Decoration of disclinations by solidification-induced band texture and focal-conic texture for a low-molar-mass liquid crystal

Two decoration techniques, solidification-induced band texture decora tion and focal-conictexture decoration, have been established to exhibit the director field of disclinations in a low-molar-mass methacrylate liquid crystal. The disclinations with strength s = 1/2 and s = ±1 are observed by the two decor ation methods. For the solidification-induced band texture decoration, the molecular orientation is perpendicular to the direction of the band. While for focal- conictexture decoration, it has been proved by the results of IR dichroism that the direction of the director is parallel to the direction of the focal-conic. Therefore, the sketch map of the molecular director filed can be mapped according to the morphological pattern of the solidification-induced band textureor focal-conic texture.     

通道不一致性、互耦对最优阵列处理器的影响

本文研究了通道幅相不一致性、互耦这两种误差对最优阵列处理器性能的影响。理论分析结果表明,对于只利用干扰加噪声协方差矩阵求逆的自适应方法(简称NAMI法),当干噪比(JNR)较大时,这两种误差不会导致零点位置的漂移,但零点深度有所变化;对于信号加干扰和噪声协方差矩阵求逆自适应方法(简称SPNMI法),当信噪此(SNR)较小或较大时,零点位置变化不大,但性能损失比NAMI法严重得多。如果能加以补偿,则SPNMI法与NAMI法有相同的结果。我们用矩量法计算得到的互耦矩阵对此进行了仿真模拟,实验结果证明了理论分析的正确性。

有色金属冶炼厂回转干燥窑分布式控制系统

对于锌湿法冶炼过程中的回转干燥窑控制问题,本文提出一种温度场控制方案,它由负压控制、温度和煤气流量串级控制以及含氧量控制来实现。基于这个控制方案,一个回转干燥窑分布式控制系统已经建立在某有色金属冶炼厂。本文介绍控制系统设计中使用的理论和技术。     

用于CIMSERC网络性能评价的NPES设计与实现

分析建模的方法用于CIMS网络性能评价是有其局限性的。本文介绍的是一个基于仿真方法的CIMSERC网络性能评估模拟器——NPES的设计与实现。该NPES可作为进行CIMSERC网络性能评价的“实验床”和评估工具.CIMSERC网络的基本结构是二个互连的基于Ethernet的TCP/IP网,设计中用于观测和评价的性能指标包括:网络系统的吞吐量、利用率、以及信息包传输延迟等。CIMSERC的NPES用SIMAN和FORTRAN语言混合实现。
