Tetracentron sinense and Trochodendron aralioides are two Tertiary relict species of large trees in the family Trochodendraceae with narrow distributions on the mainland and islands of eastern Asia. They belong to the order Trochodendrales, which is one of the four early‐diverged eudicot lineages. These two relict species provide a good system in which to examine genomic changes that occurred as they...
We show the manufacturing procedure of the test specimen of the compound bioceramic artificial bone, conduct experiments to measure its fracture toughness, and conclude that the experiment data conform to the two‐parameter Weibull distribution with scale parameter β = 0.527369 and form parameter α = 5.24317. Furthermore, compound bioceramic artificial bone is of a high level of crack sensitivity and...
Reliability distribution for impact toughness after strain aging of 38 mm thick ADB610 steel was investigated. The reliability distribution model was established by using least square method and correlation coefficent maximization method. Then the hypothesis test was calculated by using correlation coefficent test and K-S test method. It can be concluded that the impact toughness after strain aging...
In this paper, the classical fractal graph - Koch curve was generated with unitary regulation of L system in visual C++, and the regular fractal graphs, fractal trees and handkerchief curves which have typical fractal characteristics were generated by changing the elements of generation. The unitary regulation of L system is intuitively expressed by computer language, it can not only help to understand...
Reliability distribution research on welding defect size is carried out based on physics failure background and mathematical statistics. The research shows that the defect ratio is invariable in a certain weld metal area, which is deduced that welding defect size obeys exponential distribution. By means of least square and correlation coefficient maximum method, it is found that the exponential distribution...
Based on the fractal theory, recognize the new design language - fractal unit design, understand the normal source elements and morphological evolution laws of fractal unit design, Interpret the impact of fractal unit design theory on product modeling design. According to the fractal self-similarity, induce five typical morphological evolution laws, and take examples about their uses in product modeling...
In the light of the internal configuration pattern of Dongba Characters, this paper proposed the concept of “graph element”. Based on the concept of “graph element”, the author explained associative element-combining configuration of Dongba Characters, and analyzed the use of graph and meaning and the 3 major features, which are position, color and size ratio, in both homo-graph element and hetero-graph...
The product innovation contains a series of knowledge activities, such as knowledge assimilation, conversion, creation and dissemination. Knowledge management is the crucial issue for the efficiency and quality of product innovation. In this paper, a knowledge fermenting (KF) model has been applied to analyze the process of product innovation. The key factors and feedback control of knowledge fermenting...
In this paper interface problem for industrial design is researched. Effective interface management plays an important role in success and efficiency for industrial design and innovation activity of enterprise. Industrial design is a borderline subject intersected by trans-disciplinary and grows up with the development of great industry. Industrial design just like a bond in industry society to connect...
This paper researched the development and application regarding the black pottery's rapid prototype. The Tibetan nationality's Nixi black pottery is the nationality's traditional handcraft that possesses a long history and contains both actual functions and also beautifully appreciated value, while from the Nixi black pottery to the colorfully engraved black pottery, and from the primitive wheel-less...
By exploring the microstructure of the dynamic languages of animation characters, this article studies the application of the "microstructure" thinking of the dynamic languages of animation characters in design. The articulated structure of linguistic symbols of the movement of animation characters has been analyzed and the concept of symbolic space in the design of the dynamic languages...
This article focuses on the symbols of the motion of animation characters from the perspective of semiotics, and a new approach for the design of the dynamic language of animation characters has been searched. The conclusion we draw in the article is that the dynamic languages of animation characters are symbols in nature. Basically, the dual features of the dynamic language of animation characters...
Knowledge becomes the most important strategic resource of product creative design. Knowledge fermentation based on RP is that new creativity (knowledge) becomes a physical prototype which full of new knowledge under the control of RP(knowledge enzyme) in the environment of constitute of rapid prototype technology platform and creative design system. Knowledge fermentation model is established according...
