Development of the facility for model scramjet testing

A hypersonic propulsion test facility has been constructed in IMCAS (Institute of Mechanics, Chinese Academy of Sciences) in order to provide a high enthalpy hypersonic flow for a model scramjet testing. The vitiated air is produced by a hydrogen/air and oxygen replenishment combustion heater with flow rate of 3.5kg/s, total pressure of 5MPa and total temperature of 2000K in maximum, and accelerated up to Mach 5.6 by a two-dimensional nozzle. Test chamber of the facility is evacuated by a one-stage central air ejector. The preliminary facility performance tests showed that the vitiated air heater could provide the high enthalpy flow as expected. A copper model scramjet without cooling is ready for testing. © 2001 The American Institute of Aeronautics and Astronautics Inc. All rights reserved

promotion incentive、 land grant and environmental pollution

环境与发展的问题，一直是天平的两端。改革开放以来，我国的经济得到了跨越式的发展，但这种以牺牲生态环境为代价的粗放式发展的可持续性受到广泛质疑。随着生态破化的日趋严重化，政府到社会都在寻求增长与环保双轨并进的发展模式。本文基于2007年至2016年期间312个城市的官员、土地及环境污染数据，考察了官员的晋升激励及个人特征对官员辖区内土地出让的影响，并进一步讨论这种影响与地方环境污染之间的联系。 本文的第一部分说明了选题的背景及意义，并阐述了本文相较于以往文章的创新之处；第二部分对现有文献进行分类阐述和总结；第三部分构建了回归模型及并对数据搜集、选取进行说明；第四部分对实证结果进行展示和分析；第...The problem of environment and development has always been the ends of the balance.

The Impacts of Rent-Seeking on Firm Value and the Relevant Mechanisms: An Empirical Research on Chinese Listed Companies

改革开放近40年来，我国的经济社会发展取得了巨大的成就，但在法制建设及市场化建设等方面依旧存在一些问题，如政府与市场的边界划分不甚明确，政府在社会资源配置中依旧发挥着不可替代的作用，部分政府官员甚至滥用相关规定变相设租。在这种背景下，为了减少遭受政府的不公正待遇，以及获取对企业发展攸关的稀缺资源，企业热衷于向政府官员寻租。 寻租会对公司价值产生何种影响？它主要通过哪些路径影响了公司价值？在不同的内外部环境下寻租对公司的影响会不会有所不同？寻租对公司价值的长期影响与短期影响是否有所不同？本文将围绕上述问题进行展开。 本文以我国2009-2015年沪深两市A股上市公司为研究样本，运用多元线性回...Forty years of reforming and opening-up have witnessed great achievement in Chinese economy and society.
