Abstract: With catalysis system, carbonylation of methanol liquid is a better method in manufacture of acetic acid. However previous control mode can not well meet technique demands. This paper made some modification on reaction process control based on manufacturing technique. Aimed at much influence upon temperature including uncertainty, cross coupling effects and big delay about model, predictive functional control (PFC) technique combined with PID and feedforward are applied to temperature control of reaction process through supervisory total distributed control which leads to the improvement of regulatory capacity for both reference input tracking and load disturbance rejection. Practical results show stable and reliable system operation.

Abstract: How to master the technology innovation and method and technique in product exploitation, has been always one of the issues of research and discussion. Based on more than 40 years’ experiences of engagement in mechanical and electrical technology on product research, design, teaching, the author proposed and constructed "OF + N" theoretical method (for short: method of creating inventive and innovative topics) suitable for technological innovation and product development. Some innovative design was implemented using the theoretical method through years of research and probe.

Abstract: In this paper, polyethylene film was treated by APGDLD (atmospheric pressure glow discharge liquid deposition) to polymerize acrylic acid onto the surface to improve its hydrophilicity. The effect of APGD and APGDLD on the surface modification is compared. Influence of various treatment conditions on polymerization degree and contact angle such as applied voltage, discharge gap, reaction gas flow rate and treatment time were investigated. Treating effect was characterized via contact angle measurements, SEM and ATR-FTIR. The results indicated the hydrophilicity of the polyethylene film surface was enhanced and well reserved by APGDLD.

Abstract: How to score professional papers of university entrance art examination scientifically and correctly has been one of the concerns of the staff in scoring the art paper. This paper proposed and constructed the model of fuzzy comprehensive evaluation on art professional papers based on fuzzy theory aimed at many ambiguous factors in art papers under general requirements for visual effects in scoring process. The scoring experimental research was implemented on art professional papers using the scoring model and satisfactory results obtained. Therefore the theoretical and experimental basis was laid for practical application of the method.

Abstract: In this paper, MR damping mechanism is used to solve the vibration damping difficulties caused by the nonlinear vibration of ball mill. Dynamic model of MR Damper is constructed to design the damper of ball mill through research. Fuzzy control principle is adopted for active control of the MR damper and satisfactory results are obtained through computer simulation.
