农村基层选举中存在的问题

当前农村基层选举中出现了下述问题：部分乡镇干部成功为选举的阻力,在选举过程中不按法律程序办事,如何纠正他们的错误行为尚没有规章可依,村委会与居委会纠缠不清带来选举难题,农村家庭势力与农民自身素质,时间安排的不当等因素也影响和制约着基层选举公正有效地进行。

1　 Agency TheoryAn agency relationship is presentwheneverone party delegates anotherparty to undertakesome action on the former′s behalf. Examplesof agency are universal,including employer-employees,lawyer-client,buyer-supplier,etc. Agency problem occurs in such arelationship because of informational asymmetry and goal conflictdue to differentattitudestoward risk between the principal and the agent.

冰乙酸与硬脂酸组分钛基脂的制备及性能研究

采用实验室制脂釜制备出冰乙酸与硬脂酸组分钛基脂,考察了冰乙酸与硬脂酸组分钛基脂的物理和摩擦学性能,阐述了钛基脂皂分子的形成机制。利用红外光谱表征了钛基脂皂分子结构,利用滴点仪和锥入度仪测试了钛基脂的物理性能,并用四球试验机评价了钛基脂的摩擦学性能。结果表明,冰乙酸与硬脂酸组分钛基脂的合成生成了—COOTi—和Ti—O键,形成了碱式双酸钛皂。制备的冰乙酸硬脂酸组分钛基脂属于1号脂,滴点达到255℃,并具有优良的摩擦学性能。     

盐酸浸泡后的铁在空气中氧化及缓蚀剂防护作用的穆斯堡尔谱研究

用内转换电子穆斯堡尔谱(CEMS)分析了铁经盐酸或加有缓蚀剂的盐酸(缓蚀盐酸)浸泡后在空气中的氧化物,以及盐酸中的缓蚀剂对浸泡后铁在空气中氧化的防护作用.结果表明,盐酸或缓蚀盐酸浸泡后的铁在空气中的氧化物主要是γ-FeOOH,有少量β-FeOOH;盐酸中缓蚀剂对浸泡后的铁在空气中氧化具有防护作用.而且在盐酸中对铁的缓蚀性能较好,在空气中对铁的防氧化性能也较好.最后对缓蚀剂的防氧化作用机理进行了讨论.     

SU（2）格点规范理论的正切作用量的改进变分法研究

利用改进变分法求出了正切作用量的四维SU_(2)格点规范理论的元格内能和比热曲线.发现元格内能曲线是连续的,理论有禁闭倾向;比热峰βc=1.95,这比平均场方法的结果(βc=2.05)更接近于Shahbazyan方法的结果(βc=1.82).
