摘要：The basic biomechanical laws that apply to the clawed toes of animals with powerful digging abilities and the optimal bionic design of curved soil cultivating components with an analogous contour were researched in a novel way. First, the curvature and profile of the inside contour line of a field mouse’s clawed toe were analyzed. The finite element method (FEM) was then used to simulate the working process in order to study the changing characteristics of the working resistance of bionic soil- engag- ing surfaces and the stress field of the processed soil. A straight-line cultivating component was used for comparative analysis. In accordance with the simulation results, a series of soil cultivating com- ponents of varying design were manufactured. An indoor soil bin experiment was carried out to meas- ure their working resistance and validate the results of the FEM analysis. The results of this research would have important values in the optimization design of cultivating components for energy and cost savings.

摘要：This paper uses the component-based technology and the object oriented simulation technology to analyze the UUV navigation and control integration simulation system. We divide the system into components based on its structure, and describe every component using active diagram. By using the component-based technology, the system described here is easier to extended and be reused. At last, it realizes the whole UUV integrated navigation simulation course using the system to validate the availability.

摘要：In the study, E. sibiricus L. cv. chuancao No. 2 was allocated to plots in a randomized block design with five row gradients （30, 45, 60, 75 and 90 cm）. At the flowering stage, the root, stem, leaf and inflorescence of population, as well as the quantitative traits of components, biomass structure, accumulation and distribution proportion of energy were measured and analyzed. For different row spacings, there are highly significant differences between total tillers and ratio of fertile tillers per square meter and significant differences among the eustipes length, eustipes number and natural height of each tiller; but there are no significant differences among the leaf length, leaf width and leaf number of each tiller. A significant difference is found between the depth and distribution range of root, inflorescence stalk, and ear number of fertile tillers, and the biomass of leaf, stem, root and inflorescence. The influenced order is stem 〉 leave 〉 root 〉 inflorescence. No significant influence is found among the energy values of single leaf, stem, root and inflorescence; but a significant influence is found among the energy accumulation of the leaf, stem, root and inflorescence with the effect degree being stem 〉 leaf 〉 inflorescence 〉 root. Significant differences are also found among the energy distribution of each component with the order of leaf〉 stem 〉 inflorescence 〉 root.

摘要：A knowledge-based system in structural component design based on fracture mechanics is developed in this paper. The system consists of several functional parts: a general inference engine, a set of knowledge bases and data-bases, an interpretation engine, a bases administration system and the interface. It can simulate a human expert to make analysis and design scheme mainly for four kinds of typical structural components widely used in shipbuilding industry: pressure vessels, huge rotation constructions, pump-rod and welded structures. It is an open system which may be broadened and perfected to cover a wider range of engineering application through the modification and enlargement of knowledge bases and data-bases. It has a natural and friendly interface that may be easily operated. An on-line help service is also provided.

摘要：According to the morphological structure characteristics of plants, the de- velopment mode for component-based virtual plants software was put forward, and the internal structure of plant organs component under this mode were analyzed, thereby, the overall design mode for virtual plants software was given out, and its characteristics were estimated. Compared with traditional development modes of virtual plants software, component-based virtual plants software had significant advantages in code reusing, development efficiency and expansion of software functions.

摘要：Business applications are subject to changes with technology trends or market demands. However, quick response to these changes is still a challenging issue. Most of the existing architectures （e.g., CORBA, Web Services） still expose the developers to excessive low-level details and force a tight coupling between program modules. For end users, developing, customizing, and reengineering applications remain difficult and time-consuming tasks. A high-level programming model is presented, together with a descriptive programming paradigm called BEAP, to facilitate end-user programming. In this approach, applications could be visually composed from well-defined software components called ＂funnels＂ in an event-driven fashion. Application examples have shown that, by raising the level of abstraction as well as simplifying the programming model, BEAP could empower end users to build business applications on demand with improved productivity.
