Rats in a transparent morris water maze use elemental and configural geometry of landmarks as well as distance to the pool wall

The aim of this study is to evaluate whatare the dimensions of a panorama of discretelandmarks that a rodent will store in order toreturn to a previously visited target. Ratswere trained to locate a hidden platform in acircular pool of clouded water set within aquasi-spherical enclosure. In order to find theplatform, they had to learn the geometricrelations between the platform and asurrounding set of three discrete landmarks,highly visible through the transparent wall ofthe pool. In test trials without a platform,the array of landmarks was so manipulated as todissociate the effect of actual distance to thelandmarks, of their angular separation, and oftheir apparent dimension. Animals were shown torely equally on angular separation and apparentdimension. The role of actual distance couldnot be definitely ascertained, as animals wereshown to additionally rely on the distance tothe pool wall in order to locate theplatform.     

机动再入飞行器自适应飞行控制系统设计

研究机动再入飞行器的制导控制问题。为了解决机动再入飞行器气动系数变化范围大、气动耦合严重和气动参数非线性过零常值大等恶劣条件下的控制，并且能充分利用飞行器可测量信息提高系统自适应能力，本文提出了状态方程参数辨识－－极点配置－－前馈补偿自适应控制的飞行控制系统的设计方法。通过对新型号再入飞行器的制导系统仿真，可以看出该控制系统使其有很好的飞行性能。

Space traffic control: a view of the future

This paper provides an overview of a system for providing reliable, ongoing, timely situational awareness services to satellite operators. Such services would include close approach warnings, warnings of potential radio frequency interference, and other offerings designed to help make operators aware of possible threats to the safe operation of their spacecraft and measures they can take to lessen these threats. The paper discusses current trends, proposes operational requirements, and speculates on the type of organization that may emerge to provide space traffic control services. It highlights how the detailed information required for such services may affect the evolution of the use of space.     

尺寸参数对气动液阀启动特性的影响

为气动液阀的启动过程建立了数学模型，分析了尺寸参数对该阀启动特性的影响。计算结果表明：在保证必要的工作寿命的前提下，适当地增大控制腔气孔的直径或增大靠近控制腔的活塞端面直径有利于提高该阀的响应能力。本文所得的结论有利于此类阀门的设计。
