中国乒乓球俱乐部超级联赛是在中国社会主义市场经济体制背景下推出的一项职业体育赛事,代表了国际乒乓球职业赛事的最高竞技水平,却还没有发展成为一个真正的市场化体育产品。政府及其相关部门控制乒超联赛的管理与运作,掌管绝大部分的经济来源,而大部分的俱乐部却难以吸引消费者、取得赞助、获得转播权和盈利。收集了3类信息资源:有关体育市场理论与实践的文献、乒超联赛主要利益相关者的访谈以及现场考察资料,用以鉴定主题和认定相关的3个受研究构面(市场划分、品牌与品牌价值、管理与政策)。这3个理论层面在制定预期的研究框架和指导乒超联赛重新定位中起着决定性作用。以深入现场的实际调查资料为主要依据,采用克雷斯韦尔的定性研究程序,对乒超联赛的管理和营销所面临的问题及挑战进行分析,并从多维视角和多元途径,对乒超联赛进行重新定位和包装产品提出合理对策与建议。

Lighting is crucial for portrait photography,yet the complex interactions between the skin and incident light are expensive to model computationally in graphics and difficult to reconstruct analytically via computer ***,to allow fast and controllable reflectance and lighting editing,we developed a physically based decomposition through deep learned priors from path-traced portrait *** approaches that used simplified material models or low-frequency or low-dynamic-range lighting struggled to model specular reflections or relight directly without intermediate ***,we estimate the surface normal,skin albedo and roughness,and high-frequency HDRI maps,and propose an architecture to estimate both diffuse and specular reflectance *** our experiments,we show that this approach can represent the true appearance function more effectively than simpler baseline methods,leading to better generalization and higher-quality editing.

During air injection into an oil reservoir, an oxidation reaction generates some heat to raise the reservoir temperature. When the reservoir temperature reaches an ignition temperature, spontaneous ignition occurs. There is a time delay from the injection to ignition. There are mixed results regarding the feasibility of spontaneous ignition in real-field projects and in laboratory experiments. No analytical model is available in the literature to estimate the oxidation time required to reach spontaneous ignition with heat *** paper discusses the feasibility of spontaneous ignition from theoretical points and experimental and field project observations. An analytical model considering heat loss is proposed. Analytical models with and without heat loss investigate the factors that affect spontaneous ignition. Based on the discussion and investigations, we find that it is more difficult for spontaneous ignition to occur in laboratory experiments than in oil reservoirs; spontaneous ignition is strongly affected by the initial reservoir temperature, oil activity, and heat loss; spontaneous ignition is only possible when the initial reservoir temperature is high, the oil oxidation rate is high, and the heat loss is low.
