Abstract: In the digital animated films of the U.S.A, the frontier technology is CG (Computer Graphics). This paper, based on the study of American CG animated films, analyzes the unique architectural designs in these films and further points out that CG has brought unprecedented impacts on the traditional animated films. Thus, the architectural designs have been changing in the animated films of the U.S.A..

Abstract: [Aim] The thesis is mainly about the great impact of cross-cultural communication and cooperative learning in web environment on students’ foreign language level, cultural awareness, affective factors, cooperation ability and independent ability. [Methods] We carry out practical activities of cross-cultural communication and cooperative learning by means of experimental teaching, video conference, E-mail inside and outside the class and giving priority to computer aided international cultural exchange form, as en elective course. [Result] Most students are positive about cross-cultural communication and cooperative learning under web environment in developing students’ cooperation ability, independent ability, affective factors and cultural awareness(M=4.059, SD=0.732). Subjects who are convinced to totally convinced that web learning environment greatly enhanced their cooperation ability and independent ability account for 92.4% and 78.2%; subjects who greatly approve that the web environment does good to learning account for 72.4%; students who agree the web environment could improve developing positive emotion in learning account for 88.8%; and also 84.1% of subjects believe that the web environment can improve their cultural awareness in language learning. [Conclusion] Cross-cultural communication and cooperative learning in web environment offer an ideal learning environment, increase opportunities to output or input, improve their cultural awareness in language learning, encourage and support affective factors beneficial to language learning and develop consciousness and ability of self-studying and cooperation.

Abstract: In this paper, we use the analysis of the time, knowledge and logic attributes of the risk, furthermore, to define, recognize and classify it based on the identification of the risk of large design enterprise project. We also put forward the thought and basic methods of building hall structural system of complex project risks, using it to establish hall structure system of large design enterprise project risks and point out the support that the system will provide for the risk assessment and strategy choice.

Abstract: In this paper, the theory of apparent permeability and effective permeability of the core is described. The apparent permeability with coil in different positions of the core is investigated and simulated by HFSS. The best location of the coil is determined according to the curves of the apparent permeability. The relationship between the effective permeability and aspect ratio of the core is investigated and compared with the theoretical derivation, verifying the accuracy of theoretical analysis. Specification of core in shape is solved. Core losses are further discussed. Quantitative analysis of core losses is obtained.

Abstract: The mechanism of the orthogonal fluxgate is much more complex than that of the parallel fluxgate. Quantitative analysis on the orthogonal fluxgate has been seldom reported. In this paper, we analyzed the orthogonal fluxgate quantitatively. For an anisotropic soft magnetic material, the 3-D hybrid Jiles–Atherton/Stoner–Wohlfarth magnetic hysteresis model only provides semi-quantitative analysis. When the material of the senor is isotropic, a little modification was made on the 3-D hybrid Jiles–Atherton/Stoner–Wohlfarth magnetic hysteresis model, and the simulation after modification is more reasonable.

Abstract: Pretreatment of silicon wafer surface is the key factor to successful Low Temperature Si/Si Direct Bonding(LTSDB). Different cleaning methods are taken as pretreatments and corresponding levels of hydrophilicity are achieved. The obtained result shows that the RCA1 cleaning can improve the hydrophilicity on a large scale, plasma can also increase it but the treating time must be controlled carefully. The experiment provide confidential message for the realization of LTSDB.

Abstract: Aiming at time and sensor system errors which are influential on detecting precision of sensors, the transfer relation of time and sensor system errors is modeled and a least square estimation algorithm is presented, based on navigation data with high precision and real-time observation of an aerial platform. Contrast among true value, observation and registered value by simulations show that the registration algorithm of time and sensor system errors for multi-platform can converge quickly with high precision.

Abstract: In order to further improve the overall efficiency of retrieval system, it proposes a method of inverted index based on block organizing technology. The specific studying process is as follows. Firstly, retrieval performance model of inverted index is generated based on data statistics, and then analyze the organizational strategy of inverted file block index, finally, retrieval performance model is verified through simulation experiment. The result shows that the method of inverted file block organization can get higher algorithm efficiency under the condition of less cycle numbers in the search algorithm, and also reduce the execution time of search algorithm significantly, which can verify the feasibility of inverted file block index method.

Abstract: Understanding marine biogeochemistry requires a network of global ocean in situ monitoring of various parameters on different scales in time and space. Among the various parameters involved in marine biogeochemistry, sediment chemistry is most important, and the organic matter fractions are the dominate factor in this parameter. However, classical methods of determining organic matter fractions consume a great deal of time and labor. In addition, some of these methods can produce high levels of pollution and are therefore not suitable for in situ studies. This study explored a method of rapid determination of organic matter fractions by ozonation chemiluminescence. In this method, the organic matter was separated into extractives, acid soluble fractions and acid insoluble fractions (AIF) using the classical method and then oxidized by ozone. The ozonation chemiluminescence characteristics of eight samples were subsequently used to set up a model to predict the concentrations of organic matter fractions. The model was tested using nine other organic samples and the results showed that it provided a better fit for the predicted acid soluble fractions. This study is the first to demonstrate the use of ozonation chemiluminescence for rapid determination of organic matter fractions; however, further study is required to enable its universal use.

Abstract: The author proposes a scheme of flash automatic marking based on animation effects. Describe the question's marking information by using the logical formal method. Achieve automatic marking by building the logical formal system. Focuses on two components of the scheme: logical formal description and SWF to XML. Describes the whole process of logical formal marking with example. Analysis of manual and automatic marking shows that: logical Formal automatic marking error is better than the manual average error.
