干湿循环作用下红黏土裂隙发育试验研究

对江西红黏土路基填料进行干湿循环试验,比较不同压实度的红黏土试样在干湿循环作用下的裂隙发育情况。试验所用红黏土在最优含水率附近,力学性质较好,即使压实度降低到87%,依然能满足抗剪强度和压缩性要求。同时考虑规范对于最低压实度的要求,对压实度为90%和93%的试样进行干湿循环试验。结果表明：在经过6次干湿循环作用后,90%和93%的试样均产生明显的裂隙;93%压实度的土样,相比90%压实度的土样,裂隙发育宽度更细,网状裂隙包裹的土块面积大,边缘土体跌落少,完整性更好;但提高压实度不能防止裂隙的发育,只能抑制裂隙的进一步发育。试验结果可为研究红黏土作为路基填料在干湿循环作用下的路用性能提供依据。     

内踝的应用解剖及临床意义研究

踝部面积小而受力较大,所以踝部骨折是常见的骨折之一。人体内踝缺乏公认的标准,内踝骨折手术在很大程度上是凭经验进行,从而带来了创伤性关节炎等风险。本文通过实验测量人体内踝角及其相关的数值,从而有效指导内踝骨折手术及定位导向器的设计,具有重要的临床意义。     

压裂液返排的数值模型优化

压裂液返排对压裂施工的效果影响重大,目前我国在压裂液返排的建模方面主要是针对常规砂岩储层,由于模型的复杂程度被简化,计算结果易出现误差而偏离实际。本文根据流体的质量守恒定律和裂缝形态变化规律对压裂液返排数值模型进行优化,并利用体积平衡原理求解该模型,通过压力变化对裂缝闭合时间给出定量判断,为后续放喷油嘴时的尺寸选择提供理论依据。     

螺旋CT及后处理技术在肩胛骨隐匿性骨折中的诊断价值

目的探讨螺旋CT及后处理技术在临床上对肩关节隐匿性骨折的诊断价值。方法回顾性分析2012年7月至2014年6月来我院检查的137例肩关节外伤患者,对比普通X线检查及CT扫描结果。结果 62例X线摄片未见确切骨折患者,通过CT扫描后并进行后处理技术诊断27例骨折。结论螺旋CT扫描及进行图像后处理分析可以提供更为直观、准确的整体骨骼显示情况,从而提高外伤及急诊患者影像诊断准确率,减少特殊部位及重叠骨骼骨折漏诊等情况,从而为人民群众提供更为满意的医疗服务。     

Resort Morphology Research: History and Future Perspectives

This paper adopts a geographical perspective to understand the conceptual and theoretical issues of resort morphology. Resort morphology refers to “the forms and associated functions of a destination area and their development”. Resort towns are differentiated from other urban areas in terms of morphology because of their functional emphasis on tourism. The literature reflects the significant interest of European geographers in the morphological study of coastal resort towns. However, limited attention has been given to resort morphology in developing countries, including those in Asia. It is argued that the complex of contextual factors that influence the morphological character of resorts needs to be considered and, furthermore, there is a great need to develop a systematic approach for investigating resort morphology. Although the morphological approach to the study of resorts is transferable, it is likely that Asian morphologies will differ from their western counterparts because of their time, scale and pace of development.     

油井压裂选井方法在C油田中的应用

随着油田的不断深入开发,压裂改造是油藏开发获取工业油流的必须手段。为确保油井压裂的效果与经济效益,提升油井压裂方案的符合率,避免传统上压裂选井的经验性与盲目性,依据近些年来压裂选井的实践,应用模糊数学分析的方法,建立了适合C油田的压裂选井方法,即模糊评判分析方法。通过对模型进行实际运算应用,其结果与该地区实际压裂的施工结果具有很好的符合性。研究成果为C油田可持续开发奠定基础,对于指导油田压裂选井工作具有重要意义。     

回归价值原态：“劳动价值论”之争的哲学解决

“劳动价值论”在马克思批判资本主义制度时才有其“政治意义”,置放于现代社会主义社会中,其“政治意义”自然消解。而从哲学的立场或用哲学的思维和方法来解决关于“劳动价值论”的纷争,就会正好看到:“价值”的真实形态本来就是“使用价值”,“劳动”的真实形态本来就是“具体劳动”。因而,所谓“使用价值和抽象价值”、“具体劳动和抽象劳动”在其经济意义上就成为了“假问题”,而围绕“假问题”的所有争论将毫无意义。哲学视域中的“劳动价值论”要着力表明的结论是:所有参与创造“使用价值”的“要素”在价值财富的创造和分配中都具有公平的地位;所有参与“具体劳动”的“要素”在劳动财富的创造和分配中都具有公平的地位。新的经济制度应在此意义上而创新。     

火星大道浏阳河大桥岩溶成因及分布规律

勘察中发现,浏阳河大桥桥位地质条件复杂,岩溶发育,但相距桥位上游约2km和下游约1km的已建桥位处地质条件较好。文章对此从地质、构造、岩石特性等方面分析了该桥位处岩溶成因及分布规律。     

Short reports

The aim of the study was to evaluate a hospital-based injury recording system on hip fracture registration in elderly persons aged + 65 years from 1994 through 2008, and to examine the agreement between the number of validated fractures and the number of fractures reported to the Norwegian Patient Registry using three different sources: (1) Medical records, (2) Patient administrative system and (3) The hospital's hip fracture record to the Norwegian Patient Registry from 2002 through 2008. The injury recording system included 582 hip fracture events and 535 (92%) were confirmed through the medical records. Reasons for non-verification were different coding failures. Searching the patient administrative system using ICD codes identified 16 hip fractures not included in the fracture registry between 2002 through 2008. The total number was the same as the number of hip fractures reported to the Norwegian Patient Registry using ICD codes alone for identification. The conclusion is that on well-defined diagnosis like hip fractures, local fracture registries may obtain a high degree of reliability if different sources are available for quality control. Well-functioning patient administrative systems may be used to study numbers of hip fractures.
