[ Objective] The research aimed to study change characteristics and formation cause of summer precipitation abnormality in Loess Plateau of northern Shaanxi Province. [ Method] Based on summer precipitation data at 15 observation stations in Loess Plateau of northern Shaanxi Province and NCEP/NCAR dataset from 1961 to 2008, change characteristics of summer precipitation in the region were investigated by using linear trend estimation and composite analysis. [Result] Summer rainfall had decrease trend in most parts of northem Shaanxi Province, but had increase trend in western and southern regions. The interannual and interdecadal variations were obvious. It had a large amount of precipitation from the mid- 1970s to the mid-1990s, while summer rainfall had decrease trend after the mid-1990s and increase trend in recent years. In wet years, it was a large positive anomaly zone from western Ural Mountains to northem Lake Baikal at middle and high latitudes, indicating that there was a blocking high over the Ural Mountains, while it was negative anomaly zone from northern Okhotsk Sea to Lake Baikal. From Northwest Pacific Ocean to Bo- hal Sea Bay and North China, it was a wide range of significant positive anomaly zone, which was favorable for Westem Pacific subtropical high ex- tending westward and northward. The analysis in dry years showed opposite circulation configuration. It was ＂ -, ＋, -＂ wave train distribution in middle and high latitudes and positive anomaly zone along the Sea of Okhotsk. Western Pacific subtropical high was also by south and east. Major water vapor was from southeast direction in wet years, and abundant water vapor caused more summer rainfall in northern Shaanxi. In dry years, water vapor was from westerly tuming southerly flow. It was weaker and by east. [ Conclusion] The research provided reference for reasonable utilization of summer precipitation in the zone.

在水库开闸泻水过程中,高速水流掺气以及消能过程中水流的强烈碰撞会卷吸大量气体形成溶解气体过饱和现象,进而引起鱼类患气泡病死亡。此文引入气体向气泡界面和水体表面传质的机理,利用坐标变换对自由水表面边界进行特殊处理,在三维紊流两相流模型的基础上模拟气泡在水中的运动和溶解,从而计算过饱和气体的浓度分布,并将此模型运用在对葛洲坝饱和气体模拟预测中,还和实测值进行了比较。结果表明:运用坐标变换方法后的模型能更准确地模拟饱和气体浓度。

为探析声誉对公私合作(PPP)项目监管的影响,构建了演化博弈模型,分析了声誉对私人部门及政府监管部门行为的影响.结果显示,在未考虑声誉的情形下,当政府监管部门的监管收益不足以弥补监管成本时,由于受到私人部门寻租行为及对私人部门的惩罚不足的影响,系统最终可能演化为私人部门选择提供低质量公共产品/服务的稳定状态;在考虑声誉的情形下,当声誉转化水平达到一定程度时,可以有效促进私人部门自觉提供高质量的公共产品/服务.研究结果表明,政府在制定相应监管与惩罚机制的基础上,还应建立合理的声誉机制以激励私人部门不断提高公共产品/服务的质量.

大学、产业和政府通过互动自反的逐级推进形成开放、协同创新效用;大学专利技术转移组织(TTO)通过改变信息传递结构、重复博弈和社会资本的粘合,降低交易成本以促进大学技术转移。基于刺激反馈和系统理论,三螺旋模式和TTO存在"三螺旋环境-TTO行为-绩效"互动关系,这三方面的内容最终成为TTO构建的框架模型基础。基于理论框架,我国TTO的构建首先要着眼于大学、产业和政府的互动自反建设,其次是TTO内部有效的运营。

According to the construction principle of B-spline, a formula of surface construction for airfoil blade with the given points has been derived. Meanwhile, the surface construction system for airfoil blade in practice as well as menus for the system have been constructed with the help of the commercial software (AutoCAD R14). The result in this paper is helpful for CAD/CAM of airfoil blades.
