兴起于美国的信息技术革命是一种精英化技术路线,研发及其产品应用不以满足广大劳动人群以及制造业等实体产业的发展需求为目的,目前成为美国国内发展不均衡的原因之一。在我国,发展壮大数字经济是在加快解决发展不平衡不充分问题,分阶段促进共同富裕的战略理念下得以强调的,要求建设“人人参与的发展环境”,因此有必要在理念上明确技术路线的可选择性,激励探索不同于精英化取向的技术方案。实践中已出现某些非精英化路线的范例,其理论意义和政策意义值得发掘。

我国当前的分散化政务数据管理结构,一方面隐藏着阻碍数据开放共享和难以实施监督的缺点,另一方面又具有专业性和数据处理能力强的优点。各国实践表明,利用分散化网点收集超大规模数据的模式,正凸显其重要性。因此,不宜简单否定我国当前的数据管理结构,但需要思考如何克服其内在缺陷。流行的数据产权化管理思路不足以促进大数据发展。本文综合运用财产规则和责任规则,建立一个有助于多元主体协同共享政务数据效益的"三-二-四"型数据管理机制,通过开放责任的设置和合法权益的保护来激励不同主体共同参与推进政务大数据的可持续性开放共享。

人工智能的兴起不仅是技术或产业领域的重大发展,更是经济、社会、政治各领域的基础性和综合性变革,由此产生的治理挑战要求公共政策框架的重构与创新,而这又体现为三个基本问题。首先在技术层面,人工智能的核心是算法与数据,其内在逻辑是基于机器学习形成自主决策。其次,传统科层治理结构、方法以及范围不能应对新的变化,从而构成了人工智能时代的治理挑战。各国现有政策所遵循的"无需批准式监管"或"审慎监管"逻辑固然有其合理性,但却局限于"创新"与"安全"的二维选择而失于片面。最后,本文提出综合性公共政策框架,力图为人工智能时代的崛起建立制度基石。

为了研究水涡轮尾水管的涡带特性与Omega涡识别方法对尾水管涡带的识别效果,对比了Q准则和λ_(2)准则以及Omega涡识别方法对尾水管涡带的识别效果,并基于Omega方法和降维的Omega方法分析了不同工况下尾水管的涡带特性.结果表明:对于径流式水涡轮,通过合理调整阈值,Q准则和λ_(2)准则以及Omega涡识别方法均能识别到清晰合理的尾水管涡结构,而Omega方法阈值选取区间较小且具有不敏感性;水涡轮尾水管在小流量工况时会出现较长的涡带,不利于机械的稳定性.同时运用二维Omega涡识别方法与拟涡能指标,在不同工况下对尾水管各监测面进行定量分析,确定涡量浓度高的区域,研究尾水管的能量耗散规律.结果发现,尾水管进水口到弯管之间的区域涡量浓度最高,能量耗散最大,流态最不稳定,这可为该型式水涡轮的结构优化提供理论参考与数据支撑.
