A C++ program is developed for composing the stiffness matrix of the temperature field, saving it in changing bandwidth method and calculating the linear algebraic function group through using the Gauss eliminating method. A module for drawing the color fringe of tire temperature field is created, which makes the result more visual. Taking the 9.00-20 cross-ply tire on CA1092 as an example, the finite element numerical simulation analysis of automobile tire 2-D steady temperature field is completed. Through comparing the result with the analysis data by ANSYS, this software is proved to be capable of the modeling, calculating and post-processing of FEA of automobile tire 2-D steady temperature field.

A novel carbonyl transposition led by anilines'nucleophilic addition to methyl 2-keto α-D-glucopyranoside was discovered. And the mechanism of the reaction concerned to an enol rearrangment was provided through tracing the change of 〓H-NMR and 〓C-NMR of a hemiacetal intermediate which was obtained in the reaction of o-phenylene diamine with 2-keto glycoside. Both the intermediate and the converting product were identified by 〓H-NMR,〓C-NMR,〓H-〓H COSY and HMQC.
