极值法膜厚控制的误差分析及其改进设计

分析了光学薄膜厚度的极值控制法,并利用矩阵的方法给出了极值法膜厚控制误差。基于极值法膜厚控制的原理,利用由IC/5薄膜沉积控制器和晶震探头组成的反馈系统,控制蒸发速率的大小,光控的信号由可编程的计算机探测接收。分别对ZrO2/SiO2,膜料进行了两组交替镀制实验测试。结果表明,整个系统稳定性好,自动化程度高,膜厚控制精度在1 02%左右。

TWO POSITIVE SOLUTIONS FOR A CLASS OF SINGULAR BOUNDARY VALUE PROBLEMS

An existence theorem of two positive solutions of the singular BVP1/(p(t))(p(t)y′(t))′+λα(t)f(y(t))=0,t∈(0,1),αy(0)-βp(t)y′(t)=0=γy(1)+δp(t)y′(t)was established by using topological degree theory.     

Besov regularity for second order elliptic boundary value problems with variable coefficients

This paper is concerned with some theoretical foundations for adaptive numerical methods for elliptic boundary value problems. The approximation order that can be achieved by such an adaptive method is determined by certain Besov regularity of the weak solution. We study Besov regularity for second order elliptic problems in bounded domains in ℝ ^d . The investigations are based on intermediate Schauder estimates and on some potential theoretic framework. Moreover, we use characterizations of Besov spaces by wavelet expansions. This work has been supported by the Deutsche Forschungsgemeinschaft (Da 360/1-1)     

THE VALUE OF COMPOSITION GAMES AND （0,1） NORMALIZATION GAMES （ Ⅰ-Ⅱ ）

In this paper we have studied n-person game problems of (0,1) normalization and composition. Also we have concerned multilinear extensions of composition games and especial games [5-7,9-14]. As we have studied Shapley value [1-4,15], we will give some proofs of the the orems.
