国有企业改制中收入激励的帕累托最优标准

收入对职工具有最直接的激励作用，而这一作用的保持与增强则取决于收入分配的科学性与合理性。国有企业正值改制时期，急需建立激励机制，制定科学合理的收入分配方案。综观国内外研究现状．企业职工的收入分配在实践中的标准是多样的，行动是盲目的。因此，探讨具有坚实经济理论支持的判断企业职工收入分配科学合理与否的理论标准，具有十分重要的意义。     

GRB observed by IBIS/PICsIT in the MeV energy range

We present the preliminary results of a systematic search for GRB and other transients in the publicly available data for the IBIS/PICsIT (0.2–10 MeV) detector on board INTEGRAL. Lightcurves in 2–8 energy bands with time resolution from 1 to 62.5 ms have been collected and an analysis of spectral and temporal characteristics has been performed. This is the nucleus of a forthcoming first catalog of GRB observed by PICsIT.     

Formation of Giant Planets– An Attempt in Matching Observational Constraints

We present models of giant planet formation, taking into account migration and disk viscous evolution. We show that migration can significantly reduce the formation timescale bringing it in good agreement with typical observed disk lifetimes. We then present a model that produces a planet whose current location, core mass and total mass are comparable with the one of Jupiter. For this model, we calculate the enrichments in volatiles and compare them with the one measured by the Galileo probe. We show that our models can reproduce both the measured atmosphere enrichments and the constraints derived by Guillot et al. (2004), if we assume the accretion of planetesimals with ices/rocks ratio equal to 4, and that a substantial amount of CO₂ was present in vapor phase in the solar nebula, in agreement with ISM measurements.     

Line blanketed non-LTE atmosphere models for Wolf-Rayet stars

A standard non-LTE Wolf-Rayet star atmosphere model is compared with an identical model but including line-blanketing. The structures of the two models are presented in detail and the implications of blanketed models for spectroscopic analyses are discussed.

晚清修律对封建正统法律思想的改易

自汉朝以来，以儒家法律思想为主的封建正统法律思想在中国法律史上一直处于独尊独尚的地位。然而，清廷统治的最后十年，一场史无前例的变法修律，却首开吸收西方资产阶级法律思想入律之先河，第一次对封建正统法律思想的根本原则，基本内容等进行了突破、改易。尽管这些突破是有限的，但它足以表明晚清修律终于结束了两千多年来封建正统法律思想的垄断统治，终于使中国古代法律冲破了旧的樊篱，迈上了近现代型的历史轨道，为新的法律思想的发展完善开拓出了广阔的空间。

无人机空中加油自主会合制导律研究

典型的自主会合制导律主要包括基于在线估计的制导律和无需在线估计的制导律两大类,其中在线估计具有计算量大,实现复杂的缺点。提出了一种无需在线估计的制导律,在此基础上,文章进行了改善,一是借鉴导弹中的带落角约束的比例导引律,实现了一种同时满足航向和纵向自主会合要求的制导律形式,简化了制导律设计;二是引入了相对距离反馈与速度反馈进行相对距离控制,避免了速度控制指令设计的复杂化和开环控制鲁棒性差的缺点。最后,通过一个仿真例子证明了这种制导律方案原理可行,具有一定的工程应用价值。     

The Seed Population for Energetic Particles Accelerated by CME-Driven Shocks

Understanding properties of solar energetic particle (SEP) events associated with coronal mass ejections has been identified as a key problem in solar-terrestrial physics. Although recent CME shock acceleration models are highly promising, detailed agreement between theoretical predictions and observations has remained elusive. Recent observations from ACE have shown substantial enrichments in the abundances of ³He and He⁺ ions which are extremely rare in the thermal solar wind plasma. Consequently, these ions act as tracers of their source material, i.e., ³He ions are flare suprathermals and He⁺ ions are interstellar pickup ions. The average heavy ion composition also exhibits unsystematic differences when compared with the solar wind values, but correlates significantly with the ambient suprathermal material abundances. Taken together these results provide compelling evidence that CME-driven shocks draw their source material from the ubiquitous but largely unexplored suprathermal tail rather than from the more abundant solar wind peak. However, the suprathermal energy regime has many more contributors and exhibits much larger variability than the solar wind, and as such needs to be investigated more thoroughly. Answers to fundamental new questions regarding the preferred injection of the suprathermal ions, the spatial and temporal dependence of the various sources, and the causes of their variability and their effects on the SEP properties are needed to improve agreement between the simulations and observations.
