We collected data on sleeping site use from 2.groups of white-headed langurs(Trachypithecus leucocephalus)living in Fusui Nature Reserve,china between August 2.07 and July *** information was used to test several hypotheses regarding ultimate causes of sleeping site use in this ***-headed langurs slept either in caves(17 sites)or on a cliff ledge(1 site).They used all sleeping sites repeatedly,and reused some of them on consecutive nights;3.nights was the longest consecutive use of any one sleep *** suggest that langurs use sleeping sites to make approach and attack by predators difficult,and to increase their own familiarity with a location so as to improve chances for ***’ cryptic behaviors with an increased level of vigilance before entering sleeping sites may also help in decreasing the possibility of detection by *** 1 spent more sleeping nights in the central area of their territory than expected;in contrast,group 2.spent more sleeping nights in the periphery of their territory,which overlaps with that of another groups,than *** position of sleeping site relative to the last feeding site of the day and the first feeding site of the subsequent morning indicated a strategy closer to that of a multiple central place forager than of a central place *** results suggest that territory defense and food access may play an important role in sleeping site use of white-headed langurs.

资源环境承载力状态评价研究成果众多,研究视角多侧重于"压力—状态—响应"模型的传统途径。本文构建了区域资源环境承载力综合评价框架体系,通过建立"PS-DR-DP"正六边形相互作用力理论模型,将资源环境承载力分解为"压力—支撑力""破坏力—恢复力""退化力—提升力"三对相互作用力,分别对应资源支撑能力、环境容量和风险灾害抵御能力,根据不同作用力大小变化所引起的六边形的形状和面积的变化综合测度区域资源环境承载力状态的变化。基于上述理论模型,采用分类排列多边形图示法,研究了北京市2.10-2.15年资源环境承载力状态的变化。结果表明,2.10-2.15年北京市资源环境承载力趋于理想承载状态。2.10年正向因子综合承载作用力与负向因子综合承载作用力的比值为1.0143.比值大于1,区域承载状态较好;而2.15年该比值为1.1411。与2.10年相比,2.15年北京市资源环境承载状态相对更佳。2.15年相比较于2.10年,负向因子作用力均减弱,正向因子综合作用力增强。2.15年人口规模为2.71万,承载贡献均值为0.702.,进入最佳承载门槛,且仍具有进一步承载的空间。研究结论对北京市2.2.年人口规模控制在2.0}0万以内提供了理论支撑。

Anodic aluminum oxide (AAO) tem- plates with various branched pores were prepared through one- to multi-step varying the anodic voltage by a factor of 1/ 2.during an anodization of alumi- num. The corresponding branched Fe nanowires (i.e. Y-branched, two-level branched and more complex tree-like nanostructures) were achieved by electrodepositing Fe into the branched pores of the AAO template. Selecting area electron diffraction and high-resolution TEM images show that the stem and branches of the branched Fe nanowires are single- crystalline with a face-centered cubic lattice. These branched Fe nanowires will be of great fundamental and practical significance.

A series of the copolymers of ethylene with 1-hexene （M1-M9） synthesized by metallocene catalyst Et[Ind]2.rC1JMAO was studied by differential scanning calorimetry and successive self-nucleation and annealing （SSA） thermal fractionation. The distribution of methylene sequence length （MSL） in the different copolymers was determined using the SSA method. The comonomer contents of samples M4 and M5 are 2.04 mol% and 2.78 mol%, respectively. Both M4 and M5 have low comonomer content and their MSL distribution profiles exhibit a monotonous increase trend with their MSL. The longest MSL of M5 is 167, and its corresponding molar percent is 43.95%, which is higher than that of M4. Moreover, the melting temperature （Tm） of M5 is also higher than that of M4. The comonomer contents of samples M7, M8, and M9 are 8.73.mol%, 14.18 mol% and 15.05 mol%, respectively. M7, M8, and M9 have high comonomer contents, and their MSL distribution profiles display unimodality. M7 has a lower peak value of 3. and a narrow MSL distribution, resulting in a Tm lower than that of M8 and M9. The MSL and its distribution are also key points that influence the melting behavior of copolymers. Sometimes, MSL and its distribution of copolymers have a greater impact on it than the total comonomer contents, which is different from traditional views.

There are two Paleotethyan volcanic arcs in the Sichuan-Yunnan-Tibet border area: the west one named the North Lancangjiang Arc, which was of Early Permian and was related to eastward subduction of the Bitu Ocean (a major Paleotethyan oceanic basin), and the east one the Haitong-Xuzhong Arc, which was of Late Permian to Early Triassic, recording the westward subduction of the southern segment of Jinshajiang Ocean (a branch Paleotethyan oceanic basin). In this paper, petrochemical evidence to support their existence is discussed, providing temporal-spatial constraints for making the Paleotethysides clear.
