偶联剂对玻璃纤维/环氧基复合材料界面介电性能的影响研究

本文研究了五种偶联剂对玻璃纤维浸润性能和玻璃纤维/环氧基复合材料界面介电性能的影响。结果表明,玻璃纤维经偶联剂处理后,其浸润活化能降低,与环氧树脂基体间的相容性及化学反应活性得到改善;因此赋予了玻璃纤维与环氧基体间以良好的界面粘结性能,从而提高了玻璃纤维/环氧基复合材料界面的介电性能。其提高的幅度大小与偶联剂的极性及化学结构有关。     

Multicast key distribution schemes based on Stinson-Van Trung designs

The efficiency characteristics of multicast key distribution schemes based on (v, b, r, λ)-designs are investigated. The stability and connectivity of such designs are estimated. These estimates generalize and enhance the well-known estimates for the efficiency characteristics of multicast key distribution schemes based on incomplete block designs. __________ Translated from Kibernetika i Sistemnyi Analiz, No. 3, pp. 100–111, May–June 2007.

Developing real-time knowledge-based systems with PERFECT

PERFECT (Programming EnviRonment For Expert systems Constrained in reasoning Time) is aimed at providing the necessary engineering support in real-time knowledge-based system development. PERFECT bridges the gap between the traditional analysis and design methodologies, and the implementation tools for these systems. It does so by providing the means to construct a knowledge model and to choose a suitable inference strategy. Subsequently the properties of the knowledge model and inference strategy may be analysed. For instance, it may be checked whether the knowledge model contains sufficient knowledge to diagnose a fault in an industrial process. Moreover, it may be checked whether the inference engine is able to provide an answer to a certain problem in time. If not, the analyser of PERFECT proposes an alternative structure of the knowledge model. When the constructed knowledge model and the chosen inference strategy show the required time efficiency, the compiler of PERFECT may translate them to an actual real-time knowledge based system in COGSYS. In addition, guidelines are provided with respect to the design of the human-machine interface. The resulting system is an instrument—a source of information that can be used by the human operator during problem-solving, rather than a prosthesis—a device that solves the entire problem by itself and presents the outcome to the human operator.
