A new method for electronic circuit fault knowledge automatic generation Using PSpice has been put forward based on summarizing development of the intelligent fault diagnosis technology. A new algorithm of generating fault knowledge automatically has been designed by analysing the structure characteristics of the CIR file. The algorithm of search automatically has been designed by analysing the structure characteristic of the OUT file. The DC fault dictionary method has been improved and the fault order according to the minimum distance will guide the user to remove the fault. In the end, through these technologies, the fault knowledge query system has been empoldered. The feasibility of the proposed method has been proved by experiment results. © (2013) Trans Tech Publications, Switzerland.

Multi-scroll chaotic attractors synchronization technique is a research focuses in recent years. This paper focuses on multi-scroll chaotic attractors in the four-dimensional system. It uses variable feedback synchronous method to achieve the two 4-scroll chaotic attractors’ synchronization. The feasibility of this method is proved by theoretical analysis and numerical simulation. Simultaneously, it gets a better synchronization results. © (2014) Trans Tech Publications, Switzerland.

The Pspice which is a simulation circuit simulation software is powerful, but the graphics are still defects, and MATLAB can make up for the shortcomings. In this paper, on the basis of analyzing the characteristics of the Pspice software output file created in the MATLAB M file, the method based on multi-resolution analysis to extract the fault feature, can solve the problem of the data transmission between the two, and example verification. © (2014) Trans Tech Publications, Switzerland.

In this paper, J-integral of 3-zone inhomogeneous welded joint is calculated by use of the finite element method, and the impacts of yield strength matching factor and elastic modulus matching factor on J-integral are studied as well. The analysis results show that the yield strength matching factor affects J-integral value greatly, that is, low matching of inhomogeneous welded joint of same steel can help to improve the ductility of the welded joint and the influence of yield strength matching factor on J-integral is much greater than that of elastic modulus matching factor, so it plays a very important role in the engineering design. © (2012) Trans Tech Publications.

Bionic alumina samples were fabricated on convex dome type aluminum alloy substrate using hard anodizing technique. The convex domes on the bionic sample were fabricated by compression molding under a compressive stress of 92.5 MPa. The water contact angles of the as-anodized bionic samples were measured using a contact angle meter (JC2000A) with the 3 μL water drop at room temperature. The measurement of the wetting property showed that the water contact angle of the unmodified as-anodized bionic alumina samples increases from 90° to 137° with the anodizing time. The increase in water contract angle with anodizing time arises from the gradual formation of hierarchical structure or composite structure. The structure is composed of the micro-scaled alumina columns and pores. The height of columns and the depth of pores depend on the anodizing time. The water contact angle increases significantly from 96° to 152° when the samples were modified with self-assembled monolayer of octadecanethiol (ODT), showing a change in the wettability from hydrophobicity to super-hydrophobicity. This improvement in the wetting property is attributed to the decrease in the surface energy caused by the chemical modification. © 2011 Jilin University.
