Bang bang control of unified chaotic system

The unified chaotic system contains the Lorenz system and the Chen system as two dual systems at the two extremes of its parameter spectrum. This paper presents the design of bang bang controller for unified system and multitude of numerical experiments under various control parameters. Numerical experiments meet the theoretic proof perfectly and convincingly demonstrated the controller can be effectively used for unified systems with uncertainty of the equilibrium points. The method enriches the applications of chaotic control.

电磁相分离法制备自生表层复合材料

采用电磁相分离法制备出以初生富铁相（AlSiFeMn复杂金属间化合物）为增强相，表层硬度为HB62．25，基体硬度为HB59．00的Al-11.70%Si-1.20?-1.50%Mn合金自生表层复合材料，增强相的显微硬度为HV 842。87，大小为20－80μm，该表层复合材料同基体材料相比，耐磨性提高了57．41％，所用方法工艺过程简单，成本低，为解决材料在服役环境中不同部位，不同性能的问题提供了新途径。     

Refractive-diffractive visual system for micro-display of LCOS

One head-mounted display visual system for computer entertainment and three-dimensional display of virtual-reality was achieved, which consists of a hybrid refractive-diffractive eyepiece and a relay reflector. It can be used in micro-display of liquid crystal on silicon (LCOS) diagonal of 18 mm. The whole system has better performance, with 60° field of view, 10 mm exit pupil, 23 mm eye relief, and reduces weight and size.     

管理系统的最经济控制问题

依据最经济控制问题的概念及其对无确定性数学模型系统分析存在的局限性，对现代管理系统最经济控制问题，提出了在满足系统基本要求前提下。实现控制功能及品质与控制成本比最佳或最划算的模型定义，并对管理系统的可靠性、ABC管理法、WSR方法论等方面的可靠性成本、运行成本和最佳收益等最经济控制问题进行了研究．     

大豆开花期缺水和遮光处理叶片解剖结构的观察

大豆珍珠塔3号具有双子叶植物叶片结构特征,但在海绵组织最上层有一层特殊细胞——平脉叶肉细胞,此层细胞具有水平运输和气体交换的特殊作用。大豆开花期光照对叶片结构发育起主导作用;水分亦是影响叶片结构发育的重要因素;光弱块水条件下,大豆表现出对光的竞争比对水的竞争更明显。     

GRAMMATICAL COMPLEXITY OF FEIGENBAUM TYPE ATTRACTORS IN PERIODIC WINDOWS

In [7,8] the grammatical complexity of the Feigenbaurn attractor and the general Feigenbaurn attractors, generated by period - n - tupling, are studied. In this paper we study the grammatical complexity of the Feigenbaurn type attractors, including Feigenbaurn attractors and general Feigenbaurn attractors,in periodic windows. It is shown that the languages determined by these attractors are CLS and are. not CFL.
