洛阳铲桩基的质量控制

机动洛阳铲是一种比较落后的桩基施工方式,但因其经济、施工灵活和方便而被广泛采用,尤其在低层住宅和房地产公司投资开发的住宅中。洛阳铲由于本身工艺的落后性,怎样控制它的质量成为洛阳铲的施工关键。根据本人的施工经验,谈谈怎样控制洛阳铲的质量。1　设计上控制规范规定洛阳铲的垂直度不得超过1/100L(L为桩身长),但实际施工过程中,垂直度不易控制,不论是梅花桩还是双排桩,建议都采用偏心受压公式:n≥μF GR,而不采用中心受压公式:n≥F GR。式中:F——作用在桩基上的竖向荷载设计值(kN)G——桩基承台和承台上的土受到的重力(kN)n—…     

Iceland,Small Country Witnessing Diversified H.E.Mr,Cooperation with China——Interview with Ambassador of Iceland H.E.Mr.Gunnar Snorri Gunnarsson

Located in the North Europe,Iceland is a very beautiful country. Although very small with an area of 103,000 sq.km and a population of 308,000, and quite different in most respects such as geographical location,size,history,climate and political structures,it has developed very good relations with China.For in- stance,Iceland was the first European coun- try to recognize China as a market economy. In many areas such as trade,investment, industrial cooperation,from fishing,food processing,tourism,information technol- ogy,geothermal,finance,etc.,Iceland has made pragmatic activities,for instance,last summer Icelandic and Chinese authorities concluded a feasibility study on negotiating Free Trade Agreement;in June an Iceland Business Forum was held,which groups to- gether over twenty Icelandic companies that have established offices in China;etc. In July,China's Foreign Trade inter- viewed H.E.Mr.Gunnar Snorri Gunnars- son,Ambassador of Iceland in Beijing. According to him,Iceland has developed diversified and active economic and trade cooperation with China in many areas.The following is a written interview with Mr. Gunnar Snorri Gunnarsson.     

基于资产保值增值的国企审计和巡视频度安排与协同

选取央企控股的A股上市公司为样本,实证检验政府审计和党委巡视频度及其协同对国企资产保值增值的影响机理。研究发现,在一届政府任期（五年）内,相较于没有或二次被政府审计或党委巡视的国企,被审计或巡视一次更能有效促进国企资产保值增值;政府审计与党委巡视实施时间间隔24个月以上,督促国企资产保值增值效果更佳。研究结论对于合理安排国企的政府审计与党委巡视频度以及协同时机,实现国企审计监督全覆盖,提高党委巡视效率,构建高效的政府审计与党委巡视协同机制,促进国企资产保值增值具有启示意义。     

环保阻燃剂对涤纶织物阻燃性能的研究

本论文分别采用环化磷酸酯和十溴二苯乙烷两种阻燃剂对纯涤纶织物阻燃整理。采用极限氧指数仪、垂直燃烧测定仪和锥形量热仪分别对整理后涤纶织物的阻燃性能进行研究。研究结果表明,两种阻燃剂均能够改善涤纶织物的阻燃性能,阻燃性能均能达到GB 20286-2006标准中的阻燃B1级。阻燃整理后,涤纶织物的断裂强力没有受到明显影响。     

人口规模、创新投入与全要素生产率——基于京津冀13个地级市的实证分析

摘要：运用SBM-ML方法测算城市全要素生产率,构建动态面板模型,以探究京津冀地区人口规模、创新投入与城市全要素生产率之间的关系。结果显示：京津冀地区全要素生产率小幅上涨,技术效率和技术进步拉动作用明显。常住人口规模对提升城市全要素生产率的促进作用不明显;人才集聚对城市全要素生产率的提升具有显著的正向效应;政府创新投入与城市技术进步指数呈非线性的倒U型关系,表明政府短期投资能促进城市科技创新,长期投资会对城市发展产生挤出效应。     

政府审计能提升国有企业并购重组业绩承诺可靠性吗？——基于审计署央企审计结果公告的经验证据

以我国沪深A股中央国有上市公司2012—2020年的数据为样本,将审计署实施的审计监管事件作为一个准自然实验,利用多时点双重差分模型实证检验政府审计对国有企业并购和重大资产重组中业绩承诺可靠性的影响和作用机制。研究发现：（1）政府审计的实施能够显著提升国有企业并购重组业绩承诺的可靠性水平,这一结论在全部并购重组样本中和剔除业绩达标在5%以内的样本后均得到了有效验证,且经过多种稳健性和内生性检验后依然成立;（2）进一步的机制检验结果表明,政府审计能够通过“监督”效应和“增量”效应促进国企并购重组业绩承诺可靠性的提升,但并没有对未接受审计的同行业企业起到很好的“溢出”效应;（3）在业绩承诺到期后的经济后果上,政府审计显著提升了业绩承诺达标企业的长期绩效表现,同时降低了其商誉减值风险,但对于业绩承诺未达标企业的影响效果并不明显。     

AZ91D镁合金激光熔化成型工艺参数优化

为了对AZ91D镁合金粉末激光熔化成型工艺参数进行优化分析,运用正交试验和极差分析方法对激光功率、扫描速度、扫描间距3个关键工艺参数对制件力学性能的影响规律进行成型工艺研究,对优化参数后的试件进行固溶处理,并结合X射线衍射与金相测试进行微观组织分析。结果表明:AZ91D镁合金的选区激光熔化成型优选工艺参数为激光功率180 W,扫描速度500mm/s,扫描间距60μm;使用该优化工艺参数打印的试件性能为致密度99.8%,屈服强度200MPa,抗拉强度285 MPa,延伸率3.2%,维氏硬度135Hv;试件的优化热处理方案为420℃×12h固溶处理,该工艺可大幅提升试样的延伸率,使其增长至5.9%。该工艺对航空航天等产品轻量化要求较高的领域具有重要的意义。
