Two lacustrine sporopollen records obtained from the Qaidam Basin (in the non-monsoonal region) and the Linxia Basin (in the monsoonal transition zone) indicate that during the early Pleistocene open forest-steppe/steppe vegetation developed in the Qaidam Basin, while in the Linxia Basin an open cypress forest-steppe shifted to a conifer/conifer-steppe and then to open forest-steppe vegetation. Existing sporopollen records from the Chinese Loess Plateau (CLP) (in the monsoonal region) indicate that around the Sanmen Paleolake open forest-steppe shifted to pine/conifer-broadleaved mixed forest. The conifer cover then changed to a subtropical evergreen broadleaved forest distributed around the Nihewan Paleolake. These changes suggest that wetter conditions progressed from western China to the east, and the climate became more humid than that of today indicating a stronger Asian summer monsoon during the early Pleistocene.

作者： ZHANG Zhiqin HE Xinwei SHANG Yongjia YU Zhiyu WANG Sufan wu fuli Key Laboratory of Functional Molecular Solids Ministry of Education Anhui Key Laboratory of Molecule-based Materials College of Chemistry and Materials Science Anhui Normal University Wuhu 241000 P R. China

In this paper, a novel compound 3-（2-qninolyl）-5-ferrocenyl-isoxazole（5） with high selectivity toward Cu2＋ over other heavy and transition-metal（HTM） ions was designed and synthesized in good yields. The compound not only could be used as an electrochemical probe for Cu2＋ with an anodic peak shift of Fe（II）/Fe（III） redox couple, but also could be a colorimetric and fluorescent probe due to the detectable change in color by naked eyes and a significant fluorescence quenching of monomeric anthracene moiety. This highly selective sensing of Cu2＋ may be attributed to the unprecedented intermolecular electron-transfer reorganization after the oxidation of the first single electron of compound 5, as indicated by electrospray ionization mass spectrometry（ESI-MS） and density functional theory（DFT） calculation results. To the best of our knowledge, this class of compounds have rarely been reported in the field of molecular sensing. It may have a potential significance for the application of the ferrocenyl-isoxazole derivative in molecular recognition.

The Eocene palaeovegetation landscape and palaeoclimate reconstructed from the pollen records in the Jiuquan Basin, northwest China provide some important information on the early uplift of the Tibetan Plateau and the origin and evolution of the aridification in northwest China. The records show the arid-semiarid scrubs with open forest palynofloras controlled by the subtropical high existed in northwest China during the 40.2-33.4 Ma. Four pollen assemblages are found: Nitrariadites-Cheno-podipollis-Pinaceae assemblage (40.2-37.9 Ma) is followed by Chenopodipollis-Nitrariadites assemblage (37.9-34.6 Ma), Pinuspollenites & Abietineaepollenites-Chenopodipollis assemblage (34.6-33.9 Ma), and Chenopodipollis-Nitrariadites assemblage (33.9-33.4 Ma). The percentage of thermophilic types is in anti-correlation with that of the dry types, which means the palaeoclimate is relatively warmwet or cold-dry during most of that time. Such aridity may be related to the water vapor reduction and the planetary wind system movement northward in response to the cooling caused by small-ephemeral icesheets.

所谓过失危险犯,是指以行为人过失实施的严重危险行为造成的危险结果作为犯罪构成必要条件的犯罪.作为过失犯与危险犯的有机结合,过失危险犯具有以下两个特征:一是过失危险犯在主观方面表现为过失,即行为人应当预见自己的行为可能发生严重危险结果因为疏忽而没有预见或已经预见而轻信能够避免,以致这种严重危险结果发生的心理态度.二是过失危险犯在客观方面表现为因行为人的过失行为导致了法律规定的严重危险结果的发生.这种危险结果一般发生在危害公共安全领域,而且具有现实可能性.

针对修改传输函数或者使用特殊的光照效果时不能完全解决直接体绘制医学数据人体组织间的遮挡问题,提出一种基于成员体关系的分层剥离体绘制算法.利用梯度阈值函数判断采样点的类型,通过采样光线获得同种组织的标量值范围;用由移动最小二乘法按照拟合出的不同组织的分界标量值和空间位置来建立每个体素的成员体关系;将成员体关系用于分层剥离体绘制,以解决同类组织的遮挡问题,并采用自适应的光线投射算法提高图像的绘制效果和速度.实验结果表明,文中算法可以根据医学数据来确定相应的成员体关系,使被遮挡部分绘制效果清晰.
