中部地区县域民营经济发展研究——以湖南省为例

县域经济是国民经济的基本单元,民营经济是县域经济的主导经济。自改革开放以来,我国民营经济经历了从无到有、从小到大、由弱到强的发展历程。目前,我国中部地区县域民营经济发展存在观念意识淡薄、融资渠道不畅、专业人才缺乏、管理制度落后等问题,应通过解放思想、更新观念、拓宽融资渠道、强化企业内部管理等方式,促进县域民营经济的持续、健康、稳定发展。     

三年上水平进程中廊坊市夜经济发展路径研究

2010年河北省召开了发展夜经济工作会议,把提高夜消费水平、做强夜经济作为当前扩大内需的一项重要工作来抓。夜经济是城市经济发展到特定阶段的反映,夜经济已成为一个城乡经济框架中的重要组成部分。在城镇建设三年上水平进程中,廊坊市城镇建设已经开始进入系统提升城市功能和品质,塑造城市特色上水平、出品位、生财富阶段。如何让夜经济发展成为廊坊市三年上水平进程中的有力推动者,本文就这一问题展开研究,进而提出相应的建议。

Prioritizing scientific exploration: A comparison of the ethical justifications for space development and for space science

I argue that the moral justification for space science is more compelling than the moral justification for space development. Thus, we ought to reemphasize the status of science as a major stakeholder in space, especially when entertaining policies which might encourage the kinds of space development activities (e.g. resource exploitation) that are liable to conflict with the scientific uses of space.     

外语教学中情商的培养与发展

情感智商，简称情商，对语言学习的过程与结果有直接影响。21世纪是一个综合国力与高素质人才相互竞争的时代，英语教学的质量面临着挑战，把EQ理论引入英语教学实践对提高英语教学质量具有现实意义。在英语课堂教学中只有了解、重视和培养学生的情商，才能真正做到因材施教，把握信息输入与输出的最佳时机，同时帮助学生摒弃不良的学习情绪，调整学习方法以形成良好的学习习惯。

End-to-end validation process for the INTA-Nanosat-1B Attitude Control System

This paper describes the end-to-end validation process for the Attitude Control Subsystem (ACS) of the satellite INTA-NanoSat-1B (NS-1B). This satellite was launched on July 2009 and it has been fully operative since then. The development of its ACS modules required an exhaustive integration and a system-level validation program. Some of the tests were centred on the validation of the drivers of sensors and actuators and were carried out over the flying model of the satellite. Others, more complex, constituted end-to-end tests where the concurrency of modules, the real-time control requirements and even the well-formedness of the telemetry data were verified. This work presents an incremental and highly automatised way for performing the ACS validation program based on two development suites and an end-to-end validation environment. The validation environment combines a Flat Satellite (FlatSat) configuration and a real-time emulator working in closed-loop. The FlatSat is built using the NS-1B Qualification Model (QM) hardware and it can run a complete version of the on-board software with the ACS modules fully integrated. The real-time emulator, running on an industrial PC, samples the actuation signals and emulates the sensors signals to close the control loop with the FlatSat. This validation environment constitutes a low-cost alternative to the classical three axes tilt table, with the advantage of being easily configured for working under specific orbit conditions, in accordance with any of the selected tests. The approach has been successfully applied to the NS-1B in order to verify different ACS modes under multiple orbit scenarios, providing an exhaustive coverage and reducing the risk of eventual errors during the satellite's lifetime. The strategy was applied also during the validation of the maintenance and reconfiguration procedures required once the satellite was launched. This paper describes in detail the complete ACS validation process that was performed and it shows the most relevant errors detected and fixed during testing. Finally it summarises some of the most significant conclusions.
