Research on CAD/CAE Information Integrated System Based on Web Services Tao Chen1, a 1College of Mechanical and Electronic Engineering, Jingdezhen Ceramic Institute, Jingdezhen 333403, PR China aemail: rosechen223@yahoo.com.cn Keywords: Web Services, CAD/CAE, Information Integration, PDM Abstract.
CAD/CAE technology undertakes the key work of product or project design in programming, computational analysis, optimization design, engineering drawings, technical documentation, assembly simulation and testing, preparing process, production management and other aspects.
In this information integrated system, CAD/CAE informatin integrated content mainly includes the following three aspects: (1) Information integrated between 3-dimensional components model of product and 2-dimensional engineering drawings. (2) Information integrated between CAD 3-dimensionsl model data with analysis and processing model.
During finite element analysis, we can extract geometry, material and other information directly by the use of three-dimensional solid model which generated by CAD design. (3) Query and unified management of various internal design data, results of design or calculation.
VRML graphics can not only transmit 3-dimensional information of model to Internet users, but also prevent the disclosure of engineering data.

Introduction In recent decades, titanium dioxide (TiO2) has been widely investigated as a key material for various strategic applications in the field of photocatalyst and photovoltaics, gas sensors, medical implants, and optical coating [1].
In solar energy conversion, for example, one-dimensional (0-D) materials have shown several advantages because of their unidirectional electron transport properties [3].
For reference purposes, XRD patterns of TiO2 P25 Degussa used as the starting material for the formation of nanotubes is given in Fig. 1.
