Optimal H∞ general distance problem with degree constraint

In this paper the optimal H_∞, general distance problem, for continuous-time systems, with a prescribed degree on the solution is studied. The approach is based on designing the Hankel singular values using an imbedding idea. The problem is first imbedded into another problem with desirable characteristics on the Hankel singular values, then the solution to the original problem is retracted via a compression. The result is applicable to both the one-block and the four-block problems. A special case is given for illustration.

本文提出了属性相关表这样一种新的概念，定义了相应的运算并研究了它的有关性质及定理，在此基础上提出了用属性相关表求关系模式全部主属性的等级，并给出了用主属性来组合关系模式全部候选关键字的算法，上述算法的时间复杂度均为Ｏ（ｎ＾２）。     

我国氟碳铈矿选矿生产工艺进展

自１９９４年以来，随着轻稀土产品市场的好转，稀土行业的龙头工艺—稀土选矿生产工艺流程也得到了促进与发展，涌现出几种新的生产工艺流程和稀土矿物浮选药剂。本文就我国内蒙古白云鄂博矿、四川冕宁矿、山东微山矿的稀土选矿工艺流程予以介绍，并对上述地区生产工艺中存在的问题加以讨论。     

Gamma ray irradiation induced point defects in BaF2

There are some original nonmagnetic point defects in the BaF2 crystallite powder,such as interstitial and vacant F^- which can become paramagnetic centers by γ-ray-irradiation at room temperature,Afterγ-ray irradiation the paramagnetic point defects Vk,H,F and M centers,have been observed in the sample with experiment of electron spin resonance(ESR).Frenkel exciton,a nonmagnetic point defect,can also be induced by the γ-ray irradiation in the sample at room temperature,the existence of the Frenkel exciton is affirmed by an anomalous change of the ESR signal of Vk center with temperature,The signals of the ESR of the H,F and M centers weaken and vanish with the temperature increasing monotonously,But the ESR signal of the Vk enhances when the temperature goes up about 127℃,then weakens and vanishes.An increase in the Vk center follows an annihilation of the Frenkel exciton with heating.     

A 3-D motion tracing system in High School Physics teaching

Abstract This article presents a study of a large scale incorporation of one data acquisitionsystem into physics teaching in Israel. By 1994 about 30% of the schools throughout the country used the V-scope, a 3-D multibody motion tracing system, in their lab programme. The views and reactions of post-training teachers, experienced teachers and students on various aspects of using the system are described, analysed and compared.     

冲裁模CAD／CAM结构库之原型法

本文首先给出了一种新的2.5D 实体表示法,然后在此基础上提出了“原型”的概念。原型法的思想运用在结构库的管理中主要体现在它将模具结构与构成这种结构的零件之间的强联系变成弱联系,结构库面向的对象是一个具有整体性和可运算性的结构原型。这样的原型结构库基本上达到了通用性与开放性的要求。
