德国煤矿区向上凹曲的断层面,并注意到这类断层的横断面形态像铲(希腊语Listron shovel)。多年来,德国在煤矿区工作的地质学家一直采用这一术语。但是,除中欧以外其它地方几乎没有得到承认。Cloos (1936)虽然在粘土实验中对铲形正断层系作了详尽说明,但是,他还是认为应该将铲形断层这一术语限制在冲断层为好。Kirch-mayer和Mohr(1963)对曲线型的和曲面型的构造要素的术语作了详细的评述,并且列举了一系列含煤岩系、不含煤岩系中的,以及岩石变形实验产生的铲形断层的例子。这些作者还认为地表地质的研究不容易揭示出断层的铲形性质,因为露头条件常常不能反映断层面的几

Recently, a bulk nickelate superconductor La3Ni2O7is discovered at pressures with a remarkable high transition temperature Tc～ 80 K. Here, we study a Hubbard model with tight-binding parameters derived from ab initio calculations of La3Ni2O7,by employing large scale determinant quantum Monte Carlo and cellular dynamical mean-field theory. Our result suggests that the superexchange couplings in this system are comparable to that of cuprates. The system is a charge transfer insulator as the hole concentration becomes four per site at large Hubbard U. Upon hole doping, two low-energy spin-singlet bands emerge in the system exhibiting distinct correlation properties: while the one composed of the out-of-plane Ni-d3z2-r2and O-pzorbitals demonstrates strong antiferromagnetic correlations and narrow effective bandwidth, the in-plane singlet band consisting of the Ni-dx2-y2and O-px/pyorbitals is in general more itinerant. Over a broad range of hole doping, the doped holes occupy primarily the dx2-y2and px/pyorbitals, whereas the d3z2-r2and pzorbitals retain underdoped. we propose an effective t-J model to capture the relevant physics and discuss the implications of our result for comprehending the La3Ni2O7superconductivity.

we investigated the emission properties of Eu3+-doped GdNbO4-based oxide phosphors,aiming at improving the Eu3+emission by codoping of Bi3+and Li+.Eu3+singly doped,Eu3+and Bi3+doubly doped,and Eu3+,Bi3+,and Li+triply doped GdNbO4were prepared using a high-temperature solid-state reaction *** red-orange emissions from Eu3+in the singly doped samples are significantly improved by the codoping of Bi3+,mainly due to the energy transfer from Bi3+to Eu3+.The additional codoping of Li+is found to increase the Eu3+emission *** improvement might be attributed to the increase in the photoluminescent quantum yield originating from larger grain sizes and better crystallinity.A detailed analysis of the X-ray diffraction pattern and the asymmetric ratio estimated from the photoluminescence spectra show that the local lattice environment around Eu3+in GdNbO4does not change significantly with the codoping of Bi3+and Li+.Our results indicate that Li+doping is a promising way to improve the emission properties of rare-earth ion-doped GdNbO4phosphors.

Integrins are a highly complex family of receptors that, when expressed on the surface of cells, can mediate reciprocal cell-to-cell and cell-to-extracellular matrix(ECM) interactions leading to assembly of integrin adhesion complexes(IACs) that initiate many signaling functions both at the membrane and deeper within the cytoplasm to coordinate processes including cell adhesion, migration, proliferation, survival, differentiation, and metabolism. All metazoan organisms possess integrins, and it is generally agreed that integrins were associated with the evolution of multicellularity, being essential for the association of cells with their neighbors and surroundings, during embryonic development and many aspects of cellular and molecular biology. Integrins have important roles in many aspects of embryonic development, normal physiology, and disease processes with a multitude of functions discovered and elucidated for integrins that directly influence many areas of biology and medicine, including mammalian pregnancy, in particular implantation of the blastocyst to the uterine wall, subsequent placentation and conceptus(embryo/fetus and associated placental membranes) development. This review provides a succinct overview of integrin structure, ligand binding, and signaling followed with a concise overview of embryonic development, implantation, and early placentation in pigs, sheep, humans, and mice as an example for rodents. A brief timeline of the initial localization of integrin subunits to the uterine luminal epithelium(LE) and conceptus trophoblast is then presented, followed by sequential summaries of integrin expression and function during gestation in pigs, sheep, humans, and rodents. As appropriate for this journal, summaries of integrin expression and function during gestation in pigs and sheep are in depth, whereas summaries for humans and rodents are brief. Because similar models to those illustrated in Fig. 1, 2, 3, 4, 5 and 6 are present throughout the sc
