浅谈小桥涵水毁形式分析及防治措施

小桥涵作为路桥工程的重要排水设施,特别是在山区公路水毁中,小桥涵占极大的比重。由于表现形式多样,影响因素繁杂,所以对排水造成了很大的影响。为了让小桥涵切实发挥作用,在排水的同时,起到抗洪能力,必须在小桥涵的水毁方面,做好防治工作。本文结合我国小桥涵水毁形式,对小桥涵水毁形式．设置要点以及防治方法进行了简要的探究和分析。

皖江城市带FDI影响因素分析

影响FDI的因素有市场因素、成本因素、集聚因素、创新因素等,从这些因素中选取市场规模、市场化程度、劳动力成本、基础设施、地区产业结构、非国有企业数量、人力资源8个指标,运用Matlab软件对皖江九市2002—2011年的数据进行多元回归分析。结果表明,市场规模、劳动力成本和地区产业结构是影响皖江城市带FDI的三大因素,认为政府应采取继续扩大市场规模、保持低劳动力成本优势、提高劳动者素质和产业聚集度等对策。     

沥青胶结料性能评价新指标的研究

针对中国常用的沥青高温指标和温度敏感性指标的不足,首先运用自行研发的稠度测试仪进行了沥青粘弹性分析,发现沥青粘性部分是影响沥青高温性能的关键,由此提出了沥青纯粘性稠度及其计算方法;与沥青混合料动稳定度的比较分析表明：纯粘性稠度克服了中国现有高温指标不适宜评价改性沥青的缺点,可以作为沥青的高温指标。然后,通过稠度与温度关系的分析,提出了表征沥青感温性的稠度－温度指数及其计算方法。最后,给出了沥青纯粘性稠度和稠度－温度指数标准的建议值。

Deep structure at northern margin of Tarim Basin

In this paper, a 2D velocity structure of the crust and the upper mantle of the northern margin of the Tarim Basin （TB） has been obtained by ray tracing and theoretical seismogram calculation under the condition of 2D lateral inhomogeneous medium using the data of seismic wide angle reflection/refraction profile from Baicheng to Da Qaidam crossing the Kuqa Depression （KD） and Tabei Uplift （TU）. And along the Baicheng to Da Qaidam profile, 4 of the 10 shot points are located in the northern margin of the TB. The results show that the character of the crust is uniform on the whole between the KD and TU, but the depth of the layers, thickness of the crust and the velocity obviously vary along the profile. Thereinto, the variation of the crust thickness mainly occurs in the middle and lower crust. The Moho has an uplifting trend near the Baicheng shot point in KD and Luntai shot point in TU, and the thickness of the crust reduces to 42 km and 47 km in these two areas, respectively. The transition zone between the KD and TU has a thickest crust, up to 52 km. In this transition zone, there are high velocity anoma- lies in the upper crust, and low velocity anomalies in the lower crust, these velocity anomalies zone is near vertical, and the sediment above them is thicker than the other areas. According to the velocity distributions, the profile can be divided into three sections： KD, TU and transition zone between them. Each section has a special velocity structural feature, the form of the crystalline basement and the relationship between the deep structure and the shallow one. The differences of velocity and tectonic between eastern and western profile in the northern margin of the Tarim Basin （NMTB） may suggest different speed and intensity of the subduction from the Tarim basin to the Tianshan orogenic belt （TOB）.     

人力资本与区域经济增长的相关性分析

西方学者的研究表明:"人力资本是经济增长的重要源泉。"新疆作为我国西部一个偏远落后的地区,它的人力资本发展状况如何?它能否起到推动经济增长的作用?本文通过定量分析得出了新疆人力资本对经济增长的拉动作用较弱的结论,进而找出了影响新疆人力资本发展的原因,最后提出了对其他落后地区人力资本发展的启示。     

社会保障政策对经济发展的影响

完善的社会保障制度是建立社会主义市场经济体制的前提和保证。我国现行社会保障制度具有因地制宜、先易后难、不断转换的特点。目前我国社会保障政策存在不统一、强制性差、调剂性差、增值困难等主要问题。目前的这种社会保障政策对经济发展产生了一定的负面影响。要力争通过切实保障农民的利益、正确处理好各群体之间的权力与责任、做好就业保障工作来建立更好的社会保障模式。

Relationships of Aegilops tauschii revealed by DNA fingerprints: the evidence for agriculture exchange between China and the West

Genetic diversity and relationships of wild goat grass (Aegilops tauschii Cosson) from Iran and Xinjiang, west China, as well as its weedy type from the Yellow River region of Shaanxi and Henan provinces in China were analyzed by simple sequence repeat (SSR) fingerprinting. A high level of genetic diversity in Aegilops tauschii accessions from Iran was observed, and the richness of genetic diversity was followed by accessions from Shaanxi, Henan, and Xinjiang. The weedy type of Aegilops tauschii showed a close genetic relationship with the wild type from different regions in Iran. The results indicated that the weedy Aegilops tauschii found in the Yellow River region was most likely introduced from Iran—the diversity center of Aegilops tauschii. The weedy Aegilops tauschii populations found in the Yellow River region may be brought into the central part of China as a weed species together with common wheat (Triticum aestivum L.) from the west during various periods of time in history. This finding has provided strong evidence for the introduction of common wheat from the West into China via the Silk Road, and also demonstrated the important role of the Silk Road in the exchange of agriculture and other relevant technologies between China and the West.
