Steels containing different carbon contents (0.085% C and 0.380% C) had been chosen for this purpose. The main advantages of factorial design are its easy implementation and the effective computation compared with the other optimization techniques, which were employed for predicting mentioned responses in the literature. To verify the proposed approach based on factorial design, experiments for verification were performed. The results of the verification experiments and the mathematical models are in accordance with each other and the literature.展开更多

Compared with the interior design activities, the furniture is one of the important factors in the process of the interior decoration. The choice of the appropriate furniture not only can effectively improve the quality of the interior design activities, but also can fully meet the specific application needs of the people. This paper starts from the analysis of the specific requirements on the design and production of the modern furniture. And combined with the analysis of the specific characteristics and the connotation of the design styles of the furniture in the Ming Dynasty, the author further explores the specific influence of the design styles of the Ming Dynasty furniture on the modern furniture.展开更多
