特异意识状态：新的领域

日渐明显的是,许多特异意识状态(ASC)和相关问题可以进入科学探索的领域.许多这些主观的状态或现象原先被归类为本质上是宗教的或神秘主义的,因而作为非客观的、非物理性的或不属于普遍的观察而被排除于科学研究之外.这种态度正在改变.首先是因为主观——客观二分法的困境证明了意识的重要性;其次是因为技术的发展使得发现主观状态的生理相关性成为可能——例如,现在可以通过快速眼动和脑电图记录探查和监督做梦.作为这些进展的结果,先前的这些神秘主义主题正转向科学证实和探索的领域.

惯性导航系统的控制理论方法

本文从控制理论的观点探讨了分析了惯性导航系统（ＩＮＳ），提出并了线性误差模型，计算了几种特殊情况下的特征值，表明推导特征值的准确表达式和通常采用的表达式稍有不同，分析了ＩＮＳ在静态初对准和标定过程中的可观测性，引入了基于物理本质的变换，能较容易地用检验新的动态矩阵来确定不可观测子空间及状态变量，最后提出了系统可观测性与估计量的特性之间的关系。     

新春寄语

1974年,为了加强学术交流、提高科研水平,北京强度环境研究所(702所)开始公开发行《强度与环境》刊物。《强度与环境》立足北京强度环境研究所的专业技术,面向整个专业领域,讨论有关结构强度、可靠性工程、环境工程等方面的技术问题。32年过去了,北京强度环境研究所依托航天高技术优势,逐步完善了试验分析手段,积累了丰富的试验研究经验;《强度与环境》则发表了大量的研究论文,组织出版了多项影响深远的技术文集,在成为各个高校和科研单位之间技术交流的窗口同时,也成为技术人员相互交流的平台。《强度与环境》刊物严谨的工作作风在高校和科…     

New results for the space radiation environment of MIR space station obtained by Liulin dosimeter-radiometer. Comparison with LET spectrometer NAUSICAA

Since 1988 high sensitivity semiconductor dosimeter-radiometer “Liulin” worked on board of MIR space station. Device measured the absorbed dose rate and the flux of penetrating particles. The analysis of the data hows the following new results:

In October 1989 and after March 24, 1991, two additional stable maximums in flux channel were observed in the southern-eastern part of South Atlantic Anomaly (SAA). These two maximums existed at least several months and seem to be due to trapped high energy electron and proton fluxes. In April 1991 additional maximums were localized in the following geographical coordinates regions: LATITUDE = (−35 °)–(−50 °) LONGITUDE = 332 ° − 16 ° and lat.(−46 °)–(−52 °) long. 360 ° − 60 °. Additional maximums diffusion occurs inside radiation belt. Appearance of these maximums seems to be closely connected with preceding powerful solar proton events and associated geomagnetic dynamics of new belt disturbances. After the series of solar proton events in June 1991 we observed significant enhancement of this new radiation belt formation. To achieve sufficient accuracy of dose rate predictions in low Earth orbits the structure and dynamics of new belt should be carefully analyzed to be included in a new environment model.

From the inter comparison of the data from “Liulin” and French developed tissue equivalent LET spectrometer NAUSICAA in the time period August–November 1992 we come to the following conclusions: Mainly there is good agreement between both data sets for absorbed dose in the region of SAA; Different situation of the instruments on the station can explain the cases when differences up to 2 times are observed; At high latitudes usually the tissue equivalent absorbed dose observations are 2 times larger than “Liulin” doses.
