This paper outlines the application of wavelet analysis method to computering wear par-ticles image processing and introduces the concept of grain parameter for wear particle imagebased on statistical feature parameters. The feature of wear particles image can be obtained fromthe wavelet decomposition and the statistics analysis. Test results showed that grain parametercan be used as a synthesizing feature parameter for wear particle image.

An algorithm for solving the graph isomorphism problem with 3-D DNA structures is proposed in this paper. The k-armed branched junction molecules are used to code k-degree vertices. Double stranded molecules are used to code edges. Then the molecules are mixed in a tube to be ligated. The result can be detected by gel electrophoresis. The time complexity of the algorithm is O(n2), where n is the number of vertices of the graph.

＜正＞Aimed at the complicated system engineering of plane layout scheme design of container Terminal, and based on the eM-plant distribute software have set up container terminal operating emulation modules, such as Berth module, Gate entrance module, Storage module and Statistic module. Have set up the comprehensive evaluation system of plane layout, and the right of every index was confirmed by Analytic Hierarchy Process method and Expert Consult method synthetically. By Analyses the level of every index value that got from the emulation results, can get the comprehensive valuation result. Have carried on intelligence optimized research by using VR-UC GA algorithm on the overall arrangement scheme, and applied to a certain container terminal program project, have gotten relatively satisfactory result, offered strong support for decision of container terminal’s plane layout scheme.

In this paper, the transportation mode of tube during the immersed tunnel engineering in Yangtze River incorporated, mathematical models of the combination of the tube and four barges are established when it is towed by a tugboat through an elastic rope and pushed by two pushers. Based on evaluating the hydrodynamic derivatives by regressive formula, the simulations and analysis of the whole maneuvering motion course are accomplished. They include sway and yaw motion simulation of the combination and prediction of maneuvering motion such as turning circles of different rudder angle under the condition of being pushed by two pushers. The coincidence of the prediction with the results of model test is good.
